Olympus EVOLT E-510 Review

by Bob Atkins

photography by Bob Atkins and Hannah Thiem

The Olympus EVOLT E-510 is a digital single-lens reflex (DSLR) camera designed for photographers who are upgrading from a P&S digicam or an earlier consumer DSLR camera. It was introduced in March 2007 and is the successor to the Olympus EVOLT E-500. The most significant changes are the addition of body-based image stabilization (via sensor shift), a Live View mode, and a higher pixel count sensor (10MP vs. 8MP).

The Olympus EVOLT E-510 can be purchased from amazon.com in the following combinations:

If you are new to digital photography, start with the photo.net article on "Building a Digital SLR System."

The Four Thirds system

All Olympus DSLRs are part of the "Four Thirds" camera system, which is characterized by their use of a 4/3" digital sensor which measures approximately 17.3mm wide by 13mm high. The Four Thirds name comes from the fact that the area of a Four Thirds sensor is approximately equal to that of the (long obsolete) 4/3" sized videocon tube, which was used in early video cameras. Four Thirds sensors are somewhat smaller than the more commonly used APS-C digital sensors, which typically measure around 22.2mm x 14.8mm in Canon cameras such as the Digital Rebel XTi and around 23.7mm x 15.6mm in Nikon cameras such as the D40x.

The rational behind using the smaller 4/3" sensor is sometimes debated. In theory it could make the cameras and lenses smaller, lighter and cheaper, though in practice that hasn't really been the case. Olympus takes the position that the lenses it makes for the 4/3" system are better optimized for digital use, and the smaller required image circle probably does help somewhat in that respect. On the other hand, for a given pixel count, the smaller the sensor the smaller the pixels must be and smaller pixels (all else being equal) lead to higher image noise. In the extreme case of P&S digicams this is quite obvious, but in the case of 4/3" sensor cameras the pixel size is similar enough to that of APS-C sensors that most users might not notice a difference.

In addition to the smaller size, Four Thirds sensors have a width to height ratio of 4:3, which is also the format ratio used by most P&S digicams. APS-C format sensors on the other hand have the same width to height ratio as 35mm film, 3:2. There's really no best width to height ratio since it depends on the size of the print you want to produce. While 4:3 images have to be cropped more than 3:2 images to make 4" x 6" or 8" x 12" prints, they need less cropping to make 5" x 7" or 8" x 10" prints.

All Four Thirds cameras have a lens multiplier factor of about 2x. The lens multiplier is the ratio of the focal length of a lens and gives a certain field of view to the focal length of the lens, which would give the same field of view on a full frame 35mm camera. Since Four Thirds and 35mm frames have a different aspect ratio the 2x factor is approximate. What it means is that you get about the same view with a 50mm lens on a Four Thirds camera that you do with a 100mm lens on a full frame 35mm camera.

The smaller size of Four Thirds sensors also results in an increased depth of field relative to larger sensors. On average you get about 25% more depth of field with Four Thirds than with APS-C for the same view. Again this is a mixed blessing/curse. If you want a landscape with extreme depth of field it's an advantage. If you want a portrait with the subject in sharp focus but the background blurred, it's a disadvantage. Since the difference is quite small though, DOF issues won't really be of great importance to most users.

Operating Speed

The E-510 is a responsive camera, if not relatively fast. Powering up takes around a second (in part due to the fact that it goes through a sensor cleaning cycle when the power is turned on), which is slower than many DSLRs. Recovery from sleep mode takes about the same amount of time.

Shutter lag after focusing is very short, with no discernible delay in normal operating mode. In LiveView mode there is a substantial shutter lag of about 1 second.

In continuous mode the E-510 can capture just over 3 frames per second and if photographing in JPEG mode with a fast CF memory card you can record around 20 images before the buffer fills and the frame rate drops. In RAW mode you can record about 8 frames before the buffer fills and the frame rate slows.

Controls

The E-510 uses a fairly conventional control layout. There's a rear LCD screen, which is used to display operating parameters and the various software menus. Menu navigation is done via a 4-way control switch (allowing navigation up, down, left and right through the menus). Shutter speed, aperture, and other parameters such as exposure compensation are set using a thumbwheel on the right side of the camera.

The 4-way controller, when not being used to navigate menus, doubles as a set of dedicated buttons for setting ISO, white balance, auto focus, and metering modes. There is a dedicated button to select between single frame, continuous, self timer, and wireless remote control operation and one that directly accesses the image stabilization setting (off, horizontal and vertical stabilization, vertical only stabilization). The Live View mode is also entered by pressing a single button.

I found navigating the menus to be a little confusing, but I guess it's something you eventually learn if you own the camera. One thing I did find inconvenient was switching between manual and auto focus. It takes 8 button clicks from the initial menu screen to navigate to the correct entry and select the mode. I have to say that a switch on the lens is a lot more convenient.

For a complete and detailed description of all the camera controls and options you can download a PDF copy of the user manual.

Auto Focus

The Olympus E-510 has only 3 AF zones, aligned horizontally across the frame. This is less then some of the competition (e.g., the Canon Digital Rebel XTi has 9), though in practice I didn't find it to be an issue since my normal mode of operation is to set AF to the center zone. If you're the sort of photographer who likes to let the camera make all the decisions for you, including where to focus, then you might find 3 zones to be a limitation.

Normal operation is focus priority, which means that if the camera hasn't locked focus, the shutter will not release. However, there is a menu option to change this to shutter priority, which means that the shutter will fire whenever the shutter release is fully depressed, whether the subject is in focus or not.

Manual focus can be enabled via a menu function, not a switch as is common on other cameras or lenses. There is no mechanical manual focus; the focus ring is used to drive the focus motor (referred to as "focus by wire"). Focus speed (the amount of focus change for a given rotation of the focusing ring) in manual mode is slow. This does allow very fine adjustment of focus, but it can make finding the focus point using the viewfinder screen difficult. Normally with manual focus you make slight movements of the focusing ring to take the image through the focus point and back to confirm visual focus. The slow focusing speed in manual mode makes this quite difficult if not impossible, though of course you can use the focus confirmation light in the viewfinder to establish the correct point of focus. While the menu allows you to select which way you want to rotate the focusing ring to go from near to far focus, there's no option to change the focusing speed.

There are 3 focusing modes: single shot, continuous (predictive), and manual. Single shot mode is normally used for static subjects while continuous mode is used for tracking moving subjects. However, you can also set single shot plus manual, where the camera will AF on a subject and then allow you to make small manual changes using the manual focusing ring. There's also a continuous plus MF mode in which you can manually adjust focus as long as the shutter is not depressed, but when you half depress the shutter continuous AF takes over.

Focusing was reasonably responsive under normal outdoor lighting conditions, but in dim light was a little slow at times. The AF assist light (strobing flash) often seemed to have to fire two or three times before focus was achieved, which wouldn't be good if you were photographing at a party and wanted to capture fleeting action.

Metering

The E-510 has three basic metering modes: multisegment, centerweighted, and spot. The multisegment metering, which Olympus calls Digital ESP Metering, uses 49 zones and applies an algorithm to determine the optimum exposure. The pattern can be linked to the AF zone selected if desired. Centerweighted metering places most emphasis on the center of the frame (the area most strongly weighted is shown by a circle in the viewfinder). The spot metering zone takes a reading from a small area in the center of the frame. The central focus zone markings shown in the viewfinder also serve to indicate the approximate area of the metering zone in the spot metering mode.

There are also two other spot metering modes, HI Spot and SH Spot. In HI Spot (highlight-based spot), metering is biased towards more exposure in order to render white subjects white rather mid-grey. Similarly SH Spot (shadow-based spot) biases metering towards less exposure in order to make dark objects (shadows) appear dark.

It's likely that most users will use the multisegment metering most of the time, and it generally does a pretty good job. However under sunny conditions, it's quite easy to blow out white highlights. This appears to be due to two factors. First the E-510 tends to overexpose a little in such situations and second, the default contrast setting may be a little high. Lowering the contrast setting helps a tiny bit in taming highlights and adding shadow detail, but the highlights can be brought under control more effectively by applying a small amount of exposure compensation, perhaps with -2/3 stop being a good starting point when you have white objects in bright sunlight.

LCD Monitor

The rear (and only) LCD screen is used to display camera information and menu settings as well as review images after photographing or provide a live display of the image when the Live View mode is selected.

The screen is a 2.5" HyperCrystal semi-transmissive TFT color LCD with 230,000 pixels. It is optimized for a wide viewing angle and the brightness can be adjusted via a menu setting.

Viewfinder

The Evolt E-510 has a viewfinder that provides 95% coverage at a magnification 0.92x with a 50mm lens. The viewfinder image is quite small, though perfectly usable in my opinion. You sometimes see complaints about small viewfinders, but after using a camera for a while I found that I really didn't notice that the viewfinder image was smaller than that which I'm used to in my EOS 40D. I'd estimate the E-510 viewfinder is about 75% of the size of the EOS 40D viewfinder

Displayed to the right of the viewfinder (rather than below it) are the essential parameters such as aperture, shutter speed, exposure mode, focus and flash confirmation symbols, exposure compensation setting and low battery warning. There are also indicators that tell you when you are not using auto white balance, when you have selected IS (Image Stabilization) mode, and when you are using spot or centerweighted metering.

There is no viewfinder readout of the ISO setting and there is no frame counter or remaining buffer size indication. Since the image stabilization is done by the camera body rather than the lens, you can't see the stabilization effect through the viewfinder and there is no indication of how steadily you are holding the camera as there is, for example, in the Sony A100, which also uses in-body stabilization.

The viewfinder screen is fixed and has markings for the 3 AF zones and a circle that shows the area emphasized by the centerweighted metering option. The center AF zone marking is also used as the spot metering area indicator.

ISO settings and image noise

ISO settings from 100 to 1600 in 1EV steps are available on the E-510. Like most current DSLRs, noise levels are low at ISO settings of 100, 200 and 400, but above 400 noise begins to appear, or if not noise then the effects of noise filtering (loss of detail) start to show. Complicating the noise picture of the E-510 a little is the fact that the user can select 4 different levels of noise filtering; Off (none), Low, Standard and High. With the standard noise filter set, there's a distinct loss of image fine detail at ISO 800 and ISO 1600 settings. If the noise reduction is turned off, image detail is significantly better, but the images are noisier.

The only camera I had for comparison was a Canon EOS 40D, which is also a 10MP camera, but has a larger (APS-C) sensor than the E-510. With standard settings on both cameras, the EOS 40D showed lower noise and somewhat finer detail, though a different lens was used (EF-S 17-85 on the EOS 40D, Olympus 14-42 on the E-510). Comparing a series of photographs at ISO 1600 using different noise filter settings with the E-510 and the standard EOS 40D image, the 40D image was still better in terms of both noise and sharpness. I thought the best compromise between noise and sharpness was with the noise filter set to "Low"

An example of exposures taken with the Olympus using the default noise settings is shown below. As you can see, the image degradation at ISO 1600 is as much due to smearing of detail by noise reduction as it is to the noise itself. These are 100% crops taken from a night image of a window shade.

Overall the noise performance of the E-510 is certainly acceptable, especially considering the smaller Four Thirds sensor size. At ISO settings up to 400, noise is low and sharpness is good. Even at ISO 1600 I think most users would probably be happy with small prints (4x6, maybe 5x7), though I don't think the images would stand up to larger sizes (e.g., 11x14).

Image Stabilization

Like Pentax and Sony, Olympus has chosen to use in-body image stabilization which works by physically moving the sensor to compensate for camera shake. The advantage of having stabilization in the body rather than in the lens is that it provides a stabilized system no matter what lens is mounted on the camera. Canon and Nikon have chosen to use image stabilized lenses. They claim an advantage in stability, but of course only a subset of their lenses have image stabilization, and it adds to the cost of those lenses. Neither Canon nor Nikon offer any fast image stabilized prime lenses in normal or wide angle focal lengths for example, while such lenses when mounted on a camera with in-body stabilization become part of an image stabilized system - and at no added cost.

It's clear to me that for most users, in-body stabilization is more useful than in-lens stabilization, even if it's not quite so effective. I say "even if" because I have yet to see any really hard evidence that lens based stabilization is better. In fact, the test results I've seen and I've obtained myself suggest that there really isn't much difference, at least with lenses of moderate focal length.

So does the image stabilization system work well on the E-510? My testing showed that indeed it does. When handholding the camera, on average I could get sharp images using a shutter speed 2 to 3 stops slower with IS on than with IS off. A few times I got sharper images at 150mm photographing at 1/15s with IS on than I got photographing at 1/250s with IS off (a 4 stop gain in stability)! The general rule of thumb, given the 2x multiplier of Four Thirds lenses, would be that you'd need a shutter speed of 1/300s or faster to be reasonably sure of sharp images. This is a very useful gain in stability, and I'll say again that since the stabilization is built into the body not the camera, it applies to any lens.

There are two IS modes. IS mode 1 provides both horizontal and vertical stabilization and is used in most situations where the subject isn't in motion. IS mode 2 stabilizes only in the vertical direction and is used when panning horizontally to track moving subjects.

Live View

Like most recent DSLRs, the Olympus E-510 has a Live View mode, allowing the use of the LCD as a viewfinder. In order to accomplish this, the E-510 must raise its reflex mirror. A single button on the rear of the camera enables Live View. In order to use auto focus, the mirror must be dropped down (losing the Live View display), AF achieved and the mirror raised back up. This process is not fast, taking from just under 1 second in good light to several seconds in low light where AF is slower. This means that Live View isn't much use for action photography. The LCD screen also blacks out for a second or two during the actual exposure.

Live View would be best used for studio photography or outdoor captures of static subjects. Despite the similarity to the LCD viewfinder capability of P&S digicams, it's really not a mode that a user should expect to use all the time. The normal reflex viewfinder enables much faster auto focus, subject tracking and a much higher frame rate.

In-Camera Editing

A limited amount of in-camera editing is possible. Images can be converted to B&W or sepia toned. Red-eye can be fixed, saturation can be adjusted and image size can be reduced. The edited images are saved as separate files with the originals left in place.

Flash

The EVOLT E-510 has a built-in flash, which pops up automatically in the program modes. In Manual, Aperture Priority, Shutter Priority and Intelligent Program modes the flash must be raised manually by pushing the flash button on the top deck of the camera. Like all pop-up flash systems it suffers from a lack of power and tends to produce red-eye, but it's no worse than most other DSLRs and sometimes any flash is better than no flash at all.

The flash guide number is 12 (meters at ISO 100) and in manual mode it can be operated at full, 1/4, 1/16, and 1/64 power. In auto mode flash bracketing is possible. Three frames are taken, one at normal flash power, one with lower power, and one with higher power. The steps can be set to 1/3, 2/3, or 1 stop of flash output. Flash exposure compensation from -2 to +2 stops (in 1/3 stop steps) can be selected via the menu system.

The flash is also used as the AF illuminator under low light conditions. It operates automatically in the program modes but must be popped up manually when shooting in P, A, S or M modes.

Olympus has several hot shoe mount flashes that are compatible with the E-510.

  • Olympus FL-50, $359. GN50 at 42mm focal length (meters @ ISO 100), zoom, tilt and swivel head, TTL Auto, Auto, Manual & Super FP Mode
  • Olympus FL-36, $195. GN36 at 42mm focal length (meters @ ISO 100), zoom, tilt and swivel head, TTL Auto, Auto, Manual & Super FP Mode
  • Olympus FL-20, $100. GN20 (meters @ ISO 100), lightweight, Manual, TTL Auto, and Auto control modes

The FL-50 has a faster recycle time than the FL-36, plus it can take an external high voltage power supply (HV-1), which provides even faster recycling and greater capacity for professional use. The FL-50 and FL-36 are also available in versions with built in wireless TTL operation (FL-50R and FL-36R)

Memory Cards

The E-510 has a card slot for Type I or II Compact Flash (CF) memory cards and compatible microdrives. There is a second card slot for xD-Picture Cards. You can store images on either type of card, but you cannot write to both cards simultaneously. Hi speed CF cards allow faster operation then xD-picture cards and are the preferred storage media. The xD card compatibility allows users upgrading form an Olympus digital P&S camera to continue to use their existing memory cards in the E-510.

Batteries

A 7.2v 1500mAh BLM-1 Li-ion battery is supplied with the E-510, which is good for 500 recharge cycles. A BLM-2 recharger (110-240v) is also supplied, which will recharge the battery in approximately 5 hours, which certainly isn't going to set any speed records. There is a faster battery charger available (BLM-1) which will charge the battery in two hours, but is still not super fast and costs around $70. If I was photographing with an E-510, I'd want at least one spare battery. There is also an available LBH-1 battery holder, which can be substituted for the BLM-1 battery and used to power the E-510 via three (non-rechargable) CR-123A lithium batteries. I suppose in a real emergency it might be useful, though CR-123A batteries aren't available everywhere, and if you're going to carry them with you, you might just as well carry a spare charged BLM-1.

Though Olympus do not offer any type of battery grip for the E-510, there are 3rd party grips available, which hold two batteries for extended shooting and provide extra shutter release buttons (see http://www.gadgetinfinity.com/product.php?productid=16832).

Mechanical Design

Though the E-510 uses the smaller 4/3" sensor, overall it's not significantly smaller than similarly priced APS-C sensor based cameras from other manufacturers. For example, at 5.3 x 3.6 x 2.7 in, it's actually slightly larger than the Canon Rebel XTi (5.0 x 3.7 x 2.6 in). This isn't necessarily a bad thing as cameras that are too small can be difficult to hold comfortably for those with larger hands.

Unlike some earlier Olympus Evolt models such as the E-330, the E-510 looks like a conventional SLR, with a pentaprism viewfinder (actually a pentamirror in the E-510) and a grip on the right hand side, which houses the battery and enables the camera to be held and operated using just one hand. The body is plastic, but the lens mount is metal and there is an internal metal fame.

Choosing a Lens

The E-510 is available as a kit with either a single 14-42mm f/3.5-5.6 lens or with both a 14-42mm f/3.5-5.6 and a 40-150mm f/4.0-5.6 lens. Given the 2x "lens multiplier factor" of the Four Thirds system, the 14-42mm lens give the same field of view as a 28-84mm lens would on a full frame 35mm camera and the 40-150mm gives the same field of view as an 80-300mm lens. For most casual amateur photographers these lenses would be perfectly adequate for almost all their needs. They aren't fast, so low light photography won't be easy, although the image stabilization system built into the camera body will greatly improve sharpness if these lenses need to be handheld at slower shutter speeds.

Both the 14-42mm f/3.5-5.6 and the 40-150mm f/4.0-5.6 are low cost lenses with lots of plastic parts, including the lens mount. Neither has a distance scale and of course neither has a depth of field scale. They feel quite well built, zooming is smooth and the "focus by wire" electronic manual focus ring is nicely damped although the "gearing" is a little slow, requiring quite a lot of turning to change focus distance. Even though the lenses are inexpensive, nevertheless both use ED glass to lower chromatic aberrations and the 14-42/3.5-5.6 also uses two aspheric elements to optimize image quality. Both lenses have the same 58mm filter threads and a lens hood is supplied as standard with both lenses.

Both the 14-42mm and 40-150mm lenses show slight vignetting when used wide open, but it's not really noticeable with most subjects. As would be expected, both lenses also show some barrel distortion at their widest setting which distortion reduces as the lenses are zoomed out. Chromatic aberration is very well controlled. Slight color fringing can be seen in the corners of images shot with the 14-42mm lens at 14mm, but you have to look quite hard to see it. Even at 150mm, the chromatic aberration of the 40-150 is very hard to detect. Given that the price of the Olympus Evolt E-510, 14-42mm and 40-150mm kit, $548, is only about $1 65 more than that of the Olympus Evolt E-510, $344, these lenses are great value. As long as you don't need a really fast lens, they're certainly worth owning.

Olympus has no fast normal prime lenses for their Four Thirds cameras. There is a 50mm f/2 macro lens, but on the E-510 it becomes a short telephoto, equivalent to a 100mm lens on a full frame camera. There is also a 35mm f/3.5 macro lens, but f/3.5 isn't fast. Sigma makes a number of Four Thirds mount lenses and their 24mm f/1.8 macro or Sigma 30mm f/1.4 EX DC for Olympus and Panasonic, $449, would make a good, fast, normal lens on the E-510.

Compatibility with Older Lenses

The Olympus DSLRs are not directly compatible with any of the older manual Olympus OM mount lenses, though an adapter is available that allows you to mount almost any Zuiko OM mount lens on the E-510. However, there is a snag. Olympus has some fairly serious restrictions on what apertures are recommended when using the adapter. For example, with the Zuiko OM 50/2 Olympus recommends only using apertures between f/4 and f/8, and with the 85/2 only apertures between f/5.6 and f/8 are recommended, which makes the use of fast manual focus primes pretty pointless. Olympus doesn't comment on what happens if you use these lenses at maximum aperture, but I'd assume that image quality must suffer.

Compared to the Olympus E-410

The E-510 is the "big brother" to the Olympus Evolt E-410, $380, which like the E 510 is available with lenses as the Olympus Evolt E-510, 14-42mm kit, $460 and the Olympus Evolt E-510, 14-42mm and 40-150mm kit, $548. The E410 lacks the sensor-shift image stabilization of the E-510 and lacks some of the control features such as dedicated buttons for white balance, ISO, AF mode and metering mode. It's slightly smaller (5.1 x 3.6 x 2.1" vs. 5.3 x 3.6 x 2.7"), lighter (375g vs. 460g), and cheaper.

Compared to Nikon, Canon, Pentax, Sony

In the same class as the E-510 would be the new Pentax K200D, $521, which also has a 10MP and sensor-shift stabilization built into the body, and the new Sony Alpha A200, 18-70mm kit, $484 (review), another camera with image stabilization built into the body. Both these cameras have the larger APS-C (1.5x) sensor, which may give them a slight advantage in terms of noise performance.

The Canon Digital Rebel XTi, $500 (review) (10MP), and the new Canon Digital Rebel XSi, $600 (review) (12MP), are also similar in features to the E-510, though neither has image stabilization in the body. Both depend on the use of image stabilized lenses such as the Canon EF-S 18-55mm f/3.5-5.6 IS, $124 (review). Both the Rebel XTi and XSi use an APS-C (1.6x) sized sensor.

A comparable APS-C (1.5x) camera in the Nikon line would be the Nikon D40x, $590 (review) (10MP), which like the Canon DSLRs requires a VR (Vibration Reduction) lens in order to stabilize the image.

Conclusion

With the Olympus Evolt E-510, 14-42mm and 40-150mm kit, $548, you get a pretty good starter DSLR Kit for a very reasonable price. The E-510 offers many features, not the least of which is image stabilization built into the camera body. This will definitely help to take sharper photographs. While the E-510 can operate in a P&S mode where the camera makes most of the decisions for the photographer, it also has an extensive set of manual control options, allowing the user to alter sharpness, contrast and saturation to their own taste, as well as control the amount of noise reduction applied to images and full manual control of exposure and focus. So while perfectly usable by a beginner, it gives room for the photographer to experiment with camera settings as they become more experienced.

The 14-42 and 40-150mm kit lenses perform well and cover a range equivalent to that given by 28-84mm and 80-300mm lenses on a full frame camera, which is the full range of focal lengths that the average user will need. If there is a requirement for shorter, longer or faster lenses, they are available from Olympus too.

The E-510 has a few areas which could be improved. Performance at high ISO settings (e.g. ISO 1600) shows noise and some image detail is lost. The camera has a tendency to overexpose brightly lit highlights and under sunny conditions this requires the use of negative exposure compensation if you want to prevent highlights from blowing out. This isn't helped by the fact that the default tone curve is a little contrasty and the overall dynamic range may be slightly lower than average for cameras in this class. AF is sometimes a little slow in dim light, which could mean missing indoor action photographs.

Where to Buy

Amazon.com offers the following Olympus EVOLT E-510 combinations:

Since no memory cards are included you might also want to consider getting a SanDisk 8GB, a 4GB, or a 2GB CF card.

Example Photographs

Olympus 40-150mm f/3.5-4.5 ED, set to 150mm (=300mm 35mm equivalent), aperture-priority at f8, ISO 200, Multi-segment metering. Sunny day, JPEG capture with default settings, no post-processing. Note that the white feathers on the chest of the geese are just blown out. The E-510 seems prone to this effect so it's worth taking a close look at the image histogram under conditions where you suspect this might happen and apply negative exposure compensation and/or reduced contrast when needed.

Taken with the Olympus 40-150mm f/3.5-4.5 ED at a focal length of 83mm (166mm 35mm equivalent) using an aperture of f/8 and an ISO setting of 100. Multi-segment metering. I used -2/3 stop exposure compensation here to prevent the white of the building from being overexposed. On a second photograph with no exposure compensation set, parts of the white building were indeed overexposed and so lost all texture.

This scene has no areas of white in direct sunlight and so is well exposed with no exposure compensation set. The Olympus 14-42mm f/3.5-5.6 ED was used, set to a focal length of 40mm and an aperture of f/8. The ISO was set to 100. Multi-segment metering.

Olympus 40-150mm f/3.5-4.5 ED, 63mm at f/7, ISO 100, no exposure compensation. Multi-segment metering. Another photograph taken in bright sunlight with a white object. Though the flag and sky are well exposed, the white flagpole is overexposed. This is another case in which setting a small amount of negative exposure compensation would be required.

Olympus 40-150mm f/3.5-4.5 ED, 50mm at f/5.6, 1/200s at ISO 100, no exposure compensation. Multi-segment metering. Aperture priority exposure.

Olympus 14-42mm f/3.5-5.6 ED, a night capture at ISO 1600. An exposure compensation of -1 2/3 stops was used for this image in order to properly expose the lighting in the store against the dark background. The inset at the top left is a 100% crop from the center of the original image and shows the noise level to be expected when shooting at ISO 1600. Noise reduction parameters were at their default value.

Olympus 14-42mm f/3.5-5.6 ED, set to 14mm, f/3.5 shutter-priority at 1/2s, ISO 800, minimal lighting conditions, JPEG capture, although not the ideal setup for low light photography, I experimented with a slow shutter speed to allow more color capturing of the lighting display and the multi-colored psyhoop. Although there is motion blur of the subject, this experimental type of photography could lend itself well to a variety of situations.

"The Evolt E-510 has a viewfinder that provides 95% coverage at a magnification 0.92x with a 50mm lens. The viewfinder image is quite small, though perfectly usable in my opinion."

As Mike Johnston has noted, "the [film] convention was to give the magnification of 35mm camera viewfinders with a 50mm focused at infinity. Unfortunately this number doesn't translate directly to smaller formats such as reduced-size digital sensors, because the angle of view with a 50mm is not the same. To get a useful comparative number, you have to divide by the magnification factor of the sensor. Thus, a Canon camera that has a ".80X" viewfinder would have to be divided by 1.6, giving a magnification of .5X.

So, .92X on a 4/3rds camera needs to be divided by 2, so the "real" comparative number is... .46X -- which explains why it seems small despite 'high' numbers.

I am happy to see in photo.net a review of a current Olympus DSLR, and a good and generally balanced one. However, there are a couple of sentences that may leave a wrong impression about the use of the camera.

It is true that it is difficult to switch focusing from AF to MF through the menus. What it is not clear from the review is that there are other very effective options: 1) dedicated AF button (right arrow). Pressing this button and selecting the desired mode with the thumb-wheel. 2) Pressing "ok" botton and quickly navigating the control panel, and then using the thumb-wheel. However, both of these options force you to take your eye away from the viewfinder. I normally set the E-510 to S-AF+MF mode. In this way the camera auto-focuses by half pressing the shutter release, and while still keeping it half pressed I can fine tune the focus just by turning the lens focusing ring.

It is also true that the menu system is a bit awkward to use, mainly because the E-510 does have so many parameters that can be customized. However, one rarely needs to use the menus during a shooting session as the "control panel" and direct access buttons give access to all the most frequently used settings.

caveat: I am the happy owner of a E-510, but I have not used other DSLRs. I have used film SLRs for many years.

The metering system actually measures light reflected off the focusing screen. Because AF focusing screens are brighter than the old matte screens for manual focus (so that they are usable with slow consumer zooms), a metering offset must be introduced when using fast (faster than f4) lenses.

If you attach a Zuiko lens to the E-510 (or a 1975 K-mount lens to a Pentax DSLR), and the MF lens is faster than f4, the camera will consistently under-expose because there's so much light. With a fast AF lens, the lens can report its aperture to the body, and the metering offset is automatically dialed in by the body.

On Pentax at least, there is a consistent 1.5 - 2 stop underexposure at f1.4 to f2, around 1 stop at f2.8, and metering is correct between f4 and f8. Above f8, the camera begins to over-expose.

I suspect in Olympus' case, they sidestep the whole issue and require that the MF lens is only used at those apertures where no exposure errors will occur.

Although I cannot see why anyone would want to do manual focus on the tiny Olympus screen. I use a K10D (which has a larger screen than the Canon EOS 40D) and I still got a split-image screen for it to make manual focusing not such a chore.
