alanbrowne Posted November 25, 2008 Share Posted November 25, 2008 I've done a review of the a900 here: http://aliasimages.com/Sonya900Revue.html It includes the following firmware implementable improvements that I believe will make the camera that much better than the great camera it is: 1. When in MLU drive mode, allow the Remote Commander to control the shutter. 2. 2 second shutter delay - does not immediately raise the mirror. 2 second shutter delay should always (as in past Maxxum/Dynax cameras): -Raise the mirror -Delay 2 seconds -fire the shutter 3. Exposure compensation, whether in the main display when selecting the compensation sub-window or on the exposure compensation display: -Front dial: reflected (ambient) light compensation. -Rear dial: flash compensation 4. Preview should allow ISO adjustment and zooming in on detail. 5. MLU time-out. 30 seconds after the MLU is fired, the MLU is cancelled if the shutter is not depressed again. -Add a menu option to fire the shutter (take the image) after the 30 second time-out. 6. Add option to record raw files in Adobe DNG format in lieu of ARW. 7. Add non-resettable counters accessible via the menu. Shutter releases Images recorded Embed the above data in the EXIF data. 8. Tethered shooting: show images on PC/Mac immediately as they are shot. Cheers, Alan Link to comment Share on other sites More sharing options...
paul_de_ley Posted November 25, 2008 Share Posted November 25, 2008 Nice summary Alan! A small note viz 2 sec MLU in previous alpha models. I don't have an a900 myself, but I can confirm that with the a100 the 2sec MLU really lifts the mirror 2 sec before opening the shutter. It would be very counterproductive indeed (as in: brainless engineering) if the a900 doesn't do that. Can you actually release the shutter without a lens to confirm that the mirror stays down until right before shutter release? As to improvements needed for the next firmware version: my personal single biggest one would be full shutter unlock & focal length programming functions to allow steadyshot to work with any manual focus lens that can be physically adapted onto alpha mount. As far as I understand, the a900 currently provides neither shutter unlock nor focal length entry? Of course if it really lacks shutter unlock then you can't really check the exact sequence of 2 sec MLU action of the body alone. And an aside: do you happen to know of any full reviews published to date in a print photo magazine? I don't subscribe to any but have been scanning store shelves for the past two months and found none sop far. The November issue of ProPHOTO Magazine has a one-page preview-like writeup in their November issue, right before one-and-a-half page about the Canon 5D MkII. They are pleasantly positive about the a900 but not really providing any factual test results. Link to comment Share on other sites More sharing options...
peterblaise Posted November 26, 2008 Share Posted November 26, 2008 . Notably, PopPhoto magazine's full review this month (pages 80-86, December, 2008) used the word "annoyed" that you can't save the preview picture. Who ever thought of a camera taking a picture that you can't save? Only from the mind of ... SONY! Argh! I can't recall any Minolta camera every garnering an "annoyed" review, especially NOT the Minolta Alpha/Dynax/Maxxum 9 that this camera is supposed to be the decedent of! PopPhoto did conclude, however, that this full-frame camera is a candidate for their camera of the year (resolution, viewfinder, ergonomics, price), along with my favorite, the Panasonic Lumix DMC-G1 micro four- thirds half-frame DSL/EVF that has real knob controls like the Minolta 9, by the way! Sony missed this? Alan, the 1985 Minolta Alpha/Dynax/Maxxum 507si/600si/650si reintroduced direct input/direct readout knobs (especially for drive mode, exposure mode, metering mode, exposure compensation, and flash compensation) that were then implemented in the subsequent 9 and 7 models (and some of which are also implemented in the Panasonic Lumix DMC-G1 - did they hire former Minolta engineer photographers or at least buy and use Minolta 507si/600si/650si/9/7 cameras? Panasonic is buying Sanyo, and Sanyo used Konica Minolta lenses ...). Thanks for the review, Alan. Why not put the facts into http://www.camerapedia.org/wiki/Sony ... and the opinion into a talk page behind your fact's page, and grow the Alpha resource there?

Then there’s that incredulous top information screen which doesn’t do a flagship model any favours. All are odd decisions and omissions given Sony’s reputation as an electronics giant and gadget leader...Then again you may not care for modern gadgetry on a DSLR and find Sony’s approach with the A900 refreshingly traditional..." .

ilkka Posted December 1, 2008 Share Posted December 1, 2008 I think recent Amateur Photographer (a UK magazine) had a test of A900. I did not see the actual article but they have usually quite good tests. One can be annoyed with the preview image but if it is so important to be able to save it, why not just make an image and review it? Then either keep it or delete. For some reason Sony could not get live view built in so they came up with this alternative. It should be okay for studio still shot use and I cannot really imagine many other places where I would like to use live view anyway. If that was the only thing they were annoyed about, I suppose it speaks very well of the camera. Some comments to the original list of improvements: 3- I always set it so that front dial controls aperture and rear dial expo compensation. I rarely use flash and don't really care how to set compensation for that. I only hope it is not something that can easily get on the way of normal operation. 4-Not sure how much detail there is in the preview image. I don't think it is a full size image. If you need to zoom in, it may be easier to just make an exposure and then zoom. What do you want to achieve by adjusting ISO? Exposure compensation? The camera can hardly estimate noise in a preview image. 6-This should be an option in every digital camera on the market. Sadly it is not in any.

peterblaise Posted December 1, 2008 Share Posted December 1, 2008 . Earlier: "... One can be annoyed with the preview image but if it is so important to be able to save it, why not just make an image and review it? ..." ... because the purpose of preview it to see the effects of adjustment, which Sony DOES offer - you can play with exposure and other settings and see the effects before taking the "real" shot. We cannot equally play with the exposure and other effects on an already captured shot, but great suggestions for Sony to offer that feature, too - to adjust and resave an existing shot on the card - even if from a different camera - Photoshop in-camera! ;-) Nikon does. We're just miffed that the camera doesn't save the test preview. I presume it's a quick, un-de-Bayered 1/2 dimension capture (2-dimensional 1/4, or 4:1 Raw conversion requires no time- and resource-consuming de-Bayering), but what if the subject scene changes in the meantime and cannot be duplicated? Lesson: always carry a pocket camera to shoot the LCD preview on the back of your Sony Alpha DSLR-A900 so you can actually permanently record and save the preview picture that's about to be lost forever! Argh! The Panasonic Lumix DMC-G1 live view preview even shows ISO and shutter speed change effects by blurring motion in the preview - all dialable in, including showing it realtime through the viewfinder. It's a half-frame 12 megapixel camera, sort of like half of a 24 megapixel full frame camera, but it gets many things right that Sony does not, that Minolta used to get right (like direct input and readout knobs), like full preview (in Minolta's DiMage DSL/EVF series), and with a lens, the Panasonic G1 is less than 1/3rd the cost of the Sony A900 without a lens. Half performance, one-third cost - cool! . Link to comment Share on other sites More sharing options...
peterblaise Posted December 1, 2008 Share Posted December 1, 2008 . Looking at the Sony CyberShot DSC-R1, I see a humongous top with - viewfinder, - flash, - AND pop-up-rotatable LCD. So ... so I see NO REASON why Sony could not have also included an on-board flash with wireless remote control of accessory flashes into and on top of the Sony Alpha DSLR-A900, along with it's mere (by comparison to the R1) pentaprism and viewfinder. Frankly, Sony could even have included a rotatable LCD in the A900, now that I re-look at how nicely done all these features are integrated into the the vintage Sony R1. http://images.google.com/images?hl=en&q=sony+dsc-r1&btnG=Search+Images&gbv=2 or http://tinyurl.com/5ls944 Dang. .

peterblaise Posted December 2, 2008 Share Posted December 2, 2008 . Wow, the Nikon D3x 24 megapixel version is $8,000 - the Sony Alpha DSLR-A900 at $3,000 is lookin' good! (The Nikon, to be honest, has some very, very desirable features, and is most unarguably WORTH the price ... of 2 1/2 Sony Alpha DSLR-A900 cameras?!?) http://www.calumetphoto.com/item/NZ24031/?t=CM01&a=CM01 or http://tinyurl.com/6xywwx Nikon D3X 24.5MP Digital SLR Body Mfg. Part # 25442 $7,999.99 Product Features The D3X is an FX-format digital SLR featuring extreme 24.5-megapixel resolution and superb low-noise capabilities, which provides professional photographers with commercial-quality image performance. The foundation of the enhanced performance of the D3X is its FX-format, 24.5-megapixel (6048 x 4032) CMOS sensor providing commercial, high fashion, fine art and landscape photographers with the extreme resolution, dynamic range, color depth, detail and sharpness that clients demand. The large 5.49-micron pixel size and high signal to noise ratio produces vibrant images with breathtaking image fidelity while reducing lost highlights and shadows, and ensuring smoother tone reproduction with minimized noise. Image files can be recorded as TIFF, JPEG or NEF (RAW) formats in either 12- or 14-bit compressed or uncompressed formats, and recorded to UDMA compatible CompactFlash cards for optimum speed. Photographers can save image files directly to the dual card slots as overflow, backup, or as separate file formats to different cards. Building on the D3X's flexibility, users have the creative option to shoot in the 5:4 crop mode with 20.4- megapixel resolution, the ideal format for creating 8 x 10-inch portraits. While using DX-format lenses, faster continuous shooting of up to seven frames per second can be achieved at a resolution of 10.5 megapixels. Just like the D3, the D3X achieves a start-up time of a mere 0.12 seconds and a shutter release time lag of 0.04 seconds. The exceptionally low noise of the D3X is essential to any professional commercial application, and it provides photographers with an ISO range of 100 to 1600, expandable to 50 (Lo-1) and 6400 (Hi-2). The ultra smooth tones and lack of grain at ISO 1600 as well as at low sensitivity settings result in smooth, natural skin tones and exacting detail that, before the D3X, required larger and far costlier studio-bound camera systems. The D3X also features Nikon’s exclusive Scene Recognition System, which continuously analyzes information from the 1,005-pixel RGB light sensor, to further refine auto exposure, auto white balance and autofocus calculations. Nikon's exclusive 3D Color Matrix Metering II helps ensure accurate exposures, even in the most challenging lighting conditions. Active D-Lighting, used in combination with 3D Matrix Metering II, helps to determines proper exposure, and creates realistic contrast while compensating for lost shadows and highlights. Additionally, the D3X features Nikon’s exclusive Multi-CAM 3500FX focus module, with 51 AF points, 15 cross type sensors and 36 horizontal sensors that easily track and lock onto moving subjects, delivering fast and accurate AF performance. Users can select any of the AF points, making it easy to consistently attain accurate focus right on a subject’s eyes, frame after frame. AF is also available in one of two Live View modes. This feature allows the user to zoom in up to 27x on the LCD screen to ensure critical focus. A bright and accurate viewfinder offers 100 percent coverage with 0.7x magnification. The body also houses Nikon’s acclaimed 3.0-inch super density LCD screen, now relied upon by so many photographers. The high-resolution 920,000-dot screen is viewable at wide angles up to 170 degrees, and will allow photographers to quickly zoom in to confirm critical focus. Users can also output the video signal to an external display via HDMI to allow client viewing. Thanks to incredibly efficient internal circuitry, the D3X can capture up to 4400* shots per single charge of the camera’s Lithium ion battery. Features: - Extreme resolution 24.5-megapixel FX-format (35.9 x 24.0mm) CMOS sensor - Large 5.49µm pixels capture astonishing detail and subtleties with outstanding dynamic range for demanding commercial applications. - Nikon EXPEED image processing technologies - EXPEED extends and assures breathtakingly rich image fidelity and reduces noise, even at high ISOs. - 138 MB* Processed NEF (RAW) 12 or 14 bit image files - Selectable bit depths of 12-bit (4,096 tones) or 14-bit (16,384 tones), both yielding incredible image quality through a 16-bit processing pipeline, for smoother tonal gradations. - Low noise ISO sensitivity from 100 to 1600 - Added ISO settings of Lo-1 ISO 50, Hi-1 ISO 3200 and Hi-2 ISO 6400 extend versatility. - Two Live View shooting modes - Two Live View modes add flexibility, and up to 27x magnification in the Tripod Mode, acute focusing accuracy is easily confirmed. - Continuous shooting at up to 5 fps at full FX-format resolution - Commercial image quality teams with speed and handling to create new shooting possibilities—in the studio or on location. - Fast, accurate 51-point AF system - AF system features 4 Dynamic AF modes, including 3D Focus Tracking, for autofocus precision and razor sharpness. - 1,005-Pixel 3D Color Matrix Metering II with Scene Recognition System - Two Nikon-exclusive technologies provide intelligent auto exposure capabilities, along with refined auto white balance detection and faster, more accurate AF performance. - 3-inch super-density 920,000-dot VGA LCD monitor - Individual factory calibration assures the color accuracy of each D3X monitor for critical image review. - 100% viewfinder coverage - Nikon Picture Control - Four preset options: Standard, Neutral, Vivid and Monochrome, and 9 customizable settings provide advanced, personalized color control. - Rugged, durable and precise magnesium-alloy construction - Effectively protected from invasive dust, moisture and electromagnetic interference with a self- diagnostic shutter mechanism tested to 300,000 cycles. - Dual CF card slots with overflow, backup and copy options - Virtual Horizon Graphic Indicator - Up to 4,400 images per battery charge Item Includes: - D3X Body - Rechargeable Li-ion Battery EN-EL4a - Quick Charger MH-22 - USB Cable UC-E4 - Audio Video Cable EG-D2 - Camera Strap AN-D3X - Body Cap, Accessory Shoe Cover, and Eyepiece - Battery Chamber Cover - USB Cable Clip - Software Suite - Supplied accessories may differ depending on country or area .
