Difference between Mirrorless and Point & Shoot camera?

<p>Hello<br /><br />I know how do work DSLR and Mirror-less but I don’t about compact camera <br /><img src="http://s30.postimg.org/st3vm69vl/Flange_focal_distance_2_types_camera.png" alt="" data-url="http://s30.postimg.org/st3vm69vl/Flange_focal_distance_2_types_camera.png" /> <br /><br /><img src="https://www.imageupload.co.uk/images/2016/01/07/NX10isacamerathatbreaksnewground-notwithitsmirror-lessdesignoritscompactsize.copy.jpg" alt="" data-url="https://www.imageupload.co.uk/images/2016/01/07/NX10isacamerathatbreaksnewground-notwithitsmirror-lessdesignoritscompactsize.copy.jpg" /> <br /><br />would you tell me compact camera Difference with figure ?<br /><br />thanks</p>

<p>Compact point-and-shoot cameras are just smaller mirrorless cameras, and in most cases you cannot remove and change the lens. There are too many different styles and prices to describe them all as if they were the same. For example, an iPhone is also a compact mirrorless camera. So is a GoPro. But they are very different in terms of their intended use.</p>

<p>All cameras other than reflexes are without mirrors in the light path: but the term "mirror-less" is applied generally to cameras whose lenses are interchangeable.</p>

<p>Mirrorless cameras of interest to advanced amateurs and professionals generally have interchangeable lenses (ILC) and an eye-level electronic viewfinders (EVF). There are exceptions. The Leica Q, for example, has a fixed 28 mm lens. It compensates by having a very good lens and producing high quality images. The sensors are larger than those of a compact camera, typically micro 3/4 (half frame), APS-C (2/3rds frame) or Full Frame. The prices is typically $1000 or more.</p>

<p>Compact mirrorless cameras usually have a fixed lens, and are pointed using an LED rear screen, at arms length. Some have an optical finder, but usually not a very accurate one. The sensors are usually small, resembling those used in small video cameras. The price is typically less than $1000.</p>

<p>Technically I think it's an abbreviation of "mirrorless system camera", the system being the interchangeability of lenses and the availability of other parts to add. Most mirrorless cameras use the same sensor as a dSLR and thereby gain the advantages of that, including quality images at higher sensitivities making indoor photography more practical.</p>

<p>A compact camera has a non-removable lens, and usually (there are a few rare exceptions) a much smaller sensor. I've seen the cheapest compact cameras be out-performed by a good cell-phone camera module, while some of the highest-end ones use a sensor nearly as large as a 4/3rds camera (actually the same size as Nikon's mirrorless system line, which might explain a lack of respect for those) and cost like a dSLR.</p>

Mirrorless camera is that don't have interchangeable lenses are often referred to as compact or point and shoot cameras,

and many people reserve the word mirrorless for cameras without mirrors that have interchangeable lenses. That's not

really the technical definition, it's just common usage. In many cases the difference mostly comes down to whether the

camera has a fixed lens or a mound and interchangeable lenses. For example, there is not A heck of a lot of difference

between a Fuji X100 and a Fuji X-Pro1 aside from physical size of the camera body and the fact that the X100 has a fixed

lens while the X-Pro1 has a mount for Fuji X mount lenses. Many people only use the term point and shoot for cameras

that do not have manual control features. So a Fuji X20 would be a compact camera, but not a point and shoot.

Panasonic LX100 has a micro 4/3 sensor (but an odd configuration that does not allow the entire sensor to be used in any

mode, always applying a crop to the image) but a fixed lens and does he have manual controls. Some people refer to that

as a mirrorless, others do not, though by the technical definition of mirrorless it is one.

<p>The first time I came across the term "mirrorless" was some years ago, when the idea of a camera the equivalent of a conventional DSLR but without a mirror box was in it's infancy. Soon there were mentions of "Mirrorless DSLR's", a system camera with interchangeable lens and various other typically DSLR accessories. I guess we have to move away from this nomenclature since the word "reflex" implies focusing and composing on a screen of some sort via a system of mirrors, but the contemporary EVF's give cameras like the Sony A7's a distinctly DSLR appearance and feel, along with equivalent operating systems. With the interchangeable lenses and all the other bits and pieces that these systems offer, to me these cameras are pretty much "Mirrorless DSLRs"!</p>

<p>Indeed, there are several. You mentioned the Leica, but don't forget there are other leica fixed zoom lens mirrorless and the Panasonic LX1, most likely basically the same camera only without the dot and the price. Also the Ricohs are very good fixed lens/fixed focal length cameras as are the Fuji X-100 series cameras. And I'm not even familiar with the Sony and Olympus versions. Then there are several fixed lens excellent film cameras as well. Leica's, Contax, Richoh, Hexar, Canon, Nikon, Olympus etc. Most not made any more but many of these are still used by very serious photographers. All rangefinder cameras are "mirrorless". Do people consider rangefinder cameras to be mirrorless? I do in general, but I think technically an optical rangefinder does have a mirror in it.</p>

<p>I like Sean Reid's term for high-end mirrorless camera - EVC, or Electronic Viewfinder Camera. While Leica M's are mirrorless, they operate with a different principal, having an optical finder with a mechanical rangefinder from another time and place. Using this definition, Reid also excludes cameras with only a rear LCD.</p>

<p>If one used the $1000 threshhold, then the simplest Leica P&S would qualify. Personally, I would exclude those, even the digital M cameras, but probably keep the FF, fixed lens Q.</p>

<p>Yeah it will depend on what you consider "high end mirrorless". I think the Leica T has an EV as well. I believe the Fuji X100 series are hybrid with both an optical viewfinder and and an EV. I think mine is a bit broader than yours.</p>

<p>A full-time, eye level electronic viewfinder and interchangeable lenses pretty clearly defines a camera which would attract a serious photographer. There are professional photographers who make a point of using cell phones, others 8x10 view cameras (which happen to be mirrorless too). Exceptions don't really define the marketplace, however.</p>

<p>It's fair to say that the Leica T, with an EVF and interchangeable lenses falls in the high-end mirrorless category. I'm not convinced about the Fuji X100, which has a fixed lens and retails under $800 at current prices. Its hybrid viewfinder is widely regarded as a net negative asset*. The Fuji X-T1 has a full-time EVF and interchangeable lenses, starting at $1500, makes the cut easily. The controls follow a very traditional pattern and there is an excellent stable of lenses, making it a popular choice among serious photographers.</p>

<p>* The EVF takes over at the moment of exposure, temporarily blinding the viewfinder.</p>

<p>Says who?</p>

 

<p>It works for me, and seems to agree with accepted conventions. You are welcome to your own opinions and I to mine.</p>

<p>I appreciate your devotion to rangefinder cameras. I went that route for over 40 years, and again last Summer with an M9. To me, the issue is the viewfinder, not the absence of a mirror. Among other things, an EVF makes it easy and accurate to use lenses outside the 28 to 90 mm window, and to frame accurately throughout.</p>

<p>I'm not devoted Edward, my main camera I'm using is a GX7, EVF and touch screen. I'm a big fan of the new EVF's. I was just questioning your parameters. But I agree, we can both hold our own opinions and it probably won't matter a whit.</p>

<p>I like your postings in the Leica forum. That's why I took you for a rangefinder guy. Cheers.</p>

<p>Thanks Edward, come by and post photos when you can.</p>
