In short, current sensors and lens-systems are very close to being up to the task of replacing the film-era mirror & prism, but have a few remaining limitations that, for some shooting conditions, make the SLR worth the extra size of both the body and the lenses. I'll add that I thought up-to-the-eye viewfinders were a film-era throwback, until my eyes ...

When you look at technology you can not decide better by just taking into account what is newer. New != Better What you need to do is take a look at the overall architecture. In the case of the SSD versus the harddrive its undeniable that a SSD has a better overal architectural design. Its not a question of mechanical versus electronic components per se ...

Also consider low light and long exposure scenarios - at ISO 100 f8, the live preview is going to show you a pitch black screen - which makes it pretty difficult to frame and focus! Your eye through a viewfinder of a SLR or SLT is still going to be able to see the scene, even if you are relying on distant street-lights to accurately focus

Perhaps it's that I wear specs and can only see the end of my nose, but isn't one of the most obvious advantages of an optical view finder that you can actually see the image in daylight? I'm a D80 user, and I've stood behind others with their smart phones and point & press cameras and looked at their screens. It's just a black shiny square. You ...

Also there is problem, that the LCD on the back of camera does not have the resolution of main chip. So it shows you inaccurate image in much lower resolution, than would be then taken. Also the range of LCD values (from totally dark to totally light) is lower than the chip have - so another source of inaccuracy - naked eye is much better then cameras/LCDs ...

Another disadvantage of using the sensor to generate a near real time preview in lieu of an optical viewfinder is the requirement to keep the sensor energized continuously. In addition to the increased battery usage, over extended periods of time this tends to build up heat which, as we all should already know, can affect read noise and thus the ...

Don't forget a major drawback that EVF's require power to compose, and are much harder on batteries if you spend a lot of time with the screen on. Also, as previously mentioned, because of delays, it is harder to follow moving objects with an EVF.

And with a digital camera, you don't need a hinged mirror as you can show the user exactly what light will be captured by just routing the sensor output to an LCD display. This is the reason for the rise in popularity of mirrorless interchangeable lens cameras (MILC). Without the mirror box, the camera can be smaller, lighter, less expensive, etc. ...

Is there any significant benefit to having an SLR mechanism in a digital camera? Particularly in terms of a benefit that's large enough to make up for the liability of adding a mechanical part into a design where a solid-state alternative is available? Yes. Response speed for both autofocus and shutter release. The mirrorbox has a number of side ...

Ok, I see the problem you're talking about - but only just. My first impression is that the diagnosis from Nikon is quite plausible. My second thought is that the reason you don't see the artefact in still is because it possibly only is visible if you drastically underexpose the shot like you did in the video. Try taking a correctly exposed shot of a pale ...
