Why are SLR mechanisms still prevalent among high-end digital cameras?

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 ...

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 ...

Why is Live View so noisy and unlike mirrorless shooting?

On a DSLR, when you use the viewfinder, the mirror is lowered, and a secondary mirror reflects some of the light to phase-based AF and exposure sensors at the bottom of the camera. These are accurate ...

Is something wrong with my camera display?

In order to use the rear LCD to compose pictures (as opposed to using the optical viewfinder), you must put your camera into "Live View" mode. On the 600D (and all other recent Canon SLRs), this is ...

Why does my Canon 600D take pictures in live mode but not in viewfinder mode?

It seems like you have mirror lockup enabled. The first full press of the shutter button will cause the mirror to move up (just as it does before taking a normal photo using the viewfinder) but the ...

Disable Liveview timeout

It is not that the display switches to viewfinder after some seconds, it is that the camera goes to sleep mode. So you need to go to Menu, then look for the Auto Power off option, and choose the ...

Is it normal that a 40D produces a continuous noise in Live View mode?

With some image stabiliser lenses this is normal. Just like when you hold the trigger half pressed, the IS keeps running. If the IS motors are audible, the noise will come from the lens continuously.

Why is live view so dark when I'm shooting with strobes?

You need to turn off exposure simulation in live view. Exposure simulation can only show you what the image would look like without flash, because the flash burst isn't in the scene until you take the ...

What's the point of a shutter when the sensor is clearly working all the time to provide live view?

On the screen at the back of the camera, a preview is constantly shown. I assume this preview is made by light hitting the sensor constantly. So this must require the shutter/aperture to be ...

Why is Live View so noisy and unlike mirrorless shooting?

It's because on a (Nikon) DSLR, live view is part of the video stream with rolling shutter. This stream is usually not in a raw format and is typically reduced resolution. Some Nikon's have a "silent ...

Why is it harder to focus using LiveView?

This is the difference between CDAF (contrast detection) with integrated PDAF hybrid pixels vs full PDAF(phase detection). When using live view, the camera's imaging sensor is exposed and it tries to ...

The LCD is blank with my 500mm/F8 Nikon mirror lens on my Nikon D200 when I shoot

You can't, the Nikon D200 is too old to be able to read the sensor in realtime in order to show you the image on the LCD screen. That feature was introduced with the D300 / D90
