I wonder if we get an increase in the "why are my photos shaky" questions when people start using liveview.
Live view promotes bad photo techniques. It chews through batteries in a camera which could otherwise take hundreds of frames and easily be left on an entire week without too much concern. Delay between what is happening and what is seen on the screen You have a limited latitude for what you can display on the screen in live view, try pointing it at the sun and see how much you can see of the frame. Some people don't like the 'gimickiness' of Live View DSLR cameras.but others seem to like it.īig Mike mentioned the different autofocus that needs to be used for liveview since the mirror isn't reflecting part of the image to the AF module in the bottom of the camera, but what was not mentioned is the massive performance hit you suffer from this AF technique as opposed to the very advanced phase detection system in modern SLR cameras. I believe that the newer Nikon cameras can do it either way. Some models will flip the mirror down to quickly auto focus, then flip up again.and other models use the same AF technique as digi-cams.and read contrast differences in the digital image. Also, typical SLR cameras use the mirror reflection for autofocus, so when the mirror is up.the AF needs to be accounted for. This creates a few issues.you can't use the viewfinder at the same time. In Live View mode, the mirror flips up and the shutter opens, allowing the sensor to see the light and create the digital image on your screen. Digicams get around this because they don't have an actual shutter and the sensor is always getting light.Īs mentioned, 'Live View' is the newest craze to hit DSLR models.many of the newest ones have this feature. The image sensor is covered by the shutter, so even if the mirror was not there.the shutter would still be closed. Also, the simple fact that the camera has an actual shutter, is an issue. While the L in SLR is for lens.the R is for reflex, which (I assume) means that there is a mirror and that mirror is the the path of light and needs to flip up before the shutter opens.
