Why are my Ax photos so dark at high shutter speeds like 1/16000 sec (available on A1 only)?
See the FAQ on shutter-aperture for an explanation of exposure. 1/16000 sec is a very fast shutter speed. Even 1/4000 sec is a pretty fast shutter speed. Even with a wide aperture like f2.8 that lets as much light as possible through the lens, you need very bright light for a shutter speed of 1/16000 sec to provide enough light to the camera’s CCD sensor to produce a properly exposed picture. Chances are you will hardly ever be able to use a very fast shutter speed like 1/16000 sec, if at all. If you thought you could use 1/16000 sec shutter speeds to freeze sports action, you will be out of luck, unless you are shooting a game on Venus or Mercury!
