Here are some high iso test shots with the nikon d4 and d800, unfortuantly just the jpeg which will have some noise reduction already added. Here i inspect the noise at iso 12400 on the d4 and also its rediculous h4 setting and also its video with auto iso enabled.
this is just a quick upload of the raw footage captured from the nikon d4 dslr, it was set in auto iso and it constantly changed, here the camera is equipped with the nikon 24mm f1.4 pro lens and although it constantly autofocuses there are time when i had to press the AF button to get it to refocus. it seems to have a mind of its own some times. otherwise impressed. the body is really good though. holding it it felt really nice, nicer than the d3x and far nicer than the d800. more commentary on this in the next video
