Besides the fact that there is no cable release socket the other thing that bothers me about the F100 is lack of mirror lock up. I have heard that this will be a problem with shots on a tripod with a telephoto lens at 1/30 and slower. BUT, I have also heard that the shutter in the F100 is so good that there is no need for MLU. So which is true? Or are both true to some extent? And what can I do to ensure sharp photos with the F100 and my 80-200/2.8?
The lack of MLU on the F100 affecting sharpness is largely urban legend. Shot quite a bit a few years back with one using the 80-200/2.8AF and 300/2.8AiS and never detected any softness at lower speeds I could pin on mirror slap. Had very similar results with the older N90s, another MLU-less body.
