Going back to your original question, is there a feature or function that one can't do given a particular shooting requirement?
For instance do you need the F2's MLU to minimize camera movement or the New F-1's autoexposure mode in fast shooting conditions? Given the specific conditions, maybe it's a case of horses for courses and you need both.
Yep, that's right. Of course, when I want a perfectly still camera for a tack sharp image, I usually go to the RB-67 and a tripod. Now that I think about it, I don't think I've ever used the MLU on any of my Nikons.
