Does anyone think that the F100s standard back -with the lock for the AF selector - would work on an F5??? I have a tendency, as I am left-eyed, to bump the AF selector with my nose and find it very annoying. However, if I use the F5's AF sensor lock and need to change the sensor quickly, it takes too long to do so. The system on the F100 seems better suited to speed changing. I am curious if the F5 will be able to utilize this new back. Any ideas on the feasibility of this??? -Michael ************************************************************************* Palmieri Photography Michael L.
