hey guys, i'm in new york city for a quick visit and went out to times square to do some shooting. well, when i use my shortest lenses (58 and 80) which require the front standard to be mounted on the inner most rail, i found that there is a lot of movement. it seems as though the inner most rail - the one with the internal focusing mechanism - is not securely attached to the camera 'box'.

is this a quick fix? i couldn't find any obvious screws to tighten.
if not, where in the city can i have this repaired... i'm staying just off times square.

thanks for any help!!!
scott
