I had not really noticed this before, but there seems to be a bit of wobble or play on the film advance lever of my F. Is this normal? Is this a sign that something is wrong? This is the only F I have, so I can't really compare it to any other. I am hoping other F owners in here will chime in and tell me if this is normal or not. My F2A, F3, and other Nikon SLR's don't have any play or wobble at all. Also, I noticed that it does not wind smooth all the way through. If feels somewhat slippy as I wind the lever. Does this mean that I probably striped a gear or bearing? So far I have not had any problems with the winding mechanism. Even the meter works on this F (FTN Metering head). I just want to know if I need to send it to the repair shop or if this is what F's are supposed to feel like.
