Don't worry. You're not the only one. If my Nikon F2 (I'm the original owner, from the early 70s) finally bit the dust, I'd be on KEH like lightening to find an identical model. That camera has become like an extension of my hand. Change even one millimeter on it and I would probably trip, fall, and crash and burn from the resulting instability.

A fun question I've asked others before: If you suddenly look up and find yourself being charged by a rhino... QUICK!... which way do you rotate the manual focus ring??

If the person answers only with words, that camera is not a hand-extension for them. But if they answer by first raising their hands to their face and pausing momentarily to see what their fingers tell them, you'll know you've found your answer.
