Want to expand my photography a bit more and get back to the roots of it. I decided I want to shoot film and pick up a Nikon Fm2 for that old classic feel. ...
If you have Nikon FX size autofocus lenses they will work for film. Get any of the film AF bodies. The last one I bought is the N90. It has color matrix metering and AF and it will work with manual lens. It is pretty much a Nikon D600 that takes film. Pick one up used for not a lot. The N90 also has a pop-up flash with TTL metering that is not do much different from the curent iTTL system. Fill flash is good to have
The Fm2 is not bad but the older cameras are so cheap you can afford a "pro" body. Buy an F2 or an F3. The F4 is really better but like the N90 has a modern "feel"
A good compromise bofy is the N2020. If was Nikons first AF body and it works well with both MF and AF lenses and still looks like and older body. The best part is they sell used for about $35
All that said. I just don't see the point of shooting 35mm film. If you are going to shoot film buy a medium format system. Then rather then having a nostalgic toy you can actually do things your Nikon dSLR can't
Medium format need not be expensive. Buy a Yashika mat 124G for about $250 and get quality better then any Nikon. The reason is that the size of the medum format negative is much larger than 35mm. Not only is the film grain much reduced but the tones are so much smoother.
