Thanks for the heads up Shepherd.
The only battery I'll have to worry about is the light meter battery. Everything else is all manual. Crank and Click

I'll definitely give it a shot next season (no pun intended). All I have for the FM2n is a 50 prime, but that's just about my favorite focal length anyways (I know...boring boring boring...). I am still debating whether or not to get an external light meter - I hear they're a significant improvement as far as accuracy once you've got your camera dope dialed in right and I doubt I'll be able to replace the mercury battery or whatever the heck my old nikon uses for its built in meter.
As far as film scanners go, what's one that's worth the coin? I'm willing to go relatively high end if it's going to last and be a valuable asset as far as saving my images goes.
All this film talk reminds me that I'll have to start learning how to load/use sheet film as I might be picking up an old rollei MF in about 2 months. I've never used any MF camera before.
