Oops, brain fart on that!!! The F2's batteries go into the baseplate of the camera, two A-76 1.5 volt batteries....I've got an F floating around here with a DP-11 (i.e. F2-A finder) finder on it, but it doesn't meter! it was last used back when, lemme see, I think it was when President Bush the First was in office...I got that body for $59, without a prism or viewfinder screen, and later picked up the DP-11 at a good price and plopped it on there after removing the Nikon plate on the old F. The F-body that you have had some neat stuff made for it, like Nikon film cartridges, which were felt-less, permanently reusable "cartridges". There are also lots of fun viewfinder screen available. The old, plain, meterless "F" prism is also kinda' fun to shoot with. I hope you have a lot of fun with that camera. I always found that the original F was a good shooter for me...I could see through the viewfinder pretty well, and the shutter release seemed pretty smooth, so I could shoot mine down to the slow speed range without much problem. One odd trick: if you turn the mirror lock-up switch to Lock-up, the mirror will not go up until you press the shutter release button--but you don;t have to press it all the way...you can lightly 'tap" the shutter release button, and the mirror will swing up, but not release the shutter....kind of an off-list, oddball quirk. Oh, and always keep in mind--the F is a deadly weapon if you are attacked!!! Any one of its multiple sharp edged-corners will break bone when the camera is swung on its strap!!!
