The though of dealing with loads of AAs doesn’t sound fun
I have two F100’s. Never carried around a load of spare AA’s, just the 1 spare set just incase. Batteries last a long time in them. The F100 is a super camera, one of Nikon’s best ever i reckon…
I don’t know about the F100 but the F80 uses 2 CR 123 batteries, they last for ages, even when the camera was left switched on in my camera bag for a week, they still didn’t run out.
