So i picked up an old Praktica ltl3 at a garage sale a couple days ago for $10. it came with a 50mm f1.8 and a flash so its pretty tight. I went to go buy some film for it today and realized that they dont make the type battery to power the light meter. It can still shoot fine its just that i cannot tell if my aperture and shutter speed settings will give me enough light without having to develop the film and see for myself. I have taken a dozen shots already and i am using a d3000 to base my settings on.
I am just wondering if anyone has any knowledge of old film slr's and if i could maybe replace the battery with maybe a different type. It would help instead of carrying around an other cam and doing test shots on that cam.
