I used to have a working FG but now it is not functioning. Tried to get it fixed but didn't work. Now planning to buy a new Nikon camera, since I already have the 50mm nikon E series lens. So, FG is way cheaper compared to both FE and FE2. Those expensive ones have fast shutter speed up to 1/4000 compared to 1/1000 on FG and also they feature DOF preview, if I am not mistaken. Is this all or I am missing some other benefits of FE and FE2 over FG. Would you pay almost twice as much for FE or FE2 ? If so, why ? All these aside, can I use my E series Nikon lens with both FE and FE2 in aperture priority mode ?
