I bought an FE in 1981 then added two chrome bodies a few years ago. I use K, K2, and K3 screens with these. Last year I got a very cheap Nikon EM from auction-site. Surprisingly f/3.5, f/4.5 lens focusing is easier than FE in this little body although fixed screen in EM should be equivalent to FE Ė K screen. My Nikon Emís speed are not accurent in the slow side but doesnít matter too much for street photography.
The FG is a sleeper that packs a lot features into Nikon's smallest ever film SLR. With 50mm and 100mm E series lenses, it's a great, almost pocket-size, outfit. Preferable to the EM.
