I have an F100, an FM10 (if you count that as a Nikon) and an FM3. The FM3 is my favourite, and my main camera - I am about 75% film and 25% digital at present, and 75% of the film is with the FM3 (the rest is medium format). I use B&W negative film only, mainly Ilford FP4 but occasionally XP2, because I prefer it - but even if I didn't I can't get slide film processed at an affordable price.
