I'm a neophyte to the rules of the photography world, and next year I will take my first photography class in school. The class requires a manual film camera. I'm opting for a nikon, just because I love everything about my current d40. My question is- am I able to use lenses I have purchased for my d40 for a film camera? also- for film lovers- what sort of film camera do you recommend, anything goes as long as it's all manual.
