I agree - it's an easy transition from a Canon 7D to ANY of the previous Canon EOS film SLR's. I have an EOS 500n, 50e & 1v, and really, they are all just supporting bodies of varying build quality for the lenses. When I bought the 500n 'new' in the 90's - I thought it was the best thing since sliced bread and ran 100's of rolls through it - you can get these on ebay for loose change now! If you only have EF-s lenses, then get a 50mm f/1.8 - it'll fit both your 7D and any EOS film camera, is only $150 new, wide aperture and SHARP.
