What you need to do, then, to pick a focal length based on your experience but for the APS-C format is simply divide the focal length you'd have used on a 35mm film camera by 1.6 and use that on the APS-C format camera. There will be a little difference in depth of field for a given f-stop but the field of view will be what you expect.
This is exactly what I had to do in the early days switching from using my AE-1 to the digital EOS cameras. To the OP, I know its a little strange at first but it'll make complete sense once you go over the FOVCF in your head a couple of times as if you were praticing for a speech, I promise! I know it did for me!
