I'm getting ready to sell my last Canon SLR and 50/1.4, as I have a Nikon dSLR and a couple of their AF lenses (20/2.8,50/1.8) and a flash. Much better to have one system's equipment rather than the lonely 35mm body. I had planned on buying an FM3A as I prefer to focus manually, but I've read that it's not ideal for glasses wearers. I could use cheap Nikon diopters, but it's a bit of a pain to switch back and forth, and I'm nearsighted enough right now that composing without glasses is difficult. (Someday I'll be brave enough to go in for a LASIK consultation) Which led me to the F100, actually a little cheaper from KEH used, which would match with my AF lenses and has the high-eyepoint feature for glasses wearers. I'm okay with that, but unsure how functional it is for manual focusing. So I guess the prime questions here are to the FM3a's usability with glasses, and the usability of the F100 with MF lenses. Any help would be appreciated.
