There is a substantial price difference between these two cameras - I just bought a used (mint) F3T mailorder and 2 AIS lenses locally - For the price of the F3, I could have bought an FM3a and saved $400*US) Also I just realized that the module of my Sunpak 555 provides TTL only with an FM3a. As an amateur on a limited budget, I worry about the LCD's, etc. The only advantage of the F3 is the bright viewfinder- flash use seems easier with the FM3a. Any suggestions?
