Three decades...Six (and-a-half ;-)) models...ONE platform. Approximately 4.5 million bodies sold. That makes the compact enthusiast/semi-professional manual focus line of Nikon SLRs the longest-lived chassis in the history of the marque, and arguably, the most successful. Spurred on somewhat by the success of the Olympus OM bodies but mostly by the groundbreaking Canon AE-1, Nikon's foray into the world of compact SLRs first bore fruit in 1977 with the FM, and ended up with an "old vines" distillation of body and flavor with the FM3A in 2001. But there was a lot of ground covered between those bookends. So which one will be right for you? Let's dig in :-)
Suffers from a quarter-century and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
