Coming-of-age. If any term could be applied to Nikon's auto focus SLRs from 1986 to 1991, that one has to be at the top of the list. The transition to AF maturity coincided with Nikon's rise to second place in the overall SLR market to essentially form a duopoly with Canon as the other members of the then-Big 5 (Minolta, Olympus, and Pentax) slid further and further behind, and in Olympus' case, dropped AF SLRs completely. The irony in all of this was that Minolta had gotten the drop on everyone and dominated the first few years in AF SLR sales with their groundbreaking 7000 model. Canon brought out their T80 FD-mount SLR a couple of months after the 7000, and it wasn't even close to the Minolta. So much so, that Canon abandoned further FD-mount AF development and began a crash program to come up with a completely new mount and SLR system. It would be two years before they brought out the EOS 650. For Canon, that would turn out to be time well spent, as the EOS cameras rocketed them to AF SLR sales leadership in rather short order. Nikon got on the board in April of 1986 (over a year after the 7000 made its not-so-subtle entrance). While the F-501 did not necessarily surpass the 7000, it was a match for it and gave Nikon a toehold (and critically, a one-year head-start over Canon to get established in the market) until they could bring out their second generation enthusiast AF SLR in 1988. By the mid-'90s Nikon had clawed their way past Minolta and tried to maintain pace with Canon in market share (which didn't happen, but they did comfortably establish themselves in second place :-)). Let the retrospecting begin...
Suffers from a two-decade 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.
