1981 saw some major technological milestones: the first manned orbital mission of the Space Shuttle...the debut of IBM's Personal Computer (aka the PC)...the first flight of Boeing's second-gen wide-body, the 767...and the first Delorean DMC-12s began to roll off the line in Ireland. In step with such advancements, Pentax sought to push the technological boundaries of the 35mm SLR, much as they had a decade earlier with their Electro Spotmatic (ES) aperture priority autoexposure model. Only this time it was focus rather than exposure that they were seeking to automate. In late-'81, the ME F would become the first production 35mm auto focus (AF) SLR (with a caveat ;-)) to hit the scene.
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.
