I suppose we can all blame Minolta for this whole mess. 🙂
Reasons? (1) Minolta was the first to abandon the lens mount it built its previous system on (MC/MD) for its autofocus A mount (which lives on, digitally speaking, via Sony), and (2) together with the Maxxum 7000, was a runaway hit that caught everyone literally off-guard. Whereas everyone else made tepid toe-dips into the AF SLR world with modified versions of existing bodies and one or two AF lenses, Minolta basically bet the farm with a full-on, from-the-ground-up camera and lens system. (The "betting the farm" part, in this case, was far more than poetic: Minolta had long been the "weak sister" among the majors, and rather desperately needed another "hit." This was also the impetus for the earlier X700, which was to Minolta what the original Taurus was to Ford in the 1980s: literally a do-or-die proposition. Had these cameras failed on the market, Minolta might have left the camera scene a lot longer ago than they did.)
Okay...where was I?...Canon and Nikon got snookered badly, and had to speed-up whatever AF camera plans they had cooking in R & D. Nikon managed to do it while preserving their F mount, with a caveat or two; Canon decided to follow Minolta's lead and ditch the FD system (My slightly tongue-in-cheek gripe to a Canon rep at the time: "So this means you're never going to tell me what that "Reserved Pin" on the back of most of my FD lenses was going to be used for?") for their EF mount, named, ironically enough, after one of their more interesting FD-mount cameras (and which I foolishly traded away for an A-1...nope, not gonna talk about it now...)
Which, of course, brings us all to where we are now. But look at this way: if you think Canon's FD-based stuff is depressed in price, try pricing Minolta's MC/MD stuff right now, with the possible exception of, say, a clean, late-model MC 57mm f/1.2, mounted on, say, a clean, working XK Motor. Just don't tell me you have one for sale, okay!?
