Originally posted by TomB_tx On the other hand, Canon's change came up with a much more functional AF mount, and their market share suffered only briefly, then climbed. Some analysts credit their strong dSLR position to the decision to start fresh on the mount. I still like the old FL/FD Canon film cameras, and the lenses are cheap on the used market because they don't fit their new digital cameras! So the change was bad for folks selling used, good for those buying...
Perhaps, but I know someone (BIL actually) who after being screwed twice, switched to Nikon and Leica. Clearly his issue was lack of stability in the mount and lack of care for the end used.
Pros can change gear frequently, because they weaar it out, amatures can't. Canon got through the rough time because the photo business was part of a bigger corporation, pentax was not, and couldn't. I am not sure even now, that it could change, and survive. Also, their mount changes had nothing to do with improved AF, it all had to do with making cameras cheap. No aperture linkave specifically. and no AF motor in the camera.
It puts the cost up on everything but a starter kit.
