Originally posted by Wheatfield Actually, all it will take is dropping the EF mount and coding the firmware in the new mount cameras to not accept EF lenses.
Eh, one could argue that they could have killed support for third party lenses any day of the last 30 years, too. After all, they have been locking counterfeit batteries for a while now.
Originally posted by Wheatfield Olympus didn't kill the OM mount, they killed the camera side of their business entirely, not quite the same thing, and was done due to the brand simply not selling enough product.
Yes, but when they returned to the business, they introduced a completely different mount and sensor size, which in turn proceeded to be phased out in less than a decade to go mirrorless (which is another can of worms; they killed their DSLRs completely. At least Canon is still producing all the EF bodies and has released several lately). It's also kinda similar to what Sony did with the Minolta A mount... the moment they got a decent lineup for the E mount the A-mount was done and dead. At least they made a monster camera as a swan song for their users.
Originally posted by Wheatfield My understanding is that the SR mount lenses would work on MD mount cameras with a few exceptions, so while they dropped the mount, they didn't abandon those users. Minolta maintained the MD mount until they were bought by Konica, who killed it, Nikon has maintained compatibility with their full spectrum of lenses, albeit as a feature on the higher end cameras.
No, the SR mount (manual focus only) has 1 mm shorter flange distance than the A mount (AF lenses), so no infinity focus. They actually pulled the "screw manual focus lens users" about two years (February 1985) before Canon did (March 1987). From
Wikipedia:

Originally posted by Wheatfield So far, Pentax has just about the best track record in the business in this regard, but even they tried to drop compatibility with non A series lenses, hence the green button metering kludge that was introduced in the first firmware update on the *istD due to the well deserved slathering from the customer base.
Completely agreed! I wish they'd bring back the coupler, but I don't think they ever will... they might think we will all be using K and M lenses
Originally posted by Wheatfield What Canon did was to tell their customers that they would be supported into the future, and then put the T90 (more or less an EOS 650 with an FD mount) out there as evidence of intent and within a couple of years dropped support entirely for FD cameras. A friend of mine had a T90 which stopped tripping the flash a couple of years after he had bought it, and about a year after the warranty expired. All that was wrong with it was the camera would no longer fire the flash, everything else worked. He sent it to Canon Canada for repair, they sent him back a disassembled camera with a note that it wasn't repairable and would he like a deal on an EOS.
He bought a Nikon and sold all of his Canon lenses.
Canon did it once, I don't think they will have any qualms about doing it again. It depends on if they decide they want to sell new lenses for their new mirrorless cameras or not.
I bet they want to sell lenses.
Then the problem was not that they made the EF mount, but how they handled it, which is a completely different story. Don't get me wrong, I absolutely agree that dropping the FD like a hot potato for the EF system
was an anti-consumer move. I just don't think that they will do the same
now, or that others will be "above it", for the simple reason it makes no sense in the current situation. In the future, we will see I guess... no one would be mad if a company (coughs in Samsung) pulled out completely because of monetary reasons, or if they "just" dropped a format (as per 110 system, 67 system, OM system), even if the practical effect on users is
exactly the same.
