Originally posted by Wheatfield If too many EF users just buy an RF body and an adapter for their EF lenses, Canon will have to look at forcing people to buy RF lenses.
There are three kinds of RF-body customer: those with no RF lenses, those who mix EF and RF, and those with only RF.
· For EF users who just buy an RF body and no RF lenses, does anyone
honestly think that by being forced out they'll buy RF lenses? No. They'll buy a Sony with EF/E adapter for 10% of the expense and 99% of the functionality.
· For people who use older EF lenses but
also buy a couple RF lenses, Canon gains nothing from forcing them out, because they risk pissing them off and they are anyway already buying lenses. In fact, long-term the chances are they'll buy more RF lenses instead of EF lenses.
· The third group would obviously not have an impact.
You don't stimulate lens sales by blocking users from using their gear. You do that by making the new lenses
much better than the prior ones. EF lenses had AF when FD didn't, which was enough of a break to make the gamble worth taking. RF has no such advantage - so Canon can't afford to kill the adapter this time. I'd argue that their lens release strategy has been focused on nudging people to "hey, this cool and expensive RF lens has no EF equivalent". Sure, they are halo products, which makes them irrelevant for most users... but most users don't want to adapt in the first place, either.
Besides, CIPA data shows that the ratio of lens:body sales keeps going up since the RF and Z systems came out, so obviously people
are buying new stuff.
