[UPDATE: This rumor now appears to be false.]
The latest rumors about the upcoming Canon full frame mirrorless camera suggest that it will accept Canon EF lenses on the camera . . . without the need for a mount adapter!
“From this information, it’s a working theory that the RF and EF mount will differ slightly and EF lenses will mount on the RF mount and cause it to “switch” to the EF protocol.”
That’s a big deal. Back in 2015, I said Canon needed to build an A7-like camera with an EF mount:
“I think that most of us who have a bag of Canon glass and are fans of what Sony is doing truly want Canon to make a great mirrorless camera. And I think if Canon simply took a rebadged A7R II or A7S II with a Canon label and EF mount on it, most of us would be jumping for joy saying, “Shut up and take my money.”
Of course, we know that Canon can’t make the exact form factor thanks to the longer flange distance of Canon EF mount as compared to Sony E-mount, which is around 40% of the distance. But there are some smart dudes engineering these things for Canon. They can think of some creative ways to mask that difference in the flange distance for the final body.”
Is this really what Canon is doing? Interestingly enough, it also lines up with rumors from 2017.
If Canon somehow manages to pull this off with the type of integration suggested by these rumors, then the camera giant may end up erasing the past decade of mirrorless product development and leap-frogging the progress Sony has made in building its mirrorless system and gaining market share. And Nikon, poor Nikon, becomes an afterthought again….
Imagine buying a full frame Canon mirrorless camera and your entire collection of EF lenses being native fit and operation. That’s exactly what I had on my wish list back in this 2015 post.
“What we don’t need is another mount for a full frame mirrorless Canon camera to add to EF, EF-S and EF-M mounts. I can live with a little extra bulk too. We just don’t need all the extra bulk and weight for the mirror assembly and pentaprism. There are also over 110 million EF lenses floating around out there. The owner of each one is a potential customer for the Canon EOS A7…. Let’s stretch this amazing system out for a while longer.”
Canon shooters, what do think about such a possibility? Would you buy the camera? Should Canon pay me royalties for telling them how to dominate the market?
