If this is not the usual adapter with only air inside and some wiring on the barrel, there should be patent applications around it, I suppose. I sincerely hope this solution does not contain moving parts or optical elements.

Patented 2-3 years ago, so long ago that people don't remember it.

If the new camera is not a native EF mount then it is a problem for owners of EF lenses. Is it that hard to understand?

what problem? There is absolutely no problem, as long as EF glass can continued to be used on new mirrorless system ... a decent Canon "adapter" is definitely no problem, but a simple, cheap and effective solution to ensuring backwards compatibility for legacy EF glass.

Mounting EF lens to non-EF mount is a problem and the fact you can solve it with a simple adapter is irrelevant.
You can argue semantics all you want but it won't change the fact.

PS - will it really be 'cheap'?

I really struggle to guess what this could be - it certainly seems to imply that it won't be built for only EF lenses, so what's left? A new lens mount with a new adapter? A telescoping lens mount? An lens mount which takes EF and EF(?) where the new lenses have optics which go into the camera past the mount to get the right flange distance? Time for some wild speculation?

Mount adapter with SLT mirror built in...

other "nice solution" would be a lens conversion Service for EF Lenses. Technically it should be no problem to screw a adapter on each lens.

then we all can be happy, we have 4 longer lenses in the bag and a shorter camera, and therefor trade in the OVF :)

Question - would there really be a need for an SLT mount adapter to allow autofocus? I was under the impression that the bulk of Canon's lens offerings could use DPAF and wouldn't require an alternative focus system?

I can see this being...Full frame lens can be cropped to APS-C crop in camera, so you can get longer reach with telephoto if you want.
Wide angle APS-C lenses, can but used even wider than before, but the camera would crop appropriately and automatically to get the most out of every Canon made lens if you want it to.
EF-M mount, and EF adaptor in the box. Full canon ef, ef-s, ef-m lense support, and better use of them (wider is wider, longer is longer).

You don't get longer reach by cropping in camera - you just get a cropped image.

The OP talked about an interesting way to fit EF lenses which suggests a new mount. Are you suggesting a mount that accepts EF-S without an adapter? Or a new mount with adapters for EF-EF-S and EF-M?

Or then this fairly new one: http://www.canonrumors.com/forum/index.php?topic=34242.0 , which is the mirror in the box solution.

Maybe the solution is that Canon will build two different lens barrels for existing optical designs.
Right now, I can use an adapter on the M5 for my collection of FF lenses. That's not a problem for me and wouldn't be an issue for the new body.
I really hope that Canon builds this on the current flange distance for their FF bodies. I don't want some tiny little thin body, I want beef! Just yank the mirror box out of the 5D Mark IV and call it good!!! :o

“a really nice solution for EF lenses on the full frame mirrorless body”

To me, this means NO EF TO EF-M STYLE ADAPTER, because that would not really be anything to talk about, and that's really all that I care about.

It should mean either:

1. A way to mount EF lenses directly onto the mount, or

2. Ability to semi-permanently change the actual mount in a professional, weather-sealed and rugged manner that doesn't involve buttons or switches.

It should NOT mean either an adpater for the body or an adapter for the lens, because none of these would be viewed as a "really nice solution" to a professional.

Leaving throat diameter & flange distance aside, why would Canon consider anything but EF?

The best solution wolul be an adapter like fotodiox fusion nd throttle - but better. With no color cast.
That would be a REALY great use for the empty barrel. A build in ND is absoluetely great for any filmmaker! Options to screw on the lense sucks... slow to put on, bad for the image quality and you need another size for several lenses... brrr


I realy hope its a PROsumer camera, and not another toy that canon appears to like more than the professional sector right now.

Well, we can be assured that there aren't any optical elements, because that would just mess up the.... optics. It could be EF+ of some sort, in the sense that it could be mechanically and optically compatible with EF, but with additional camera-lens communication that isn't compatible with existing cameras.

Maybe, to support T/W controls electronically from the body, for example. The EFS18-135 with the add-on piece lets you control T/W electronically, but it's from the attachment or remote. Just thinking blue sky, it would be cool to set a focus and zoom, zoom out (and optionally defocus), and then have the camera electronically return to that point for video.

Kind of like, with a monopod, when you start focused, move back and defocus, and then reverse the video to make it seem like you're coming into crisp focus.
