In response to BillB:

>>>>>If you want FF mirrorless lenses that protrudes deeper than the EF-S standard, maybe an EF compatible mount that prevents mounting on both EF and EF-S DSLR's would be useful.

In principle, it is simple to do a small cut out in the mount on an FF mirrorless and a matching key on a deeply protruding lens.  However, I believe that this was not done by Canon for EF-S lenses, so why should it be done now for the new lenses.  Moreover, one may wish to use the new lens on a DSLR with mirror lifted up and using Live View.  This will work, so why to prevent it?

I think that Canon has the right to expect some minimum intelligence from their customers.  I know it is a dangerous assumption (:-)).

In response to BillB:

In addition, such a cut out and key solution will prevent use of the new lenses with anything that currently may go at the back of an EF lens - macro rings, adapters to the Canon M series, adapters for other mirrorless cameras such as Sony A7/A9, various microscope and telescope adapters, third party extenders, etc.

For all of these devices new versions would need to be issued or a lot of DYI work with a file or hacksaw will have to happen.

Canon has no business in making their lenses harder to use whichever way people want to use them.

Hi Chris.
First of all, every Canon camera of mine releases mirror lockup or live view as you start to remove the lens making it extremely risky to try deep lenses on FF bodies, and then there is the fact that lots of people don’t read manuals, so have no idea why the EF-S lenses don’t fit the FF bodies only that they tried and it won’t go!

Cheers, Graham.

Left this thread a while back to conserve time but ran across this article which made me smile.  Back to the future it is, I guess - Reflex cameras.

I found it interesting when he comments, "I don't like ..."

Anyone using these here?

agreed!

Now a FF mirrorless..... that's a different story!

I guess you guys are right, there's no reason I can think of NOT to use an auto-detect EFS mount on a full frame camera.  I cannot think of any downside. if you had a 50-ish megapixel FF camera that become a 30-ish megapixel APSC, that would be neat.

On the other hand, I also can't really think of any EFS lenses I'd want to mount onto a full frame camera, except maybe 17-135 (which would crop 1.6x that), as it is a very nice lens for video, with its very quiet and fast AF motor, that also allows for electronic W/T control.

Anyone Using Vintage Leica M Lenses want to use them FF?
« Reply #321 on: February 08, 2018, 09:56:47 PM »
I am almost all Canon EOS -- the rest Leica glass.  I'm testing a Canon M5 next week with my EF glass but am curious as to trying Leica M vintage lenses on the M5 -- don't have time to order an adapter...

Do you shoot your Canon mirrorless with Leica M glass?

Seems like a natural idea if you like the richness of 50 year old glass....

I'll buy the FF Canon mirrorless even if it is EF/EF-s only but if it is Canon M mount, I could change adapters from Canon EF to Leica M as required!

Just curious!

I think that keeping the EF mount and especially using the Canon EOS lenses with the mirrorless Canon is not possible.The lens-to-sensor distance of a mirrorless camera is less than the lens-to-sensor distance of DSLRs. So for the future Nikon or Canon, the use of an "old" lens will need an adapter.

Certainly it's possible.  The 44mm flange focal distance could be maintained on a mirrorless body either with a deeper body or a 'snout' for the lens mount (e.g., Sigma Quattro).

I'm thinking of this from a "how do we sell more" viewpoint.... If you are a crop shooter and you decide to go FF, it can cost a lot to get all those new lenses, where this way you could get a new body and gradually upgrade..... It might tempt more people to make the jump to FF.

Definitely!  The ability to use EFS on the full frame would encourage a lot of people to experiment or make the jump, I think.  Anything to smooth out the transition curve.

The Sony implementation is really nice; it's transparent, and you just end up with a lovely 18 megapixel APSC camera.  If they did that on Canon, I'd definitely be happy.

The flange back distance from lens to sensor can be whatever the manufacturer wants.  Current mirrorless designs take advantage of the lack of need to provide clearance for a moving mirror and make the camera smaller.  This is popular in some markets, not so popular in others.  The point is that being mirrorless does not mean a lens must be closer, that causes lots of design issues, particularly at the edges of the sensor due to the angle that light rays strike.
