When you install the Canon Mount Adapter EF-EOS ...

When you install the Canon Mount Adapter EF-EOS R, does it affect the shutter sound? The shutter without the adapter and lens sound clear but when I install the adapter with the lense the sutter sound goes down, you still hear it but not as load without the adapter and thd lens. Is this normal? Thank you
Asked by: True
I never noticed but I would think that it may muffle the sound a bit. Just as long as it works properly I wouldn't think it matters. Peace!

I have a Canon 6d and I need a ring adapter to be able to use my Canon EF-S 18-55 mm and Canon EF-S 24 mm on that camera. Which ring adapter do I need?
Asked by: Susana
The Ef-EOS R adapter allows you to connect Ef and ef-s lenses to the new EOS r mirrorless cameras. The ef-s lens where made for the canon ef crop sensor dslrs. Ef-s lenses are not compatible with full frame ef dslrs. The 6d is a full frame ef mount dslr

Does the adapter work with Canon's tilt-shift lenses?
Asked by: TONY
Yes, no problem, I use it with the TS-17. Does NOT limit the tilt / shift movements (why would it when it's mounted behind the lens????) Bonus: if you get the drop-in filter adapter now you can use filters!

The EF Sigma 35mm 1.4 Art is loose when attached ...

The EF Sigma 35mm 1.4 Art is loose when attached to this adapter. There is some play when handling the lens while it is attached. Is this an isolated issue or is this an issue with all EF lenses when attached to this adapter?
Asked by: Tarik
The adapter was designed to mount the Canon EF lenses on it with a close tolerance so there would me no movement between the lens and the adapter. Each manufacturer will have a "different" tolerance than what the Canon tolerance will be and that could be the problem. You might try your other "third party EF mounts" and see if they have the same "looseness" as your Sigma 35mm f1.4 Art lens. If they are tight then it is the lens and not the EF-EOS R adapter.
