Canon R5 - native lenses or adapted EF

[Tulpa]

Hello EOS forum members. I haven't been able to find much online info on how well the adapted EF lenses work on the R5. Does anyone here have any first hand experience?

They work well (AF and IS), except they aren’t corrected for distortion in-camera and are noisy (USM). If you’re looking to use an on-camera mic, go with RF Nano USM lenses.

Thanks!

Can I ask what lenses you are using and how do you like them?

RF 15-35mm is quiet, fast, stabilized unicorn lens. All you really need for narrative film in most cases.

RF 50mm 1.2 is possibly the best image I have ever seen from a lens, better than any cinema lenses I have used. But it’s also the full frame and autofocus that probably play a major factor in that. But it is regular USM so it’s about as noisy as the regular EF lenses. 

If you don’t need on camera sound, and watch distortion, I’d go with the Drop in Variable ND with way cheaper EF lenses. I think the EF 24mm 1.4 is stellar.

I am confused now...

From this 2017 list here?

Or is the accurate one this other one here?

The last list. The only EF (full frame) nano usm is the 70-300. There are a few EF STM lenses but not all are that quiet. The 40mm pancake I have is not.

And not Canon branded?

Thanks again @independent

I'll take a look at the 15-35.

Only 3rd party are not corrected , most Canon EF lens have correction done in camera

..and as I learn the hard way with my Pocket (my favorite Olympus 12-100mm is just..ok...), that is a huge issue with modern lenses.

I have the 18-135, is pretty silent. It is the last version though.

Can one adapt EF-S lenses on an RF camera with the ND adapter? Do they have a crop mode?

Really? Such as?

None of my EF lenses can be corrected in-camera on either the R5 or R. The option is simply grayed out. Also, the R5 manual states that RF lenses are corrected during movie shooting. No comment about EF, but Canon USA confirms the R doesn’t support EF lens correction.:

 

Here is the info from the R5 Manual:
