Question Re Canon R/RP Adapter
Dec 22, 2019 14:43:12 #
I currently have two Canon APS-C cameras, and a number of lenses, some of which are APS-C and some are full-frame. Some of the lenses are Canon brand, but others are Tamron and Sigma lenses with Canon mounts. Question: Will the non-Canon lenses work on a Canon R or RP camera with the Canon adapter? I feel that theoretically they should, but also know that Canon might build a chip into the adapter to test for genuine Canon lenses.

Technically, the 3rd party should work. I believe in practice, it's hit n miss. You might consider why / if to retain cropped lenses, any brand, when considering an investment into a full-frame mirrorless body.

Some if not most of the features will work with those lenses. That said, I've read a few remarks about 3rd party lense not being 100% compatible. Things like slow focus or wrong or missing exif info for that lens.

My experience:
I have a Tokina 11-16 EF mount(but designed for Crop sensor) that vignettes severely from 11 to 15 mm, so if I keep it, it will be as a 16mm lens only. Rough Calculation, at 11 mm, the usable portion of the picture is approximately the equivalent of the 16 mm would deliver.
I also have a Sigma 18-250 that also shows vignetting out to about 70-100mm; so I am replacing two of my favorite lenses as I move to the EOS R body with the empty adapter
Canon EF lenses (true EF) work flawlessly, although I have a 70-300 that has difficulty keeping up with the EOS R's focussing speed, and it chatters at times

I have used the Sigma 150-600C and the Tamron 18-400 with my R and adaptor with no problems. No problems with my Canon brand lenses using the R adaptor either.

Several of the non-Canon lenses are EF. In addition, I have a set of Kinko extension tubes and a Tamron teleconverter, which, while not actually lenses, will fit on an EF camera.

They will work if you manually put the camera into crop mode. the R does that automatically for EF-S Canon lenses but not for third party. I think the resulting file is about 12MP or so.
If you do any 4K shooting they're worth keeping for that as the crop is really similar.
