Canon R5 + Canon adapter + Sigma EX 105mm 1:2.8 macro

Is there anyone that could use the Sigma with R5:

Is the autofocus and everything else working on the lens?

Can’t speak to Sigma 105mm macro, but my Sigma 150mm macro works perfectly so I guess the 105 will do too!

Mine is just "EX", no "DG" or HSM, it's pretty old. I just tried and it seems the autofocus doesn't work (makes really strange sound and doesn't focus at all, like continuous working of the motor inside). While in manual focus it is OK, and the aperture is working.
But I was curious if there is any way trough settings in the camera to resolve this autofocus problem, or is it incompatibility (I've the lens since 2000, so they are pretty outdated)

I am no expert on this but, there is a longish list of lenses compatible with the R5. I suspect (although I haven’t checked) your lens is not compatible. As far as I am aware there is no workaround in the camera.

I have this lens…

Sigma 105mm f/2.8 EX DG OS HSM

works flawlessly with R5 and Canon adapter.

Just a note; I bought this lens in July 2017 and had to return it to Sigma Uk (twice) who updated firmware initially for 7dii which was underexposing (a known issue) and then a second time when I purchased 6dii. Have had no issues with R5.

Unfortunately the OP has a much earlier version of this lens which, I think, is not compatible with the R5.

Thanks - in which case my reply isn’t any help
