Right, I know you guys won't be able to sleep until I annoy you with some more updates, so this is what I have found.

EOS R focus accuracy with the RF 24-105 and adapted lenses generally seems very good.

My Hoya UV filter makes no obvious difference to focus accuracy or IQ.

At 35mm / f8 with my adapted EF 16-35/4, DoF is effectively the same whether I focus at 13m(40ft), 50m (160ft), or infinity. There are tiny differences if you examine very closely, but essentially you get the same DoF whether you focus at 13m or infinity.

Not the case with the RF 24-105 where it develops weird blurring anomalies at anything less than infinity focus (which is still a little soft, but acceptable). Edge sharpness is better at f4 than f8.

100% crops. f4 left, f8 right. Everything else the same.

Thanks for your help guys. I'll run it by Canon, and see what transpires.
