Hello all. I just took some test shots to compare IQ with a few lenses at 100mm. Wanted to see how the Viltrox EF-R2 affects IQ if at all.
I used a variety of lenses, RF 24-105, EF 24-105 (1st gen), RF 100-400, Tamron EF 70-200 2.8 G2.
The EF 24-105 was noticeably better than the RF 24-105. Should that be the case? At f/4 it was way better at the sides. At f/8 both improved but EF was still a touch better.
2nd question, the EF image shows a touch more of the subject. Is that just the fact that that adapter places the lens a bit further from the sensor?
Thanks

I still use the 7DII and it's still as good as it ever was. It makes a great back-up unit for your R6, especially as it is an ASP-C unit. Frankly, you won't get that much for it now, and I would suggest thinking carefully about what you would get to replace it and at what cost.

I think the issue is that Paul is concerned at the resolution of the RF 24-105, not so much the generation 1 EF unit.

While it seems to have been dropped, if you want to measure the focal length:
