But I do, on my R7, and it performs very well. Much as I love the EF-M 32 on my M6II, I wouldn't buy an RF-S version for my R7, because the RF 35 is so good already. What it loses in aperture (2/3 stop), it gains in minimum focus and IS. I can handhold the 35 on my R7 down to 1/2s. With my 32 on my M6II, I don't go lower than 1/125.

the R7 + RF 35 isn't exactly a small setup like the m6II + 32 f1.4

I agree on the ss you discussed

I'm not convinced on the sharp across the frame wide open on that lens without stopping down a bit,

Well, here are a couple of samples I just took wide open. First the whole frame:

And now a 100% crop of the upper left corner:

The focus was on the symbol above 'SIGNET'

And another, full frame first:

And 100% crop from upper left corner:

Focus was on the colon

Looks pretty sharp at F1.8 right at the edge. Certainly good enough for my purposes.

thanks for these, yes, looks fine

and the backdrop blur I want is ff equivalent of 50 fov f2.2 not having to stop down a bit

but as far as sharp across the frame at f1.4 (50 fov f2.2 equivalent), I'll stay with my m32 f1.4 and m6II since I'm not buying a crop R camera, which I think is for reach with long lenses, wildlife and sports

"The R50's most compelling feature is probably its autofocus system. It's a relatively simple-to-use but powerful system that combines a series of subject recognition modes with tenacious tracking."

That's pretty cool for a bottom-of-the-line camera.

I didn't. The tests are the crops. The point was to show how sharp the lens is wide open at the edges (we all know it's sharp in the middle, we don't need yet more photos showing that), when used on an RF mount crop camera. The crops are 100%. The downsized full frames are just to show you where the crops are taken from. No need to clutter things up with bigger images than necessary.

do I have this right?

the EF 16-35 f4 IS L wins at 16 mm f8 - although heavy

the M 11 -22 at 11mm is 17.6 mm (FOV) but comes in second place @ F8

and the RF 16mm f2.8 doesn't have IS and comes in third at F8

Apologies, mea culpa, I did these December 2021 and assumed with the 16mm series starting with f/2.8 they were all from the RF lens. I somehow used f/6.3 with the RF lens instead of f/8. I thought those 16mm shots looked a bit good, but you have to look very carefully to see the differences if you're looking at a real print instead of pixel peeking. The extra field of view from the DxO lack of cropping really does affect corner resolution though, and DPP4 seems to give the same field of view from the two lenses at 16mm, almost to the pixel.

Here's the field of view,

RF 16mm DPP4

RF 16mm/6.3 top left DPP4

RF 16mm/6.3 top left DxO

11mm/8 top left DPP4

EF 16mm/8 top left DPP4

RF 16mm/6.3 top right DPP4

RF 16mm/6.3 top right DxO

11mm/8 top right DPP4

Sorry it's too late to edit the original. For the DxO and DPP4 framing comparison, here's another image.

Here you go. Nothing interesting, I'm afraid. Remember that the focus was on the upper left corner in each image:
