DLA of F5.2 on 32.5 MPXL sensor

DLA - Diffraction Limited Aperture

DLA of F5.2 on 32.5 MPXL sensor

whereas, the

RP has DLA of F9.3

R6 has DLA of F10.6

R5 has DLA of F7.1

Canon has FF RF lenses:

RF 800 F11

RF 600 F11

RF 100-500 F7.1

RF 100 - 400 F8

So it looks like the R7 with 32.5 MPXL sensor could experience some significant diffraction problems with these FF RF lenses

if this new R7 is being marketed for birders, where are the affordable RF-s lenses that will not experience as much diffraction issues and will work well with it?

I realize that DlA doesn't kick immediately in at F5.2 -- but these dark lenses will not be pretty imo on the new R7

so then birders who need reach will be back to third party or EF lenses

I would have been happy with a 70-350 F5.6 for an m5II with IBIS
