The digital picture have finished the review of the RF 50mm 1.8. Wasn't the larger mount diameter supposed to bring, among other things, less vignette to the image?

The RF mount diameter isn’t larger than the EF one.

The RF flange distance is shorter, though, which I understand means light hitting the sensor at more oblique angles which I believe could contribute to the greater vignetting, though I stand to be corrected on that by someone who understands this stuff better than I do.

Perhaps I'm wrong.

It is amazing how a lens hood can give an air of professionalism to whatever kit I may have.
