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? Perhaps I'm wrong.

Thanks Swerky for sharing

I know that vignetting can be corrected in software. What are issues in doing this correction in software? Some people even add some vignettes to their images.

It can add noise and/or lead to loss of detail (no free lunch). It also takes more time and processing cycles.

The processing cost is negligible--it's just one of many corrections that go into RAW processing. The noise problem is real, though.
