Thanks. I wonder how the SEL 50 would match up in this test? But what you've done is incredible and I appreciate the efforts you've undertaken to complete this.

It was a surprise for me when I ran some test on SEL 50/1.8 as it turned out to be very good in both resolution and contrast, despite some corner and CA problems there are probably very few manual lenses that come close. Many manual lenses are very poor wide open. The only lens I found so far that did equally well at f/2 or faster was G.Zuiko 40mm/1.4. Here is my old chart:

100% center crops, all taken at ISO 100, manual focus, tripod
