Thanks for posting. I really do not like camera / lens tests taken out of the context of photography. I mean they are useful up to a point but most people actually use photo gear to make images of more than just charts. I like the way Frank explains things. very cool.Frank Doorhof was one of the beta testers of the Credo 50 and his given it a fairly good workout. He's just published a user review
Warning: there are no MTF charts and no UTT targets involved in the article!
Enjoy!
It is not all about resolution figures. The look and feel of the lens and sensor combination is important to a lot of people.
Regarding the Zeiss Otus lenses. Yes, they are superb lenses and test well but since they lack AF they are not that useful in real world use for people photography since most if not all DSLRs are really ill equipped for manual focusing. The Leica S might be the exception with the awesome split prism screen. Mirorless cameras like Fuji's X-T1 have nice focusing assist features though.
If you are a resolution junkie and want to absolutely obliterate a D810/A7R in resolution then get your hands on a 60 or 80MP phase/leaf back and some rodenstock HR-W lenses and take a few images of a cityscape in decent light. When you open the images in C1 and zoom in you will say holy crap Ive been shooting through a coke bottle all these years.
