Hi Everyone, I know that wide angle M lenses cause edge smearing on a lot of X cameras. However, as I was browsing flickr, I found this photographer (https://www.flickr.com/photos/copen880/page6), who uses 25mm Biogon and 21mm Biogon with X-Pro 2. Most of the images don't show smearing. Is it because the X-Tran III sensor works better with M lenses? So, I want to ask if anyone here has used wide angle M lenses on X-Pro 2. If so, any smearing? Thanks!
