I have been finding that CA problems with the 35 1.4 as well and I did a few more tests with focal and I have come to find that my lens now sits perfectly at -1. The most important test to dun is in real world as well but with FOCAL it sets your out on the right track. All of my photos see to be sharper and more in focus. however that also has to do with my learning curve coming from Canon my whole life.
PS I am in love with this camera! It is helping me get back to the basics of photography and really work on my technical skill.
