OK. I have had 3 copies of the CV 15 E mount from 2 dealers, one was sent back to dealer A for a refund, one was sent back dealer B for an exchange. Today I received the replacement copy from dealer B. Took some shot at infinity to check the corners. This time the right corners look OK to my untrained eyes, the left corners still look smeared. I don\'t really know how to do 100% crop but you get the drill. What do your guys think?
