Been reading a lot about how nice this lens is so got decided to give it a try. I was able to get one with a stuck aperture but nice glass (radioactive version) for not too much money. Decided to operate on the lens myself and was very happy to fix the issue myself. Even documented the fix just in case. Anyway, took a few shots to try out on my A7r. I am sure with the right setting, this lens can really shine.
