I have an excellent copy of the Canon FD 20-35/3.5 that I have been using on my A7 for a while now. It works extremely well, I would prefer to have something that I can also use on my M2 as well. There is nothing I can fault with the 20-35, and I know that most likely whatever wide M lens will probably not have as good of image quality, but I'm willing to sacrifice that to be able to use it on both systems. I'm interested in something in the 21 range, either a Voigtlander 21/4 or possibly Kobalux/Avenon 21/2.8. I'd be more than happy to send pictures to anyone that is interested. Thanks and have a great day!
