I picked up this lens off of ebay the other week. I have an EdMika adapter coming for it soon, but so far I've been using it on my Sony A7II, and I've been having a blast with it! It's roughly a 40 year old lens, and has lots of purple & green fringing issues. But it's manageable and the the point of view is like nothing I've seen before.
