I have in my hands this lens. This is the first I've ever seen, quite impressive. It has X Y shift as well as tilt. Beautifully constructed. I am cleaning the optics for a store and once it is completed the store will post it for sale. For those of you very interested the store is Penn Camera in Washington DC.
I wouldn't be able to clean it, what with drooling all over it at the same time.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
