These lenses are difficult to use and don't produce sharp images. I have a Nikor 500mm mirror...I almost never use it. What are they good for other than taking advantage of the unique bokeh?

What about contrast? By eliminating the fundamental waves (first order) you eliminate a major part of the resolution. This can be compensated for but is usually not.

Yep, it's available in Sony E-Mount. And really only good for distant subjects. It can be a little tricky to use though, particularly for beginners.

But beyond that, which camera mounts does it fit?
According to Tokina EF-M, E and X.

Field of view is like 1350mm on a full frame camera.
