I was given an Ensinor 500mm f/8 mirror lens, I bought a M42 to EOS adaptor so I could use it with my Canon EOS camera.
I was struggling to focus, not sure if its because it isn't the sharpest lens, or if I was just bad at focusing. I'm assuming it is just because it isn't the sharpest lens though.
It's amazing how close I get to things with this lens, with my normal lenses I would have just walked away from the opurtunity of filming these dragonflies.

Mirror lenses are pretty optically bad. I would blame the lens ;)

I've never seen a mirror lens used professionally, in my entire life. Ever. Nor heard of one being used. That is like cheap telescope technology inside of a lens. :P
