Originally posted by Colorado CJ You might just be surprised on how it performs. I just bought a cheap Rokinon 500mm F.3 mirror lens and I'm very happy with its sharpness.
Here is a shot I took the other week. Just a little pp to bring up the contrast
Holy crap! Gorgeous!
I would never have thought you could get that kind of quality out of a mirror lens. I'm sure that good light helps, but still, wow. (But it can't be an F3, right? Is that a typo?)
And I understand you did some PP, but you can't even tell, so I guess you sure didn't have to do all that much to it.
I'm very impressed. I don't shoot with the long stuff at all, but this was a real eye-opener for me.
