Anyone tried this before?

IB4 shitty bokeh due to nature of lens
>> Anonymous
I've got a 500mm mirror lens.

Cons: Absolutely fuzzy, not sharp at all. Suspect it's out of collimation, but can't collimate it. No aperture adjustment, stuck at f/8 all the time. Shitty bokeh, but who really gives a fuck?

Pros: It's a cheap way to get to 500mm and longer. It makes you look like a cool spy.

I've used them, and if you need a really cheap 500mm or so lens, its your only option. However, I hate using these. I hate these due to the nature of the lens and what it does with the light patterns because of the mirror in the front. I can forgive the single aperture as I have made wonderful pictures mounting on telescopes and microscopes, but reflex always seems to make poor light patterns.

I have a 500/f5.6 Rubinar lens. So far I'm content, but I admit it doesn't have a lot of practical uses.

Pros: Cheap ($300), short, very sharp, built like a T-34 tank.

Cons: HEAVY like a T-34 tank, bokeh, fixed aperture, terrible quality of bundled accessories, doesn't fit on Canons due to protruding flash.

Also, don't buy cheap Chinese mirror lenses, they all suck. Russian mirror lenses can suck too, but at least you have a chance.
