500mm Kimunor

A co-worker gave me this 500mm f8 Kimunor lens today, anyone know anything about it? Did I take his trash or treasure?

Always worth a try. I have the Tamron BB55 - I really like this lens so give yours a run out and see what it can do (I've found it can be hand-held because they are very light - but you will need support if not using a tripod).

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

Cool, thanks for sharing that! Maybe I can go down to the water front and get revenge on that bald eagle I barely caught with my 18-55mm.

I cannot believe you bird with a 18-55! Just remember to shoot with both eyes open... your left eye to track the bird and your right eye for focus... you will never find the bird any other way as you will only have about a 4-5 degree FOV...

I got the bird it was just too far away for the 18-55mm. After cropping it waaaaay down the IQ was low.

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.

It's probably the F6.3. Runs about $150. Quality control varies greatly on them. Colorado CJ obviously got a good one.

Yeah, sorry about that, it is the F6.3. I bought it at overstock.com for $119.00.

I normally shoot in jpg and this was a jpg. The untouched jpg doesn't look THAT good to the eye, but all the information is there, so with a little pp, you can really get some good pictures.

The 500 mm mirror lens can really reach out though. These bighorns were roughly 50-60 yds. from me and I couldn't get the rams full body in any shot (although he was pretty large). I couldn't back up anymore either, since there was a dropoff behind me with a rushing river.

Lovely shot of the mountain goats (ibex?) Great surprise for me too. May be I should check out the mirror lens too.

Not goats. Bighorn Sheep.

I figured I'd make a gif of the original and the post processed version, just to give you an idea of what it looked like without processing.

I was at the very least, expecting the dreaded ' donut ' bokeh. something i really hate on a mirror and which has stopped my ever buying one, so where are they ? Did you PP them out, or is this a rare mirror that doesnt produce donuts ?

No strong points of light = no donut bokeh.
