Hi gang!
Is there any adaptor that can allow me to put a sigma 600mm mirror
lens on a Canon camera with an EF mount?

Thanks for any help!

What mount does the Sigma lens have now?

What mount does the Sigma lens have now?
I tried it out and it's an FD mount - any hope for that?

It even appears like the FD mount is part of the lens: could that be
possible?

Thanks Rob!

Hi gang (and Rob too, thanks for your help)

Well I got an FD lens to EF mount adaptor for the sigma 600 lens and
it works fine. The only thing is the lens has no contrast. It can
focus through its whole range fine but the picture is very faint.

Someone told me that the coating inside the mirror of the lens has
oxidised and is no longer reflecting much any more. Are there any
camera places that can recoat the mirror part of the lens? Any places
in Queensland?

If I don't arrange to get the lens recoated, how much would it be
worth on ebay?

Thanks for any tips.

Becomes a problem when you have to recoat the mirror. Dismantling the
lens etc then it will have to be re collimated when its re assembled.
You can get the the lens recoated, thinking someone in Tasmania - not
sure if that's still available- they did clean and polish lens elements.

Personally may not be worth the effort. People who repair lenses will
charge heaps. Check out the web for lens repairers.
