Sorry to bother you with this, as I'm a newbie here, but would you consider doing a conversion of a Contax V-Sonnar 35-70mm f/3.4 N-mount to a Pentax KAF2 mount (for Pentax K10D)?

I've looked around, and as yet haven't found an adapter listed to cover this possibility.

Is this even possible for mechanical reasons (interferance w/ mirror, etc)?

thanks for the time.

Jeff

There is no adapter available for this combination. I have not tried this myself but some people just loosely mount Y/C mount lenses directly on a Pentax. It won't click and lock onto the camera so there is the danger of the lens falling off. Then a skilled repairman can always do a real mount swap.

Hi Jeff

are you sure that is a n mount lens. i think it may be a manual focus lens for contax. It is not listed in the FAQ section as one of the n lens.

Hi Mark-

Actually, no, i'm not. Was curious, because it actually gave no other info regarding mount. Was shown on Amazon (Zeiss V-Sonnar 35-70mm f/3.4 ) under Contax items....for sl. less than $400 in mint w/ case....since overtaken by events...it's now no longer available...jeez...just saw it a few minutes back....


Was looking for a Zeiss zoom to mount on my K10D.

Thanks for responding, and thanks for the welcome as well (conurus).

Any other suggestions most welcome on this topic.

Thanks again.

Jeff

Hi Jeff

here is a link to contax uk. they list all of the manual focus lenses as well as the n mount lens.

http://www.contaxcameras.co.uk/slr/slrmanlenses.asp

from what i have read here and there the Carl Zeiss Vario-Sonnar T* 35-70mm f3.4 is a very good zoom.

Unfortunately I dont know of any lenses being adapted for the pentax.

good luck
Mark

the 35-70/3.4 is absolutely NOT a N-mount lens!

The 35~70/3.4 has what is referred to as the CY mount, meaning the Contax/Yashica mount. That mount was developed in 1975 for the Contax RTS series manual focus body.

Well, it sound like I'll either have to try "conurus"'s idea about loosely mounting it on the K10D or try to find a "skilled reapairman" to do a mount swap.

Thanks for the info.

Here are some links I have collected from various forums. The only one I have personal experience with is SK Grimes. They are very good.
