Contax/Yashica (C/Y) to Pentax K adaptors

Hi all,

i've a few C/Y fit lenses from my 35mm days which i'd like to try on my K-x. There are several sellers online offering such adaptors now. Has anybody else any personal experience of this and could possibly make a recommendation...or alternatively warn me off if it didn't work out?

many thanks

A few months ago I did this, but sort of the opposite way round - an adapter to allow manual use of my Pentax lenses on a Sony Nex body. I ordered the adapter on eBay, from a seller in China (the country, not the pottery), for about £12 with free P&P. I think it took less than two weeks to arrive. It is all metal, seems well-made, and works perfectly.

Cheers.

I've always wanted one but due to some specific difficulties the usual adaptors were no use, apparently now they've produced an adaptor with a lens (the usual ones are lens-less so don't affect optical quality). I've no idea how much they are or how good, but I've always wanted to use my Sigma 24mm C/Y fit lens. It was very sharp in the bad old days of film.

SRB Griturn are the adapter experts, who make everything that can be made. You could give them a call and see what they can offer, or perhaps their website lists something appropriate.

Thanks for the responses guys. I'll do a bit more digging around to see if I can discover anyone who has actually used one of these specific ones and see what they thought. In the meantime John, i've had a look at SRB's website and sent them an email. They do seem to be quite a useful looking company for future reference.

If anything does come of this and I decide to try one of these adaptors i'll post some of the results on here with my thoughts...it might help someone else. I thought i might as well try and make some use of those lenses as sell them for a pittance.

regards

Haven't seen adapter for pentax, but it is possible to do a lens mount reversion.... take a look at this link:
www.leitax.com
it's quite simple, although the machined lens mount they are selling is quite expensive

I've used two converted Contax lenses : Planar 50/1.7 and Sonnar 85/2.8 and they were absolutely beautiful with my K10D.

I converted a Contax 35mm using the Leitax lens mount converter. The process is fairly simple and the instructions comprehensive. It's a good lens which I still use, and if converted carefully and parts kept after removal I would imagine a retro conversion back to Contax mount should be possible. The only problem is the lack of auto diaphragm.
