Bob Shell CY adapter to Canon EOSD

I am about to order the Zoerk y/c to eos adapter. I do not know how it compares to the Shell version, but it is supposed to work well, retaining metering functions in AV mode, albeit at shooting aperture as there are is no mechanical or electronic coupling between the lens and body when using the adapter. We will see. In any case I have decided to go to Canon for auto focus, with a view to a digital future as well. I have thought a great deal about the AX and would love to have one - but it is clearly not state-of-the-art re AF, it is big and heavy, relatively expensive, and does not solve my other issue - long lenses. So I will end up with an RTSII with 35,50,85,135 - all of which theoretically will work on the EOS as well, with the adapter - and an Elan 7 with, over time, 70-200, 300 and 400 (eventually). If it goes well I will likely invest in a higher-end Eos body, though I doubt its necessary as the Elan 7 seems relatively robust, reasonably easy to focus manually, has mirror-lock, dedicated DOF preview, TTL flash etc. as well as a fast enough motor (all for under US 300). When full-frame digital becomes affordable in the Canon line up I will be ready for it, and will not have over invested in Y/C lenses (as much as I love the ones I use, there is distinctly less enthusiasm for the 80-200 zoom, and FFL over 135 as compared to Canon L offerings in that range - excluding the ultra-luxury fast long teles which are completely out of the financial ball park). I think this set up will be like eating my cake and having it too. Comments? Sorry if all this is not strictly germane to the thread. David
I did finally contact Bob Shell and he informed me that the adapter would in fact work; the lenses would work essentially as AE lenses did on an aperture priority camera. I surmise that everything would have to be done with the lens stopped down to shooting aperture. That might make for some pretty dark viewfinder scenes (or LED views, I guess), unless I compose wide open, stop down, then shoot.
So David's note is my understanding as well.
Next question is, what would the conversion factor be for the focal length- would you know? Would it be the same 1.6 times that it is for the Canon EL lenses? I am guessing so....

Stephen: as there is no link between body and lens you must stop down to meter at the working aperture. I am looking at the Zoerk adapter - currently waiting on more info re compatability with various EOS bodies. I know for instance, that the Elan 7E meter will not function properly with non-EOS lenses. (See
) Will post more when I have further info.

I have just bought the Canon 10D and I also asked Bob Shell about his adaptor. I think it is very useful in my cases, as I own half a dozen C/Y Zeiss lens. I will be sad to sell my C/Y lenses in order to raise funds for the Canon L
lens counterparts. This is the only way of going digital with C/Y lenses. The 1.6x crop factor is very appealing for telephoto photography. Athough I also have the Contax N-lenses, N full frame digital is too expensive.
My only reservations with the adaptor are it is slow to use; with fast lens you can focus with aperture stop down but with slow zoom lens you need to open the aperture to focus (otherwise it is too dim)and stop down for exposure, and repeat this for the next shots. Also it is slow to change lenses.

Perhaps someone could say to me if these rings must be locked to the lens with a screw or something else or if you can switch off from a lens to another. I mean, can I buy only one of these adaptors for all my contax lenses?
David
It would be great if you can share with us your thoughts about the Zoerk adaptor.
I have both Bob Shell's and Stephen Gandy's (Camera Quest) adaptors. They both work quite well but they both have a little "slack" or movement after you've attached the lens onto the adaptor.
I have 3 adaptors but need one more. Anyone has one to sell? Please send me a PM if you do.

>Having never used an adapter i am curious as to the camera settings when fitted. I am interested in using my CZ lenses on a EOS3 and possibly a future Canon digital. What is the procedure in taking a picture using an ada pter on a modern AF body and which is the best,cheapest adapter.

What you have to do is to manually focus, and of course it would be easiest to do this with the lens wide open, and then stop down the aperture to the shooting aperture.
Your Canon should tell you what the correct exposure reading should be, so you can adjust the shutter speed or aperture to get to the recommended exposure or otherwise. It's a bit like using the old all-manual cameras where you would match the needle to get the proper exposure.
It would be a lot easier to focus if you have a split-image focussing screen on your EOS 3, but if you use a 300D or 10D, getting accurate focus is not so easy, as you have to focuss just by looking to see if the image is sharp on the ground glass. If you need critical focus, you may have a problem ... unless you have very good eyes.

I wonder if anyone has bought the adaptor from Bob Shell. I paid him 3 weeks ago by Paypal and up to now he hasn't told me when he will ship the adaptor. I sent him an e-mail but got no answer. He didn't bother to acknowledge the recipt of my payment. I am starting to get worried now.....$160 is steep for a piece of metal ring

I bought 2 adaptors from Bob Shell about a month ago. It took him a little more than 2 weeks before I got it, but it all depends on his work schedule. I am however, surprised that he has not replied to your emails, as I didn't have that problem. He must be very busy. Either that or it's already shipped and you will get the adaptor any day now.
Like Mark said, there is really nothing to worry about, as Bob Shell is a well respected member of the photographic publishing community.

F. D. Stein (Herrstein), the Bob Shell adapter is not very stable particularly with big Contax Carl Zeiss lens. The design is beautiful but the application fail and could lead the expensive big lens fall out of your camera. Furthermore, make sure that you will get the right adapter that will be stable and allow infinity focus to take advantage of these great sharp Zeiss lens.
