FYI
I just contacted Conurus with the following question:

Hi
We are running the biggest Contax Community forum on the net among other forums and heard about your products. Are you planning to release adapters for connecting either Zeiss N Lenses or Zeiss RTS Lenses on Minolta/Sony DSLRs?
Thanks in advance

Hi Dirk,
Thank you for your inquiry! Please relay this information to your forum.
For N lenses to Minolta/Sony, we see this as technically impossible. The aperture of N lenses is controlled electronically but for Sony it is a mechnical linkage. While it is possible to turn an electronic signal to mechnical movement, there is no way to do the opposite with a fast-enough response. The same applies to other mounts with mechanical aperture linkage, such as Nikon and Pentax. (Pentax is even more impossible because both focusing and aperture are mechanical.)
We have no plans to introduce anything for Y/C mount manual focus lenses. I am not familiar with those lenses but my understanding is that there is 1mm of film-to-flange distance between Y/C and Minolta Alpha mounts. However, the Minolta/Sony mount throat has a small diameter and there is not enough room to fit an adapter in between.

If there is enough demand, we might try to get special prices for Contaxinfo members.
But first I would like to get the view of Dr. Nasse of Carl Zeiss about this. I sent him today an e-mail with a link to the Conurus website and asked him about his opinion. As soon as I get an answer, I will update you on this...
