Iīm offering my Carl Zeiss Makro-Sonnar 2.8/100 (n-mount) lens that was converted by Conurus in Canada for use on the Canon EOS System..!
The lens has no marks, scratches, dents, etc. and works absolutely flawless.
The aperture is adjusted via the camera controls, it hast autofocus and comes with the original box, the GB-73 lens shade and the original n-mount parts as returned by Conurus.
The lens is autofocus and the aperture is set via the camera, like with any native canon lens.
I put it up on german eBay. If you are interested or have any further questions, just drop me a message.
