Found a great deal on this Zeiss 2.8 zoom. I'll be using it on a M43 mount though (GH2, BMC, etc). There are adapters but I am not sure they will work. I thought this lens had a manual aperture, but it appears that is not the case? Cannot find in any information on the internet regarding the aperture system on this particular lens. The lens I looked at did not close down when operating the aperture while the lens was off the camera. Unlike their Nikon adapter it does not look like the Novoflex adapter will allow for manual aperture operation of the Contax lenses.

Any help/advice would be greatly appreciated.

Yo yo,

This is an N mount auto focus lens. Its a real shame they never made it for the Cy manual 35mm. For more information and the data sheet visit http://www.contaxcameras.co.uk/slr/nlenses/variosonnar1735.html
