It's all out there -
http://www.zoerk.com/pages/p_mima.htm
medium format lenses on 35mm cameras - with or without shift - they assume
that an 80mm 66 or 645 lens on a 35mm camera will not be the same focal
length - like a 35mm lens on an APS camera, I presume.
I don't think they have OM adaptors, but. Don't know who their N.America
agent is - there is no agent here in Oz and they offered to sell direct.
