I only came across the specifications for this when looking into the possibilities of creating a chipped adaptor ring to allow using Canon lenses, the MPE-65, on some high speed video camera bodies at work for a very specialized application. The amount of communication between the camera and the lens was a bit surprising to me. The breakdown on the data structure used in the packets of information used by Canon and Nikon has been sorted out by other engineering research groups and this is where my information comes from. In this case the client decided that the ability to do strain imaging from the videos of the specimens being tested was not important enough to justify the cost of development. Pity as it seemed like a very interesting project.Originally Posted by iND
