[Sean Simms] “I need to find one that is specially for the ex1 or if there is some
technical number that will tell me if it will fit the camera.”
iirc the Schneider/Century Optics website will specify which camera a given adapter will fit.
An added concern: the simplicity of switching to and from using the adapter. I too am interested in a wide angle adapter for the EX1R. There are some adapters which require macro mode and switching the focus mode, and (I believe anyway) some which do not. If anyone has already compiled this data, I’d like to know which is the most trouble-free wide angle adapter. In the midst of a hectic documentary production day, I would think that it would be good to eliminate as many steps, and variables, as possible. Why would I want to use an adapter which required any more steps than necessary? (I realize that these steps probably become automatic, but still, given a choice between simple and complex, I vote for simple.)
