I've seen it in their catalog and thought of getting one for my Bolex (I have a large Canon zoom I want to use on it). I don't know if it's on their website but you can search for it. The item number is 10-0791. Thier website is at:
I have been shooting surfing since the mid sixties. Over the years I have used a Bolex H8, H-16 Rex, Beaulieu Super 8 and a Bolex H8 converted to Super 8.
I have used the Pentax screw to "C" mount adapter with all of these cameras and used lenses such as 50 mm Takumar, 135 mm Takumar, 200 mm Takumar and a 450 mm Soligor with excellent results. The focal length lens you use has more to do with the distance from the action than anything else.
Since you are taking your image from the center of the lens, you may find that even some cheaper 35 mm lenses yield excellant results. Most lens abberations are found on the outside edges of the lens.
Also the RX mount is only applicable on short focal length lenses. Telephotos seem to be unaffected and focus just fine.
