I just purchased a 200mm Kokina lens at an estate sale for $50, purchased a custom made adapter from Precision Parts, and screwed it on my Atik 383 OSC camera. It comes to focus which is great. I also purchased a Pegasus Focuscube v2 and the gears and timimg belts to add autofocusing with Sequence Generator Pro. If anyone has been down this path, I'd love to here from them.. I am especiaslly interested in whether anyone has used a Tokina lens.
