[Konvas] OCT-19 mount adapter on a Canon EOS 5D

[Light Collision]

Yeah, at least it works with the 7D and boy, does it work. We shot the last 3 days with the 7D and the Lomos and it worked flawlessly. It's great to be able to focus by tape again, since the 7D has a witness mark. Before the 7D I was shooting digital with a 35mm adapter and my Lomos, but tape focus just wasn't reliable.
Another thing is that even the standard speeds Lomos are like having a fast lens when used with the 7D because you can shoot ISO 640 or even 800 and still get clean images.

The GH1 should be no problem since it has such a short focal flange distance. Even PL is possible since it doesn't have a mirror. The problem I found with the GH1 is the codec and image quality after grade.

Well, at least the 7D works with the OCT19 lenses (has anyone tried the GH1 yet?).

BTW: Not that it helps for OCT19 lenses, but I've heard that Canon will be releasing new firmware for the 5D to allow 24fps.
