Hello, I'm new to this forum and also to anamorphic shooting, though I worked as steadicam operator on projects with rented hawk lenses before. I downloaded the anamorphic shooters guide, read the forum and watched videos so far. Recently I purchased my first anamophic lenses on ebay: http://www.ebay.com/itm/290889768316 a set of Rathenower Rectimascopes 48/2x which I might get soon. Videos on youtube confinced me about how sharp they are. One mount option is exactly like Edwin Lee and tferradans did with their Hypergonars: http://www.eoshd.com/comments/gallery/album/29-hypergonar-hi-fi-2/ http://www.flickr.com/photos/edwinylee/sets/72157625790618742/ However, the Rectimascopes are dual focus and I'll soon have the ability to test how this handles in real shooting. But after reading what JohnBarlow did with his Moeller rig and the option to use autofocus lenses with single AF by half pressing the camera shutter http://www.eoshd.com/comments/topic/2398-my-compact-moeller-322x-rig-scope-on-a-rope I wonder if it is not possible to use a camera with continous autofocus for the rear lens at all. This way one would only have to focus the anamorphic lens and the rear is adjusted by the camera with contrast autofocus. No reason to fear the autofocus might adjust to the backround in this setup, though. I have a Canon 60D and no autofocus lens at the moment since I use my old Contax/Yashica lenses for video and also photos but what I've read in the manual their autofocus won't allow for continous and fluent focus revision. But a Panasonic GH series camera might do the trick and that would be a good reason to buy one. Eventually there is somebody who already tested this approach with dual focus lenses? Thanks, Andreas
