    I'm a little late in doing this, but for anyone still interested in the DIY single-focus anamorphic approach, here's an updated video.
     
    Here are the ingredients:
    Blackmagic Pocket -> Metabones Speedbooster -> Jupiter 9 85mm -> Isco Ultra Star -> Polaroid 250D Achromatic Diopter (77mm) -> focusing tube -> Cavision .6x Wide-Angle Adapter (82mm)

    Main difference from my first setup is the use of an achromatic diopter (the Polaroid close-up filters aren't too bad, btw!) and I've snugged the focusing tube up a bit so it doesn't jitter as much.
    Now I'm trying to figure out a variable neutral density filter solution.  The end of this thing has > 82mm threads, so that's a pretty huge ND filter... but at the same time I don't know that I like the idea of an electronic ND filter at the mount.  Might have to figure out something in the middle of the pipeline.

    Awesome!
    Tried with tele adapter on a Sankor 16D and it works too.
    Thank you so much for this thread!
     
    I think just need a wide or tele converter with 2 components,the wide and the diopter,dissasemble and use the wide one to get in focus.
    I would like to do this with my Lomo square front too. So,the issue is get a huge lenses with the same power (in opposite?) -10 and +10 for example,right?

    Hey guys!
    I stumbled upon this thread while researching tricks and workarounds for single-focusing anamorphic lenses.  Initial searches brought me to the "Fokus|Automat" project: Technically very impressive, but bulky and seemingly complicated... and it appears to no longer be in development.  Later I found this thread and was inspired to have a try at focusing with a wide-angle adapter.
    I received my 0.6x Wide Angle Adapter yesterday and came up with this short test.
    Setup: Blackmagic Pocket + Metabones Speedbooster + Jupiter 85mm f/2 + ISCO UltraStar 1.75x + 77mm Hoya +4 macro filter + 82mm Cavision 0.6x wide angle adapter
    (More details in video description.)

    Stretched from 1920x1080 to 3360x1080 in After Effects, then exported at 1920x618.
     
     

    Currently I'm looking for a large (77mm / 82mm) achromatic diopter, which I hope will minimize chromatic aberration and sharpen things up a bit.
    Thanks for sharing your experiments here!

    I've received some messages about the setup and thought it might be helpful to post this.

     

     
    This is the new non-cardboard housing.  
    I'm waiting for my 77mm achromatic diopter to arrive, and will post a new test once I get that.  (Hopefully this particular achromat is good quality... it's both well-reviewed and fairly cheap.  Will talk more about that once I get it.)
