    Alignment is easy.  First adjust only rear lens, you still can find a horizontal flare, but very short.  Magnifying LCD to see it clear and adjust to the best.  Then after mounting front lens, adjust front lens only. 
    The key here is the rear lens is not from the front lens, which you noticed it.  So I need to destroy two anamorphic lenses.
    Each manufacturer design the front lens and rear lens has different diopter factor approach.  So we can try different combination to get wider or shorter at focus point.
    And also need to find the way to mount the front lens become non movable.  If set up ok, that is real single focus.  And no extra glass, the image quality is identical as dual focus setup.

    Please refer to this thread, they are the same lenses as this auto focus mods: 
     
    Yes, I need to cut cinelux several times, shorter and shorter to make it better.
    The previous manual single focus mainly drawback is no aperture control, so I gave up.  But the ISCO's  mechanism is really good, it is an internal focus type.

    Very cool stuff, so you merged together a Canon EF 40mm STM and a Cinelux ES 2x and now you have a working FF autofocus setup?
    How did you manage to align all of the elements so precisely, I'm guessing this is more involved than a it seems. Did you need any specialist gear or was it all done by hand?
    Are you going to post instructions or a tear down so that others can try it out too?

    No mater what, you have to adjust both lenses. What I do (or did before I got the Rectilux) is estimate the distance to the object, set both lenses to that distance, then tweak them both until it's sharp.
