There's a single focus version too, this one https://www.youtube.com/watch?v=Ab7KFtUFv8s
Basically it's the 1.33x-40 compact with SLR Magic Rangefinder builtin, non-removable.
Also, there are two version of each, the one with near/normal focus distance and the other one with feet scale (they call it Cine, if I recall). Optically they're the same, with just different distance marking and the one with feet scale costs more.
