@Bold, tito, nickgorey, nahua, richg101, quickhitrecord and everyone else in this thread; great work! Thanks for sharing so much info from all your work on this lens. I recently decided to dive into anamorphic shooting and this thread was invaluable.
My setup is typical:
GH5
Taking lens (Helios 44 58mm/Minolta 55mm/Fujinon 55mm)
B&H with Redstan clamp
Here's the setup, showing the lenses mounted on some rails; taking a cue from Bold (well, more than just one), I've used some telescope guide rails attached to a smallrig clamp. But I think I prefer using the standard smallrig V-shaped lens support you can see in the image. This is because I'm actually finding this setup to be dual focus; that is, I can't get anything in focus with the taking lens set to infinity, I have to keep it around 1.5-2m and work the B&H focus from there. I know it's supposed to be single focus, so I'm not sure why this is the case or if there is something wrong with my B&H (it's pretty beat up, as you can see). As such, the B&H moves forward and back as I adjust the focus on the taking lens.
Anyway, here are the first couple shots I've taken with this setup. All are with the Helios 44, except the Kodak camera shot, which was taken with the Minolta. I plan to do some more comparative tests with different taking lenses soon.
