Resolution was the maximum for 16:9 capture: 1728x972. This can be increased to 1728 x 1152 if you shoot in 3:2 (max resolution the 7D can achieve without x3 crop AFAIK). I may well shoot in 3:2 for a future video, the cost being some black bars on the sides.
I don't touch any buffer settings as I've not encountered any problems with continous recording. I have however changed the liveview settings to use canons view (this stops magic lantern from putting the liveview to black and white when zooming in to confirm focus)

The 44-2 works perfectly on a full frame body, though don't expect razor sharp corners wide open (even my APS-C gets soft around the edge at F2) so you may find F5.6+ works better if global sharpness is a big concern.
you will need an M42 to canon EF adapter. these can be bought very inexpensively, mine was made by Neewer.

Cheers!

The 44-2 is a very capable lens for video.
Having the stepless aperture ring is nice, and the focus ring is as smooth as butter.
IQ is very good, some of the sharpest old glass in it's price range.
Build quality is outstanding, no rattles or loose parts - you could practically use it as a hammer, lol.

Some things to note:
Stepless aperture is easy to nudge so be aware.
Focus ring has a long travel (270 degrees) so you get a work out pulling focus.
there is an unpainted ring inside the 44-2 that causes flaring wide open, stop down a step and it fixes it.

Overall a very fun lens, with a very fun price tag. I paid £30 for mine and the only time it leaves my 7D is when I need to get close and use my Sigma Superwide II 24mm
I shoot 10 bit @ 23.976p (low jello mode) on DForts may build.

Hi!
First post here, been lurking a few months trying to learn everything I can about ML and I think it's time to show off some 10 bit footage!
A big shoutout to Dfort, thank you for everything you've put into these builds!

Video shot on Canon 7D
Lens was Helios 44-2 + ND
No Grade
Processing was as follows:
7D 10 bit > MLVAPP (LOG-C) > Prores 422 > Adobe Premiere (LOG-C to REC709) > 4k blow up > HEVC
