I tried many lenses with M42-MFT noname speedbooster (not original) on BMPCC. But they are all too long focus for my taste.
Helios 44-2 (USSR) - Image is ideal. Tricky aperture, clicks while focusing.
Jupiter 37A (USSR) - Image is ideal.
Sirius MC Auto Zoom 28-70 (Japan) Image is near-ideal (cold tones). This my favorite M42 lens. Looks parfocal. Quite a funny computer that keeps the aperture constant.
Prakticar MC Auto Zoom 28-70 - Image is near-ideal (Chromatic aberration). Remounted to M42, needed to machine the body. There are right and left models, I have both. Looks parfocal.
Hoya HMC Wide Auto 28mm - image is ideal
Promaster Spectrum 7 28-210. Too soft. Remounted to M42, remount is reversible. Modified to macro tele zoom. Tuned to parfocal with shims, no idea how to tune officially.
You could use the M42-EF adapter (preferably with the focus confirm chip) with EF speed booster or EF camera (it's exactly what I am going to do when I obtain an Ursa of any model since M42 is my base mount)
