First test run with the Samyang 135. There's a clear tilt issue—either the belt is too tight or there's some misalignment somewhere. I'll figure it out; I don't think it's anything critical. I covered the lens hood to prevent any flare for sure, installed step-down rings from 77mm to 55mm, and left the aperture wide open at f/2 to avoid diffraction spikes. Overall, there's something to work with.

Usually these lenses have some play in the bayonet mount. You need to secure it additionally, and in the correct position. I didn't have the patience for such hassles ;)
And you can stop down the aperture with rings on the front, which improves the image and avoids diffraction spikes. Just place the ring as close to the lens as possible, though you lose the main advantage of this little lens. The SV535 105/2.8 is more interesting in this regard, but its back focus is too short. There's no perfect option in our line of work...

I installed the rings right away—I didn’t even try without them. Overall, these kinds of setups are one big compromise, and ideally you’d want a monochrome sensor with it because of the per-channel focus shift. It’s like tinkering with an old moped: a piece of junk, but you still want to ride it. And no one can take away the joy of small victories—after all, this is all for fun. Thanks for the comments, and yes, you’re right about proper solutions like the 535.
