My new lens is the TTArtisan 75/1.5.
Many reviews of this lens are available already, so here is just some brief information about it.
M42x1/45.5 mount.
6 elements in 4 optical groups.
9 aperture blades.
58mm filter thread.
The lens has ability to adjust the scale orientation, but my new copy is oriented incorrectly.
(mounted on the Pentax Super A with a M42-Pentax K adapter, where is the focusing scale?)
To adjust it, loosen the three T5 Torx screws on the lens (as stated on the official website in the "Characteristics" section). However, I successfully used a 1.3 mm hex key. Why can't the manufacturer make these adjustments itself? They should purchase used Zenit M42 cameras to use as benchmarks.
As is typical with Chinese manual focus lenses, my copy focuses beyond infinity when the focusing ring is turned to its hard stop.
This lens is clearly a homage to the Biotar 75/1.5.

The "fat" (third) version was chosen as a reference. In my opinion, the TTArtisan 75/1.5 has an unattractive appearance. It looks especially bad when used with an adapter for a mirrorless camera.
In contrast to the Biotar, the aperture preset ring of the TTArtisan 75/1.5 is fake. There is only one aperture ring (f/1.5-f/16 with clicks).
But, at least, the TTArtisan 75/1.5 is much lighter and smaller than the Helios-40 85/1.5, which is also a Biotar relative. My Helios-40 was quite good, but impractical, so I sold it. The TTArtisan seems more usable in the real life, although I didn't consider it as a replacement for the Biotar 75/1.5. Its character seems to be different.
