I tested almost all of my 50mm lenses. It would take quite a lot of time to make comparision table, like for the 135mm lenses (maybe later), so I'll only post short summary. Maybe some people will hate me after reading this:
Tested lenses:
1. Voigtlander Color-Ultron
2. MC Pancolar 50/1.8 (Zeiss made)
3. MC Pancolar 50/1.8 (Pentacon made)
4. Pancolar 55/1.4
5. MC Pentacon 50/1.8
6. Biotar T 58/2
7. Primoplan V 58/1.9
8. Trioplan 50/2.9
9. S-M-C Takumar 50/1.4
10. S-M-C Macro 50/4.0
11. MC Cosinon 55/1.4 (Tomioka 55/1.4)
12. Tomioka Yashinon 55/1.2
13. Helios 77M 50/1.8
14. Helios MC 44-3 58/2
15. MC Volna 50/2.8 Macro
16. Industar 50-2 50/3.5
I'll speak only about axial ("bokeh") CA - nothing more.
- almost all fast lenses are pretty craps
- all Biotar-based lenses are craps, too (Biotars, Helioses)
- Pentacon-made Pancolar is Pancolar optically
- Pancolar and Ultron are worse than Pentacon
- for some lenses helps to stop them down a bit, but slower lenses are generally a bit better
- the only acceptable results under f/2 produced Pentacon 50/1.8 and Primoplan 58/1.9 (both lenses are Meyer designs!)
- as for f/1.2 and f/1.4 lenses, all of them are equal (crappy wide-opened), at f/2.8 the best is Pancolar 55/1.4, the worst Tomioka 55/1.2. Cosinon and Takumar are very similar.
- the best (almost apochromatic) are the cheapest lenses: Industar 50-3.5 and Meyer Trioplan 50/2.9
- 2nd place: Volna-9 Macro 50/2.8 and S-M-C Macro Takumar 50/4
- 3rd place: Pentacon MC 50/1.8 and Meyer Primoplan 58/1.9
- huge disillusion: all Zeiss lenses
I'm awaiting, that some members will say, that I can have bad copy of... etc. - thats exactly what I'm reading anytime when any Zeiss lens is outperformed by any other lens (Pancolar 50/1.8 by Takumar 50/1.4, Sonnar 135/3.5 by Jupiter 37AM 135/3.5 etc.). No, I have 3 Pancolars 50/1.8, 2 Pancolars 55/1.4, 3 Sonnars 135/3.5 and there are no optical differences between those coppies. There are simply some lenses, which can be better in some ways than Zeiss lenses

HI!!
Excelent job. Thanks, it's very informative.
Thanks for sharing yor time and effort with us.
I don't know what importance has these dates into the IQ, perhaps a lot.
I recognize that when I did (laboratory did) a copy of @ 100 x 70 taken with 1,8/50 pancolar showing a tourist favorite bridge, it had a green band at the brigde contours. At 30 x 40 I had not problems.
All of my copies of pentacon 1,8/50 didn't and don't outperformer the IQ of my copies of pancolar 1,8/50. The inverse is.
For me, 1,8/50 Pancolar outperformer the 1,4/50 tak in sharpness at F/8, 11 and 16, both equals at F/5,6 and Tak better at F/2, 2.8 and 4. Both craps at F/1,8. Bokeh, i like panc more.
I can't collaborate with nothing else. Rino. _________________ Konica 2,8/100
