Trying to be objective, but it is hardly science and of course partly subjective, I would make the following conclusions on the first set of shots.
The Meyer is the real dog here, the pancolor is not that much better, but have in some shots a nice color. A pitty since I think the Meyer lenses look sexy.
The A*85 and the DA77ltd produce very similar pictures, and they should since they have the same optical solution, with the difference that wide open the 1.4 lens has a thinner DOF and hence less of the plants etc in focus. There is probably two things going on here at the same time: the A*85/1.4 really goes quite soft wide open, then it sharpens up rapidly when you close down (which is confirmed by the later portrait shots). In addition, the thinner DOF enhance this impression. The softness wide open is probably why Pentax limited the limited
77mm to f1.8 since that optical solution is not ideal if you go further. My guess is that at the f2 shoot out, the difference will be much smaller, the A* may even surpass the 77 in sharpness.
The Takumar f1.8 and f1.9...this confirms the feeling I've got from before...and it is a bit odd that the f1.9 does so well against the f1.8 since on the paper the f1.8 should be a better lens...so what comes out of a lens is not always so easy to predict. Some simple lens solutions may be some sort of soft spot in the multidimensional space you move around in when designing a lens. Makes me want a super f1.9. Only good they may go a bit less expensive than the SMC 1.8's.
The M85/2...a limited lens before the limiteds where invented? How does this simple lens does so well against the others? While being so tiny? A mystery like the 70ltd. It's not so good reputation I suppose is only because its been compared against the f1.4 and f1.8 lenses that may be a tiny bit better. The 85/2 has been on my list to Santa Claus for a while. Better be a good boy. Please Pentax take this lens design and tweak it into a DA90ltd f2 too give the 135mm equivalent that are missing in the DA ltd line.
Asahiflex...my compliments on the portraits. Some lens shoot out threads are rather booring due to rather booring and technical test pictures (like your first set), but there are some really good portraits there with the 85/2 and 85/1.4.
