Yes, Kurt, I like the Carl Zeiss Planar 80/2 a lot more than the Mamiya 80/1.9 for that reason. Credits go to you, to have me inspired to try the Mamiya lens (first on Mamiya bodies), finally leading me to the S2.
Here is another lens used on the S2 body - a Schneider-Kreuznach 80/2.8 Xenotar in Exakta 66 mount - this lens really shook me (I didn't expect it to be THAT good).
This is my new favourite manual focus normal lens. It is the 80 mm, I tried the Hasselblad 80/2.8 CFE to be but it never sparked me. This Xenotar though did it from the first time, I saw how it behaves.
