I remember it well ... and loved it.
I also fondly remember some of the contortions I got into with that rotating prism. While working in a TV station I was asked to illustrate a story on three ladies playing violin in the resident orchestra. I shot wide open with the 120 S-Planar with quite a lot of tilt applied. I was able to shoot a section of the orchestra with just the three culprits sharp and looking in through the rotated prism while the camera was held rotated 90º.
It seems that there was a time when cameras were made to provide potential for those who cared.
Cheers,
