Nope I was heavily into the Pentacon Six/EX66 system at the time for focal plane MF. But I was daring enough to use those on commercial assignments without ever a fail. As a supplement to my Hasselblads.

Later I gravitated away from the P6 and sold the 120 & 150 set to my internet friend "Mr. Pentacon Six". He documented these lenses configured by Glenn Evans on his extensive P6 website.
