I have two Contax film cameras: ST and 167MT.
I also have two Carl Zeiss Contax lenses for those: 180/2.8 and 85/1.4
Problem: combination of 85/1/4 on Contax ST results in blackened and frozen viewfinder, with mirror up and LT letters in the viewfinder flashing (I assume LT stands for Long Time - 2 sec to 16 sec; and flashing means underexposure). The only thing that helps is to turn the camera off and on.
Here is the kicker: the same lens works fine on the 167MT, and what's more, the other lens, 180/2.8, works fine of ST just as well?
What gives!?
Any help appreciated.
