Brian,
Do you find that the Bertele is both more contrasty and slightly darker than the uncoated 5cm f2 Sonnar? With the uncoated Sonnar when processing for dehaze in capture One I typically need to increase exposure by 3/4 stop.
Note: I did not do it in the glass shot as there was no haze problem.
