Anyone of the Contax users here care to find out how to correct Contax lenses with the Alpa Corrector?
Would be nice if you would try the following values. And possibly correct them.
I just selected existing profiles and modified them… trial and error.
But so far the values seem to be not too far… at least at infinity.
I think you don't have to have a P45… any sensor with crop 1.1 should be fine as this is just an approximation anyway (still better as e.g. the distortion correction in Capture One).
Planar 80
the profile for the Rodenstock50_Sinf_v1a seem to do a pretty good job
You can also use the attached profiles.
Distagon 35
This one is hard… would be glad if someone could find out some useful values :-)
The Rodenstock HR 23 is probably not too bad as a starting point
Thanks!
