Hi,
here is the calibration file for my Cosina 19-35 1:3.5-4.5 MC.
This lens is also labeled as Soligor,Vivitar and Voigländer.
Pictures were taken with a Canon 5d.

Thank you for the contribution! With which method did you obtain the vignetting data? A diffusor?

What does "cpp error corrected" mean?

sorry I meant ccp error (Cut Copy Paste)
There was wrong values for 35mm focal length distortion and all distortion values have now more decimal precision
