Hi,
I just created distortion (manually with hugin) and tcs calibration for the 24-70 f/4.0 S lens for the new Nikon Z mount. IMHO it didn't really fit into one of the existing database xmls, since it's not a slr but the first mirrorless system from Nikon so I created a new slm-nikon.xml which also includes the new cameras and the Z mount. Hope you can integrate it in the official release soon.
Thanks for this great project! I really appreciate being able to give something back to the community. Hopefully I find some time and setup to also add the vignette calibration soon. :)
Regards,
Philipp
