@johnnymcg If you don’t sent the pictures it’s almost unuseful…
Here you can find instructions for distorsion calibration that i think is the most important part:
Once you’ve got the raw images, you can upload them there.
For ca with that camera you can use autocorrection, for vignetting you need a white plexiglass that doesn’t exceed 3mm thickness, and a a lamp. You surely can find how to proceed on lensfun page, it’s really really ultraeasy.
