It's possible... the different aspect ratio might want an adjusted crop factor, though. > This seems like a good solution for now.

The situation with providing profiles for these kinds of devices gets more complicated all the time, as they invent new ways to play with the captured image data before baking it into an image (or video) file. Different croppings, different corrections... and in some cases digital stabilization that may involve yet another different crop factor, and moves the image circle and its distortions around within the frame... who knows what else. If somebody wants to try to maintain that corner of the database, more power to them, but it's not really the thing I'm personally most likely to spend time banging my head against. ;) -- jys _______________________________________________ Lensfun-users mailing list Lensfun-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lensfun-users
