to database. The distortion corrections appear to work nicely over the entire range presented. The TCA for this lens varies wildly, with surprisingly little at 12mm, to quite a bit at 18mm (where it has almost no visible distortion), then varies somewhat unpredictably for the rest of the zoom range, so perfect correction at all focal lengths wasn't possible using the same calibration focal lengths as distortion. It might be possible to add more TCA correction entries, but I'm not sure if this would create more problems than it would solve... @rmonat, maybe try the profile for a while, and if there are any particulary problematic focal lengths for TCA, post about it here."}}
