Enhancement Idea - Use lensfun to fix lens distortion

[supertobi]

It would be really cool, if you would use lensfun to use the distortion in your calculation. This would led to bended lines according to the distortion of the lens. Is this possible, what do you think?

Nice! I was about to write a very similar comment / request regarding lens distortion. fSpy would become the one-stop solution. Even better if it supported calibrating your own lenses that aren't yet in the database (e.g. like Hugin offers it via line detection http://libregraphicsworld.org/blog/entry/creating-lens-distorsion-models-with-hugin-lens-calibrator )
