    What do you all use to correct for distortion for UWA lenses? I use Lightroom 5 and messed around with the "Lens Correction" --> "Transform" --> "Distortion" section of the program, but are there other better options? It seems like I have to constrain crop and I lose some of the width of the pictures...

    any help appreciated!

    EDIT: actually, I'm interested in this question not just for the 9mm BCL but for something like the 7.5, 7-14, 9-18, etc. I just happen to be using the 9mm BCL as I do not own those lenses (yet! :smile:)

    Any fisheye distortion correction will crop the image. The 9-18 and 7-14 are rectilinear lenses and this is not an issue.

    I like the fisheye look sometimes.

    I also have the 9mm BCL and Lightroom 5.

    I use the Sigma 10mm profile which works very well (you find it in the Lens correction panel -> profile tab and then in the drop down list). It does stretch out the corners and crop out a fair bit but you wont get away from that if you want to correct the distortion...

    Sometimes I just manually transform a bit if the full correction is too much (Lens correction panel -> manual tab)

    Often I leave them as they are if it suits the subject.
