I have been trying the various lens profiles in Lightroom to see which would do the best job to defish the Oly 8mm f/1.8 I just purchased. To me it looks like the Samyang 8mm f/2.8 UMC fisheye profile. The Bower and the Rokinon are close but, interestingly, not identical despite the fact that, I thought, all three brands come out of the same factory. Wondering what profiles you like and why. Don't want to go to all the manual machinations to defish - looking for a simple, one-click solution that is pretty (or maybe very) good. Thanks.
