I just applied the lens profile in Lightroom to "correct" the fisheye view to rectilinear... Nothing fancy.
For me, the takeaway was: not much gained on the wide end of ff once you get down to extremely wide focal lengths, but you don't want fisheye & so you have to correct distortion/crop into image. I've been shooting lots of interiors lately, seems like doing that with 8mm could be a bit much, probably exteriors & astral photos are more suited. -c On May 2, 2016, at 5:38 PM, Darren Addy <pixelsmi...@gmail.com> wrote: Very interesting demonstration, Christine. Thanks for sharing it. What method of "correction" for the fisheye did you use? This makes me look a bit differently at the Samyang 8mm fisheye (on a full frame). I'm not usually terribly interested in fisheye lines, but if it gets one wider (corrected)....
