I should have mentioned I don't have adobe, I"m using Aperture 3...so, either need a plug in for that, or standalone.Open source would be preferable. I've read that UFRaw would do it...but can't seem to find a version of that for 5D3 and this lens...so, still looking.

when searching on the web use "samyang" as brans instead...and the correction will be with lens itself. With Adobe, each camera you register, has it's own lens library.Sure, apples and oranges, but same principle I will assuume, as I don't use Aperture.

$25 for the license. Gets you a standalone app and a plug-in for either Aperture or Lightroom. Only nitpick for me is the result is a tiff file that's double the size of the raw. Time to correct the file on my three-year-old MacBook Pro is about five seconds.

Thanks!!

I"ve downloaded PTLense...using the 10 free trial images you can do...so far is pretty good.I think I'll spot for the $25..seems to be a good tool, and images are looking good.

I'm guessing that best workflow for this, is to do all your adjustments first, and use PTLens as the final piece before exporting out as jpg or keeping as tiff?
