Curious what might be the best for correcting lens distortion. The 2 lenses I use the most are 16-35mm f4 and the 28-300mm vr on D800E. I've seen a few, just wonder if one is any better than another. When I use the lens distortion filter in PSE I end up loosing half my image.. I'm sure's a better way. I also have LR-4 but very seldom use it.
