nikkor, rodenstock 305mm or fuji, can't go wrong.

I'm talking about barrel distortion that causes verticals/horizontals to bow or bend. I've read that some 300mm lenses do exhibit some barrel distortion, and given that I shoot a lot of subjects with strong vertical/horizontal lines, I want to be sure that I'm getting the lens with least distortion.
