idk, sigma 50mm art will give you pretty straight lines. At least straight enough for people. Why would you even mention it? Are you taking photos of line meshe

idk, sigma 50mm art will give you pretty straight lines. At least straight enough for people. Why would you even mention it? Are you taking photos of line meshes or something? Life is imperfect. Lens specs are only good for reviews / marketing because it is hard to otherwise compare lenses for there real value. I am fine with control I am getting from the big camera.
