How do you do lens distortion?
One of the easiest ways to spot lens distortion is to attach a wide-angle lens, or shoot at the wide end of a zoom lens. The wider angled the lens, the more curved that straight lines will appear, as you can see with the distorted edges in the image below, taken with an otherwise good-quality, 24-70mm f/2.8 zoom.
How do you fix camera lens distortion?
You can change your position and shoot from a spot further away from your subject with the same lens.

The first type of distortion is when a lens “accidentally” makes a straight line curve or wobble when it should be straight.
