Optical Distortion: No Lens is perfect (e.g. spherical aberration, chromatic aberration, barrel distortion, pincushion distortion, and diffraction). All lenses have design and material limitations.
An optical distortion in which the image 'bows' out of square. Barrel distortion is usually associated with less-expensive wide-angle lenses and digicams, ...
This is an optical distortion common to wide angle lenses where the centre of the image appears larger than the edges. With rectangular camera formats this distortion gives rectangular subjects a barrel shape.

Lens model specific optical distortions, 'X' can be one of:
'0' - no correction
'1' - perform correction
-cX ...
Three common types of optical distortions that exist, particularly in wide angle lenses, are: Barrel distortion (where straight lines seem to bow out, as if around the sides of a barrel), Chromatic Aberration (where blue fringing is present), ...
Since I was using a telephoto lens to keep the optical distortion low, as well as to throw the background out of focus, I had to position myself about 50 feet from where Rohan would be standing.
I decided to shoot with a 50-200mm telephoto lens in order to eliminate optical distortion and have the background go somewhat soft. I then dialed in the following camera settings: ...
Normal lens (also called standard lens) refers to a camera lens that most accurately represents the angle of view, image size and lack of optical distortion that is closest to the human eye; usually a 45mm to 65mm lens.

Typical lomography cameras are deliberately low-fidelity and inexpensively constructed. Some cameras make use of multiple lenses and rainbow-colored flashes, or exhibit extreme optical distortions and even light leaks.[citation needed] ...
