Pincushion Distortion - This distortion causes the image to bend inward towards the center.

Pincushion Distortion
The opposite of barrel distortion; straight lines are bowed in toward the middle to resemble the sides of a pincushion; present in smal amounts in some telephoto and telephoto-zoom lenses.

Pincushion distortion - a type of lens distortion which causes images to bow inwards on the horizontal and vertical planes.
Pincushion distortion
A lens aberration or defect that causes straight lines to bow inward toward the center of the image.
pincushion distortion
an image that compressed toward the center with distortion most noticeable at the center of horizonal or vertical edges.

Pincushion Distortion
An optical distortion, common in less expensive lenses, where parallel lines on the horizontal and/or vertical plane bow inward. Pincushion distortion is the opposite of barrel distortion.

Barrel & pincushion distortion
Lens technology has come a long way since the days of simple point and shoot cameras of a few years ago.
Bridge cameras often have superzoom lenses which provide a very wide zoom range, typically between 10:1 and 18:1, which is attained at the cost of some distortions, including barrel and pincushion distortion, ...
There are two types of distortion--barrel distortion and pincushion distortion. Distortion cannot be improved by stopping down the lens.
The common characteristic of a zoom lens is that is shows barrel distortions at the wide end of its zoom range and pincushion distortions at the long end. Somewhere in between there's usually a small range that is free of distortions.
It did a great job of correcting the consequences of lens defects such as barrel and pincushion distortion, chromatic aberration, vignetting and blur, but there was no way I could justify buying it.
Drag to the left to correct pincushion distortion and straighten lines that bend toward the center.
Vertical - corrects perspective caused by tilting the camera up or down. Makes vertical lines appear parallel.
One unintended distortion that's pretty common today is barrel distortion where straight lines away from the center of the photo bow outward (less common is pincushion distortion where the lines bow inward).
Of course just like the fact that rectilinear lenses are rarely ever truly rectilinear (they suffer from barrel and pincushion distortion), so fisheye lenses usually don't follow the exact mapping suggested by these equations.
Lens distortion causing straight lines to "barrel" out; the opposite effect is Pincushion Distortion. Fairly common to some extent in cheaper lenses (and some expensive ones).

spherical aberration, chromatic aberration, barrel distortion, pincushion distortion, and diffraction). All lenses have design and material limitations. Thus, the camera optics distort (i.e., manipulate) the scene that is captured.
The camera and lens specific distortion profiles fix common lens perspective issues like barrel and pincushion distortion. Also included in the lens correction tool group is a tool to correct chromatic aberration and a vignette control tool.
-Curvilinear distortion - combination of barrel distortion and pincushion distortion.
-Curvature of field - lens aberration causing a curved plane of focus.
Lens Distortion: An abnormal rendering of lines in an image; most commonly they may appear to be bending inward (pincushion distortion) or outward (barrel distortion). Correctable by using a plug-in in an imaging program.
UPDATE 12/05: I really like the new Nikon 18-200 as a "travel" lens and may start taking it instead of the 24-120VR. Of course it is slow & has barrel/pincushion distortion, ...
The two main types of lens distortion are: (1) Barrel distortion, in which the straight lines near the edges of the viewframe appear bowed outward from the center, like a barrel-shape; and (2) Pincushion distortion in which the same lines bend in ...
The most common types of image distortions are 'barrel' and 'pincushion'. Barrel distortion will make a rectangular subject appear swollen in the middle while pincushion distortion will make it appear pinched.
