Either type of distortion table superimposes a matrix of lines or dots representing the distorted image over an equivalent undistorted matrix. These charts make it very easy to gauge distortion levels at certain points in a frame. Distortion is not linear, and thus optical distortion tables are effective when accounting for field of view.

When accounting for levels of distortion in optics, there are a few different ways to read and measure its effects. Understanding distortion tables can help decide lens selection and lens specifications.

TV distortion, on the other hand, measures distortion based on a single square plane filling the vertical field of view. The resulting graphic can resemble a television screen. TV distortion tables measure the “straightness” of a line (or lack thereof) against the edge of a lens. While this method is effective for measuring within a given field of view, it does not account for distortion levels beyond that field of view.

However, distortion actually has a more specific definition and refers to a certain type of photographic aberration. Understanding what distortion is, and how to measure it, can be very helpful when trying to determine the right lens for the right application.

Pincushion distortion has the opposite effect, causing straight lines to bend inward toward the center. The result is an image shape resembling that of a pincushion.

This is a list of large sensor fixed-lens cameras, also known as premium compact cameras or high-end point-and-shoot cameras. These are digital cameras with a non-interchangeable lens and a 1.0‑type (“1‑inch”) image sensor or larger, excluding smartphones and camcorders.

Without a lens mount, a substantial portion of the lens assembly can be fitted inside of the camera body right up to the sensor. This makes it possible to fit a larger sensor or a lens with a larger aperture compared to a camera and interchangeable lens combination of similar size.

But in some cases, distortion can have a negative impact on image quality. This is especially true for highly technical applications, such as architecture photography or medical imaging. In these fields, reducing distortion is a top priority.

Distortion tables, or distortion charts, are tools used to measure distortion levels with certain lenses. Once again, there are two general categories for measuring distortions: Optical and TV distortion.

What distortion actually refers to is the bending of lines in an image that, in reality, are actually straight. Distortion is usually unavoidable with most lenses, though in many cases it is hardly perceptible at all.

“Distortion” might be the most widely misunderstood, or misused, word when it comes to optics. Many people will use “distortion” to refer to any aberration or error in a photographed image.

Almost all zoom models with larger sensors have been discontinued in favor of their interchangeable lens counterparts that offer more flexibility.

Current compact models market themselves as vlogging cameras (e.g. Sony ZV-1 series and Canon G7 X series) or travel zoom cameras (e.g. Sony RX100 series and Panasonic ZS series), emphasizing functionality that smartphone cameras still lack.

Pincushiondistortion

Distortion can affect the appearance of any image on any lens. Adjusting for field of vision can lessen distortion levels, but that alone does not eliminate distortion. The best way to minimize distortion is to use specialized equipment and advanced, customized lenses for exact image quality.

With barrel distortion, straight lines appear to bend outward, away from the center of the image. It is called barrel distortion because the effect can cause a geometric square image to take on the shape of a barrel.

The Leica Q series, Fujifilm X100 series, and Ricoh GR series are popular cameras in this category. This list excludes cameras with removable sensors, such as the Phase One XC.

Optical distortion measures the space between where an object appears in a frame versus where it appears in reality, or where it should be. Optical distortion can be easily read using a distortion dot chart, or a lattice pattern chart.
