What is a rectilinear wide-angle lens?
In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the edges of walls of buildings, appear with straight lines, as opposed to being curved. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.
What is rectilinear photography?

How can you tell the distortion of a lens?
Barrel distortion describes a type of distortion wherein lines that are straight in real life appear to curve inwards (like the walls of a barrel). A good way to check for barrel distortion is to look for parallel lines in the area you are shooting and see if the lines appear parallel in your image.28 Sept 2021

What is the difference between a fish eye lens and a wide-angle lens?
Fisheye lenses also fall under the wide angle lens category, but the difference lies in the barrel distortion. A fisheye is an ultra-wide angle lens with an angle of view of around 100 to 180 degrees that produces a circular rather than a rectilinear image due to the visual distortion created by the lens.29 Jun 2021
What is the opposite of fisheye?
The opposite of a fisheye is a rectilinear lens. Distortion of a fisheye lenses is not barrel distortion, it is that a different projection or mapping is obtained by design. Angles are usually preserved but not straight lines, unless they pass through the center of the frame.22 Apr 2017
