The Nikkor 13mm f/5.6 is an ultra-wide angle rectilinear lens which was manufactured by Nikon for use on Nikon 135 film format SLR cameras until 1998, at which time it was discontinued. It has been dubbed 'The Holy Grail', for its low-distortion ultra-wide capabilities. The lens was produced by Nikon only upon receipt of an order, thus making it one of the Nikon lenses with the least number manufactured.

- The Zeiss 8R Ultra Prime T2.8 is a rectilinear wide angle lens with an even slightly wider field of view, even when considering its smaller image circle.
- The Sigma 12–24mm f/4.5–5.6, introduced in 2003, a rectilinear ultra-wide zoom designed for the 35 mm format (both film and digital), providing a slightly wider field of view. The company replaced this lens in 2016 with a version offering the same focal length range but a constant maximum aperture of f/4.
- The Sigma 8–16mm, introduced in 2010, a rectilinear ultra-wide zoom designed for DSLRs with APS-C sensors, providing essentially the same 35mm equivalent field of view as the company's 12–24mm offering on full-frame.
- The Canon EF 11–24mm, introduced in 2015, a rectilinear ultra-wide zoom designed for the company's full-frame DSLRs.
- The ultra-wide camera in the iPhone 12 and later models is based upon the Nikkor 13mm, in so far as having approximately the same angle of view and complete lack of barrel distortion.
