Canon EF 28mm lens
These lenses use the EF type mount that fits the Canon EOS line of cameras. When used on a camera body with an APS-C sensor, such as the Canon EOS 700D, it provides a narrower field of view, equivalent to a 45 mm lens mounted on a 35 mm frame body. With a 1.3x body such as the Canon EOS-1D Mark III, it provides a less narrow field of view, equivalent to a 36 mm lens mounted on a 35 mm frame body.
Three EF 28mm lenses have been sold by Canon:
- f/2.8, introduced April 1987 (now discontinued, replaced by f/2.8 IS USM)
- f/1.8 USM, introduced September 1995
- f/2.8 IS USM introduced June 2012
With the discontinuation of the EF 15mm Fisheye Lens in 2011, the EF 28mm f/2.8 lens became the oldest EOS lens in production before being itself discontinued after the release of the IS version. The IS version marked another milestone for Canon; that lens and the 24mm f/2.8 IS lens introduced at the same time were Canon's first image-stabilized prime lenses with a focal length less than 100 mm, as well as the company's first image-stabilized non-L primes.
