Canon EF 28mm lens

The EF 28mm lenses are a group of prime lenses made by Canon that share the same focal length.

The Canon EF 28mm f/1.8 USM 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)[1]
• f/1.8 USM, introduced September 1995[2]
• f/2.8 IS USM introduced June 2012[3]

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.[4][5] 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,[6] as well as the company's first image-stabilized non-L primes.
