Canon EF 28mm lens
Canon Inc. has produced two different 28 mm lenses for its Canon EF lens mount. Both are currently available.[1]
When used on a digital EOS body with a field of view compensation factor of 1.6x, such as the Canon EOS 450D, 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 an 36 mm lens mounted on a 35 mm frame body.
- Canon EF 28mm f/1.8 lens, introduced September 1995.[2]
- Canon EF 28mm f/2.8 lens, introduced April 1987.[3]
With the discontinuation of the EF 15mm Fisheye Lens in 2011 the EF 28mm f/2.8 lens became the oldest EOS lens still in production.[4] [5]
