|DISTAGON||Retrofocus lens based on asymmetric Distagon optical design. First Distagon appeared in 1953, the optical scheme has evolved since then and is now used not only in Carl Zeiss lens.|
|T*||The multi-layer coating is applied to the surface of lens elements. It boosts light transmission, ensures sharp and high contrast images, minimizes ghosting and flares.|

Design and Features
The 28 mm Distagon® T* f/2 closes a gap in the line of the top lenses for the single-lens camera in the wide-angle range. It has been found that in many a case it is something of a leap from focal length 35 mm - angular field 62 degrees - to focal length 25 mm - angular field 80 degrees. The ratio of the object fields is 1:2, the same applies for the depth of field - provided the same stop is used. The demanding photographer may therefore find himself in situations requiring a lens which has at least an initial aperture of 1:2 at an angular field as large as possible and which at the same time provides pictures with greater depth of field than does the deservedly popular 35 mm lens.
The task of developing a lens with 28 mm focal length and an angular field of 74 degrees and giving it excellent image quality despite the exceptionally large initial aperture of 1:2 for this focal length was admirably solved with this Distagon® lens. The image quality is surprisingly uniform over the entire field up to the format corners. To make the lens usable in the near range as far as possible one group is moved in relation to the rest of the lens during distance setting. The loss in image quality in the outer parts of the picture, otherwise disturbing, is largely compensated by this measure.
The lens incorporates a floating system that provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. Learn more
