About this item

Mamiya's series of high-resolution medium format lenses is designed for use in the digital and film-based world. The Mamiya Sekor Zoom AF 75-150mm f/4.5 D and the Mamiya Sekor AF 28mm f/4.5 D Aspherical lenses have been designed specifically to direct light onto the digital sensor at an angle that is ideal for digital photography. The resolving power of the lenses also corresponds perfectly with a high megapixel sensor. Autofocus and manual focus functions are easily selected with one-touch action. Simply move the focusing ring backwards or forwards.

Mamiya Sekor lenses have been admired by both medium format and 35mm film camera users for their superior quality and now this legacy will continue as Mamiya meets and exceeds current optical standards for modern photographic lenses.

Mamiya Sekor AF 28mm f/4.5 D Aspherical
This full-frame ultra wide angle lens is the world's first medium format 28mm lens that can be used for film and digital backs. The use of aspheric lens elements produces outstanding optical performance.

The 28mm f4.5 D is a full-frame, ultrawide lens that utilizes the latest aspheric lens technology to produce high resolution and large image circle coverage for film and digital backs. Since wide angle lenses can cause color shift problems with digital backs (due to the extreme angle at which light rays hit the sensor), the Mamiya 28mm f/4.5 D has been designed to direct light rays so that they are parallel when they hit the sensor producing maximum sharpness, color accuracy and contrast.

Unlike conventionally designed digital lenses, the 28mm f/4.5 Sekor D Aspherical was designed with the requirement that it works with digital and film systems. It is the world's first 28mm medium format lens with this capability. The Mamiya Sekor AF 28mm f/4.5 D is ideal for a wide range of applications, including commercial, architectural and outdoor photography.
