The 28mm f/4.5 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 ideal for a wide range of applications, including commercial, architectural and outdoor photography.
