The 28mm f4.5 D is a full‐frame, ultra wide lens that utilises 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 colour shift problems with digital backs (due to the extreme angle at which light rays hit the sensor), the Phase One Digital 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, colour accuracy and contrast.
Unlike conventionally designed digital lenses, the 28mm f/4.5 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 Phase One Digital AF 28mm f/4.5 D is ideal for a wide range of applications, including commercial, architectural and outdoor photography.
