User Ratings & Reviews:

Phase One Digital lenses are designed for maximum image quality and freedom of choice.  When used with the Phase One P+ digital backs, the image quality is further enhanced through advanced digital optimization in Capture One, the professional raw processing software supplied from Phase One.

Not only have all lenses have been measured and profiled for automated enhancement in Capture One, also data regarding the specific position of the lens elements are captured and used for image optimization. This leads to absolute leading image quality with unique replication of the true colors, details and lightning of the captured moment. Phase One Digital lenses uses ecoglass, which contains no lead or arsenic,  securing both better image quality and a nature-friendly policy.

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 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, color 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. back.
