With an angle of view of 33 degrees, the 120mm f/4 Macro MF Digital Lens is equivalent to a 73mm focal length in 35mm format. Pinpoint sharpness with manual focus is confirmed from infinity to 1:1 magnification, without additional adapters, by a green diode in the finder. This lens provides a flattering perspective suitable for tight portraits, and permits good working distances in or out of the studio. It can be used for anything from extreme detailed close-ups to full-length portraits. The lens is manually focused (MF) and utilizes the digital focus confirmation in the Phase One 645 AF body plus auto-diaphragm operation.
Anomalous dispersion optical glass is employed to reduce chromatic aberrations, which results in APO-quality lens performance when focused from infinity to 1:2 magnification, and significantly reduces chromatic aberration from 1:2 to 1:1 magnification. The optical engineering and multi-coatings of this lens achieve excellent color balance, high contrast and high resolution over the entire focusing range, which is an extraordinary accomplishment for a Macro lens. The barrel design reduces flare significantly.
