Manufacturer description #1

ELMSFORD, NY: Mamiya America Corporation announces the addition of the new world-class MF (Manual Focus) 120mm f/4 Macro/Portrait telephoto lens with focus confirmation for the Mamiya 645 Autofocus camera, expanding the system to nine lenses.

With an angle of view of 33 degrees, this lens is equivalent to a 73mm focal length in 35mm format. Pinpoint sharpness with manual focus is assured from infinity to 1:1 magnification without additional adapters by a green diode in the finder providing focus confirmation, This lens provides a flattering perspective suitable for even tight portraits, and permits good working distances, in or out of the studio, for anything from extreme detailed close-ups to full-length portraits is manually focused (MF) and utilizes focus confirmation in the Mamiya 645AF 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.

Mamiya uses eco-glass, which contains no lead or arsenic, maintaining the company's "Earth-friendly, Nature-friendly" policy.

The Mamiya 645 AF 120mm f/4 Macro/Portrait MF lens comes with a lens hood and will be available for shipment in late November 2000.

Manufacturer description #2

With an angle of view of 33 degrees this versatile lens offers the perspective of a 73mm focal length in the 35mm format, ideal for portraiture, landscapes or general photography. Pinpoint sharpness with manual focus is assured from infinity to 1:1 magnification by a green diode in the finder providing focus confirmation. Lens elements of anomalous dispersion glass equal APO lens performance in terms of contrast, resolution and correction of color aberrations for superior image reproduction. A floating mechanism assures uniform sharpness from center to the corners.
