Phase One has added two new Schneider Kreuznach lenses to its range of optics, introducing the Blue Ring 40-80mm LS f/4.0-5.6 and 75-150mm LS f/4.0-5.6 zoom lenses.

Both Blue Ring zoom lenses feature front glass elements, with front lens diameters of 63mm and 65mm respectively, which Phase One says delivers edge-to-edge coverage of full frame 645 format.

When used on a Phase One XF 100MP system camera, the new Schneider Kreuznach lenses are able to capture a  full 100-megapixel image.

Together, the Schneider Kreuznach 40-80mm LS f/4.0-5.6 and 75-150mm LS f/4.0-5.6 zoom lenses comprise an effective zoom range from 40mm to 150mm.

Each Blue Ring lens features a zoom lock function on its barrel to help photographers maintain focus position while zooming. Each lens also supports flash synchronization up to 1/1600s. 

What’s more, new built-in electronics allow for individual focus calibration when used with the Phase One XF Camera System.

“A Phase One full frame 100MP medium format sensor is 1.5 times larger than the cropped size 50MP medium format and 2.5 times larger than sensors found in high-end 35mm DSLRs,” said Espen Beck, Phase One Senior Product Manager.

“Capturing the full resolution of a square sensor this size with a round lens and avoiding crop means that the entire lens must be larger, which requires larger movements of individual lens elements while meeting the requisite standards for speed and precision.

Availability and Pricing

The two new Blue Ring Zoom lenses are available now and compatible with the Phase One XF, Phase One 645DF+ and Mamiya 645DF+ or DF camera systems.

The Schneider Kreuznach 75-150mm LS f/4.0–5.6 Zoom price tag is €5.490 / $5,990, and the Schneider Kreuznach 40-80mmLS f/4.0–5.6 Zoom price tag is €7.990 EUR / $8,990.
