Lenses For Medium-Format D-SLRs
lens for upgradeOf course, the digital SLRs based on the 35mm SLR form factor aren’t the only D-SLRs. There also are D-SLRs based on medium-format cameras from the likes of Hasselblad, Leaf, Mamiya, Phase One and Sinar. These have evolved from digital backs attached to medium-format film cameras into complete dedicated digital camera systems. Each system offers a line of lenses designed and optimized specifically for that system.

With bodies costing from $12,000 to more than $40,000, these are definitely pro tools, and the lenses are all pro lenses, which simplifies the lens decision-making process considerably—just get the one(s) for your system that provide(s) the focal length(s) you need.

Hasselblad’s H3D system consists of bodies with resolutions from 31 to 50 megapixels, and 11 HC and HCD lenses. The HCD lenses are digital-only units designed specifically for the H3D system. Focal lengths range from 28mm ƒ/4 (with a remarkable-for-medium-format, 95-degree angle of view) to 300mm ƒ/4.5. There’s also a 1.7x teleconverter, an HTS 1.5 tilt-shift adapter and a CF adapter for old Hasselblad film-camera lenses.

Leaf and Sinar market a medium-format D-SLR developed with Jenoptik that accepts their respective medium-format digital backs, from 28 to 56 megapixels. These cameras—the Leaf AFi-II and Sinar Hy6 65 in most recent form—use Schneider AFD (AutoFocus Digital) lenses specifically designed for them. These range from 40mm through 250mm.

Mamiya and Phase One offer the 645AFD III camera (each under the company’s own name), with backs from 16 to 60 megapixels. They use Phase One-branded (Mamiya-manufactured) Digital AF lenses designed for them (plus a manual-focus Phase One 120mm ƒ/4 macro lens) and a wide range of Mamiya 645-format lenses. The Digital AF lenses range from a 28mm ƒ/4.5 to a 150mm ƒ/2.8 tele, including a 75-150mm ƒ/4.5 zoom.
