Lens OverviewSchneider-Kreuznach 80mm f/2.8 LS

The Schneider-Kreuznach AF 80mm f/2.8 LS is a prime medium format lens designed specifically for Phase One camera systems. Built around an 80mm focal length, it sits in the standard range for medium format shooting, making it a natural choice for portrait, editorial, and general studio work where a balanced perspective is desirable. The lens opens to a maximum aperture of f/2.8, providing meaningful light-gathering capability for a medium format prime.

One of its defining characteristics is the built-in leaf shutter mechanism, which the LS designation directly references — this allows for flash synchronization across a broader range of shutter speeds compared to focal-plane shutter systems, a significant practical advantage in controlled lighting environments. The lens supports both autofocus and manual focus operation, giving photographers flexibility depending on their shooting style or subject. It accepts 72mm filters, and comes in at 500g, which is a manageable weight for a medium format prime.

There is no image stabilization included, which is consistent with studio-oriented lenses of this type. The Phase One mount ensures direct, native compatibility with Phase One digital backs and bodies.
