Lens Overview — Mamiya Phase One 110mm f/2.8 LS AF

The Mamiya Phase One Schneider 110mm f/2.8 LS AF Lens is a prime medium format optic built for professional photographers working within the Mamiya 645 mount ecosystem. As a 110mm prime, it sits in the standard focal length range for medium format, making it a natural choice for portraiture, editorial work, and studio photography where subject rendering and background separation are priorities. With a maximum aperture of f/2.8, it offers a meaningful degree of light-gathering capability for a medium format lens, giving photographers more flexibility in controlled lighting environments and allowing for a shallower depth of field.

The lens supports both autofocus and manual focus, providing versatility across different shooting scenarios and working styles. A 72mm filter thread makes it straightforward to attach commonly available circular filters for creative or technical purposes. Weighing in at 935g, this is a substantial but expected heft for a medium format prime of this class.

Image stabilization is not included, so stable shooting technique or appropriate support equipment is worth considering, particularly in lower-light situations. Overall, this lens is purpose-built for the Mamiya 645 system and targets photographers who prioritize the rendering characteristics and format size that medium format delivers.
