The Mamiya Sekor Z 110mm f/2.8 is a short telephoto prime for the Mamiya RZ67 medium format SLR system, offering a moderate field of view well suited to portraiture and general studio work. It mounts to RZ67 bodies via the system's bayonet and integrates with the camera's leaf-shutter operation, making it a common choice among RZ67 users looking for a fast standard-to-portrait length.

At UK auction, hammer prices for this lens have ranged from £150 to £580 across the recent sales on file, giving a midpoint of £365 between the two recorded results. As of 2026, what an RZ67 110mm f/2.8 is worth at saleroom level depends heavily on cosmetic and optical condition, with clean, fungus-free copies sitting at the upper end of that band and tired examples sells for considerably less.
