The Mamiya Press 150mm f/5.6 is a short telephoto lens for the Mamiya Press / Universal Press rangefinder system, designed for the 6x9 and 6x7 medium format roll-film backs used on those bodies. It served as a portrait-length and modest reach option for press, studio and field photographers working with the Press platform.

With only a single UK auction record on file, market signal for the Press 150mm f/5.6 is thin: that lone hammer result sold for £38 in 2023 at saleroom level (excluding commission), which sits at the lower end of typical Press-system glass and reflects the narrow buyer pool for this format today in 2026. Clean, fungus-free copies tend to sell for more than well-worn examples, but with this little data the lens's true worth is best treated as a wide range rather than a fixed price.
