The Mamiya TLR 105mm f/3.5 is a short telephoto lens pair designed for the Mamiya C-series twin-lens reflex system, fitting bodies such as the C220, C330 and their variants. With a 105mm focal length and f/3.5 maximum aperture, it was intended as a portrait and medium-range option sitting between the standard 80mm and the longer 135mm and 180mm Sekors. Like all Mamiya TLR optics, it carries a leaf shutter built into the taking lens and uses the bayonet mount shared across the C-series.

At recent UK auction, hammer prices for this lens pair have ranged from around £40 to £120, giving a midpoint near £80 based on the limited saleroom data available through 2026. These are wholesale-level results achieved on the hammer rather than dealer retail, so clean, fully-working copies can sell for more once serviced and offered through specialist shops. Condition — particularly clear glass and a reliable shutter — is the main factor that decides what a given example is worth.
