{"overview":"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.","market_narrative":"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.","buying_guide":"Inspect both the viewing and taking lenses for fungus, haze and coating scratches, since TLR pairs often show cosmetic wear on the front viewing element from decades of use. Check the taking lens for oil on the aperture blades and confirm the leaf shutter fires accurately at all speeds, especially the slow ones, as sticky shutters are the most common fault on this generation. Focus helicoid movement should be smooth without grit, and look for any signs of element separation at the edges of the cemented groups.","specs":"Documented specifications are limited to the 105mm focal length, f\/3.5 maximum aperture and Mamiya C-series TLR bayonet mount.","faq":[{"q":"How much does a Mamiya TLR 105mm f\/3.5 sell for?","a":"UK auction hammer results have fallen between roughly £40 and £120, with condition and completeness driving where a given copy lands in that range."},{"q":"What is a Mamiya TLR 105mm f\/3.5 worth today?","a":"Based on the small sample of verified sales, the typical saleroom value sits around £80, though a tired copy with shutter or glass issues will go for less and a clean, fully-working pair for more."},{"q":"Is the price affected by which Mamiya TLR body it fits?","a":"No — the lens uses the standard C-series bayonet and mounts on C220, C330 and related bodies, so the price is driven by optical and mechanical condition rather than body compatibility."}],"confidence":40,"reasoning":"Only two sales records are available and no specification or variant data was provided, so the market range is indicative rather than statistically robust."}
