The Mamiya TLR 250mm f/6.3 is a long telephoto lens in paired taking/viewing cell form, designed for the Mamiya C-series interchangeable-lens twin lens reflex cameras such as the C220, C330, C330f and C330s. It sits at the extreme end of the TLR system's focal range, intended for portrait compression and distant subjects on 6x6 roll film.

At recent UK auction, hammer prices for this long telephoto TLR lens have ranged from £20 to £110 across the two sales on record, with a midpoint around £65 — a reminder that these figures are wholesale saleroom results rather than dealer retail. Today in 2026 the worth of a given example depends heavily on glass clarity and shutter health, and the thin sample size means a single clean copy can shift the perceived price materially.
