The Mamiya 645 Pro TL is a 6×4.5 medium format SLR, the final manual-focus body in Mamiya's modular 645 Pro line introduced in the 1990s. It was sold as a system camera with interchangeable backs, finders and Sekor C lenses, aimed at studio and wedding professionals working in the 120/220 roll-film format.

At UK auction, recent hammer prices for the 645 Pro TL body have ranged from £240 to £330, with the two logged 2025 sales sitting around a £280 midpoint. With only a small number of saleroom results to draw on, what a 645 Pro TL is worth in 2026 still depends heavily on which finder, back and lens are bundled with the body, and complete outfits sell for materially more than a bare body.
