The Topcon R is a 35mm single-lens reflex camera produced by Tokyo Kogaku, the optical manufacturer that marketed cameras under the Topcon name. It sits among the earlier Topcon SLR bodies, aimed at enthusiast and professional users when introduced.

Auction data for the Topcon R is extremely thin: a single UK auction-hammer result of £833 from 2003 is the only data point available, so today's market value cannot be reliably stated from sales evidence alone. Buyers researching what a Topcon R is worth or sells for in 2026 should treat that figure as historical and condition-dependent rather than a current guide price.
