The Pentax 10x50 6.5° XCF is a porro-prism binocular offering 10x magnification, 50mm objectives and a 6.5-degree field of view. It is a general-purpose optical accessory rather than a camera-specific item, sold under the Asahi Pentax brand.

Auction data is thin: a single UK auction hammer result from September 2025 saw a pair sell for £35, which sits at wholesale saleroom level rather than retail. On that limited evidence, the price today for a working XCF in usable condition appears to land in the low tens of pounds, with completeness of caps, strap and case likely to influence what a pair sells for.
