The Minolta SRT-100b is a 35mm film SLR from Minolta's SRT line, a series of manual-focus cameras built around the Minolta SR (MC) bayonet lens mount. It sat in the more affordable end of the SRT range when new, aimed at users who wanted through-the-lens metering in a mechanical body.

Sales data for the SRT-100b is thin: a single UK auction hammer result from October 2024 saw a body sell for £44, which gives only an indicative figure rather than a reliable median. On that limited evidence, the SRT-100b appears to be a low-value user-grade SLR at saleroom level in 2026, and what one is worth today will hinge heavily on cosmetic condition, working meter, and whether a usable Rokkor lens is included.
