The Yashica-Mat EM is a Japanese twin-lens reflex (TLR) camera that takes 120 roll film in the 6x6cm format. It sits within Yashica's mid-century TLR line aimed at amateurs who wanted a medium-format alternative to more expensive German twin-lens designs.

Sales data for the Yashica-Mat EM is thin: a single UK auction hammer result in January 2026 saw one sell for £60, so today's value sits in the entry-level bracket of the Yashica TLR family rather than the higher tiers occupied by the later Yashica Mat-124G. Because this is a wholesale saleroom result rather than a dealer asking price, retail examples in fully serviced condition typically command more, and condition has an outsized effect on what a body is worth given how few changes hands publicly.
