Youyi 友谊 SF-1

The 友谊 SF-1 is a twin-lens reflex (TLR) camera manufactured in China by Youyi for medium format 120 film. Representing the company's entry into this popular camera type, it features a classic TLR design with a viewing lens on top and the taking lens below, connected by a common focusing mechanism. Equipped with a simple shutter offering Bulb (B) for long exposures and speeds from 1 second down to 1/300 second, it was designed as a practical tool for photographers seeking a medium format option without the complexity or cost of more advanced systems. Weighing 880 grams, it provides a solid, handheld feel typical of its class, aimed at enthusiasts and advanced amateurs rather than professionals.
