Youyi 友谊 SFZ

The 友谊 SFZ is a medium format (120) twin-lens reflex (TLR) camera manufactured by Youyi. Designed as an accessible entry-level or consumer-grade TLR, it utilizes the classic TLR design with a viewing lens above the taking lens, framing the image on a ground glass screen at the top. Its shutter offers basic speeds ranging from Bulb (B) for long exposures to 1/400 second, alongside an unspecified lower speed limit of 1/8". As a typical product of mid-20th-century Chinese camera manufacturing, the SFZ prioritized functionality and affordability for the amateur market, employing relatively simple construction without advanced features. Its significance lies in its representation of the era's widespread availability of medium format TLR photography to everyday photographers.
