Seagull 海鸥 4A-107 （建厂40周年纪念）

The Seagull 4A-107 (建厂40周年纪念) is a twin-lens reflex (TLR) camera introduced in 1998 by Seagull to commemorate the 40th anniversary of their factory. It utilizes 120 roll film, producing 6x6cm square exposures. As part of Seagull's established 4A series, it maintains the brand's characteristic practical design, featuring a coupled rangefinder for focusing and a simple shutter with speeds from Bulb (B) for long exposures to 1/300 second. Its primary significance lies in its status as a commemorative item within Seagull's lineup during a period when affordable medium format cameras were still relevant to Chinese photographers, offering a straightforward mechanical experience without the complex features of more advanced models. It represents a continuation of Seagull's tradition of producing accessible TLR cameras rather than a groundbreaking innovation.
