Seagull 海鸥 4A-1

The Seagull 4A-1 represents a classic example of the affordable twin-lens reflex (TLR) camera design popular in China during the late 20th century. Introduced in 1980 as part of Seagull's long-running series, this medium format camera utilizes 120 film to produce square negatives on its simple yet functional chassis. Characterized by its robust, all-metal construction and bright waist-level finder, the 4A-1 provides a direct, ground-glass viewing experience through its top lens while the taking lens captures the image. Equipped with a Seikosha shutter offering speeds from Bulb (B) to 1/300 second alongside a simple focusing knob and aperture control, it offered a practical, if basic, medium format experience aimed at photographers seeking an accessible, manual alternative to 35mm cameras. Its 980g weight gives it a satisfying heft while maintaining portability for its format.
