Seagull 海鸥 DF-AB

The Seagull DF-AB is a Chinese-built 35mm SLR camera featuring the universal M42 lens mount. Produced during the late 20th century when Seagull was actively manufacturing affordable cameras for domestic and international markets, the DF-AB represents the company's approach to providing basic photographic equipment at accessible price points. With its B (bulb) and 1"-1/60" shutter speeds, it was designed for amateur photographers seeking straightforward functionality without advanced exposure control or sophisticated mechanics.
