The Seagull KJ-1 is a 1970s style rangefinder camera for standard 35mm film, based on Minolta's Hi-Matic line of rangefinder cameras, noticeably taking inspiration from the Hi-Matic 7s II. It has a an reverse Galilean bright-frame viewfinder with parallax marks and coupled rangefinder.

Three control rings are around the lens barrel: a distance setting ring for distances from 1m to infinity, a speed setting ring for speeds 1 sec. to 1/300 sec. plus B mode, and an aperture setting ring for apertures from f2.8 to f16. All settings have to be selected manually. This camera does not have a built-in lightmeter. The camera has a film advance lever and a hot shoe. The lens is a Seagull Haiou-45 1:2.8 f=38mm.
