Kodak's 126-cartridge Instamatic — two-setting exposure, batteryless Magicube flash, UK/German built, 1971-77.
The Kodak Instamatic 155X was a viewfinder camera for 126 Kodapak film cartridges, made by Kodak Ltd in England, Kodak AG in Germany and Kodak's Brazilian subsidiary between September 1971 and 1977. It was one of the X-series Instamatics, the X denoting Magicube flash capability, and was a staple family camera of the early 1970s.
Operation is almost entirely fixed: the only adjustment is a rotating lens ring with sunny and cloudy/flash symbols, which changes the shutter speed. Flash comes from Magicubes, which fire mechanically and need no battery, mounted in a socket on the top plate, and film advances by a combined thumbwheel and lever. The drop-in 126 cartridge produces square negatives, and the camera contains no meter, battery or focusing mechanism.
Today it is chiefly a collector and display piece, and a good example of Kodak's cartridge-era design language. The all-mechanical construction means survivors usually still work, and it appeals to anyone curating 1970s family-photography nostalgia.
126 cartridge film is no longer manufactured and there is no drop-in substitute, so most examples sell for display; determined hobbyists reload old cartridges with 35mm film. Magicubes survive only as old stock and each cube gives four flashes. Check the advance wheel turns, the shutter fires and the cartridge door closes cleanly — there is little else to go wrong.
