Konica's colourful 1982 fixed-focus 35mm compact — 36mm f/4 lens, manual wind, sold in Japan as the C35 EFJ.
The Konica Pop was a fixed-focus 35mm compact introduced in 1982, sold in Japan as the C35 EFJ. Offered in a spread of bright colours as well as black, it became one of the defining cheap-and-cheerful compacts of the 1980s, selling around 1.5 million units before refreshed versions, including a metallic silver model, arrived in 1985.
It uses a 36mm f/4 fixed-focus lens with a mechanical shutter fixed at 1/125s. Film advance is manual by lever and rewind is by crank, so no motor is involved. A CdS cell drives an underexposure warning LED in the viewfinder, and film speed is set manually via a selector for ISO 100, 200 and 400. The built-in flash has a close-up setting that adjusts the aperture for near subjects, and there is a tripod bush. The body measures roughly 116x70x47mm and weighs about 270g.
The Pop suits beginners, students and anyone after a simple, characterful street and party camera. The f/4 lens and single shutter speed limit it to daylight or flash range, and results have the slightly soft, punchy look that has made it popular with lomography-style shooters. The coloured versions carry a collectability premium over black.
Because the shutter is mechanical and wind-on is manual, a Pop will usually fire with no battery at all; batteries are only needed for the flash and the low-light LED. That makes flash function the main electrical check: confirm it charges and fires, inspect the battery compartment for corrosion, verify the ISO selector clicks through its three positions, and check the film door and rewind mechanics.
