Polaroid's 1981 box instant camera — SX-70 film, fixed-focus 103mm f/14.6 lens, auto exposure, flash bar socket.
Polaroid's The Button was a rigid box-type instant camera released in 1981, named after its pearly white shutter button. It was one of the many low-cost non-folding cameras Polaroid built around SX-70 integral film, and was identical in specification to the original OneStep, distinguished mainly by its two-tone styling. It was even marketed as a first camera for children.
The Button takes SX-70 integral film packs, which contain the battery that powers the camera, producing 3.1x3.1-inch images. It has a fixed-focus 103mm f/14.6 plastic lens sharp from about 4ft to infinity, automatic exposure with shutter speeds from 1/200s down to 1s, a user-adjustable exposure compensation dial, a plain direct viewfinder and a socket for disposable flash bars. It weighs about 396g.
It appeals to instant-film shooters who want the vintage Polaroid look in a simple, dependable package: reviewers note it handles well and produces strong results for a box camera. Modern SX-70 film is slow at ISO 160, so it favours bright light; some users load ISO 640 600-type film and dial the exposure compensation fully dark to compensate.
Because the battery lives in the film pack, a used body cannot be power-tested empty; buyers should check the rollers are clean and free of corrosion or developer paste, the exposure dial turns, and the film door closes squarely. Flash bars are disposable and increasingly hard to find. Modern Polaroid SX-70 film is in production, so working examples remain fully usable.
