Instax (stylized as instax) is a brand of instant still cameras and instant films marketed by Fujifilm.
The first camera and accompanying film, the Instax Mini 10 and Instax Mini film, were released in 1998. The “Wide” film and first accompanying camera were released the following year. The Instax Square film and accompanying camera were released in 2017.
The formats of Instax film give an image size of 46 mm × 62 mm (1.8 in × 2.4 in) for the Mini, 99 mm × 62 mm (3.9 in × 2.4 in) for the Wide and 62 mm × 62 mm (2.4 in × 2.4 in) for the Square. The Instax colour film is available in Mini, Wide, and Square formats and the black and white Instax Monochrome is available in Mini and Wide formats.
Other manufacturers also make compatible cameras and camera backs.
Fuji’s instant film products are based upon the improvements made to Polaroid‘s SX-70 instant film system that the Eastman Kodak Company sold in the 1970s and 1980s – namely the ability to expose the film through the rear of the photograph and the reversal of the dye layers’ order so that development in the blue layer is visible first. As a result of these changes, the image does not need to be taken via a reflex mirror in order to reverse the image (as all Polaroid integral film cameras do). Colour balance and tonal range are also improved over Polaroid integral instant films. Fuji’s decision to integrate the pressure plate springs and batteries into the camera bodies rather than the disposable film pack itself helps make the Instax system more economical per exposure than Polaroid’s equivalents.
