The focus and exposure time are fixed. The aperture can be selected depending on the lighting conditions. There is also a built-in flash that is powered by two AAA batteries but does not work with this unit.
Images with the I-Zone are the same size as a 35mm negative, 24 x 36mm. The film is an integral film, but there is no battery in the film cartridge. This requires the film to be pulled out of the camera after shooting, similar to the old Polaroid pack film cameras.
Unfortunately, instant film is no longer made for this format or camera. Still available in expired film.
