The Ansco Pix Panorama is an all-plastic, focus-free 35mm camera made in China[1]. Effectively a box camera, there are no exposure adjustments and no provision for flash.
The film gate in the camera is masked to only expose an image area approximately 13x36mm (rather than the conventional 24mm tall), typical for inexpensive 35mm panoramic cameras. This yields a "widescreen" aspect ratio of about 1:2.7 (which is greater than Cinemascope). Photofinishers were expected to enlarge this smaller negative into panoramic prints—which naturally suffer additional graininess, compared to conventional 3:2 ones.
The Pix Panorama's lens has a focal length of approximately 27mm, and in contrast to other cameras in this class its two-element design offers reasonable sharpness.
A few Pix Panorama users discovered that the film-gate mask could be snapped out, and that its lens gives good coverage over the entire standard 24x36mm frame—although the viewfinder remained cropped to the panoramic format. However the front of the camera shell can be removed by loosening four small screws, revealing that the viewfinder optics themselves are the same ones used for conventional 3:2 proportions; so if desired, the viewfinder mask can be cut away.
The bottom of the Pix Panorama cites U.S. Patent 4,595,269[2], for a double-exposure prevention mechanism. This patent dates from 1986, and is assigned to Haking in Hong Kong. It is not known whether Haking is the manufacturer of the Pix Panorama, or simply licensed this patent to another company.
