The Suntone MM350 is a basic camera for 35mm film. It is nearly identical to the Ansco Pix Panorama, Halina Panorama, Revue Panorama, Arico Panorama CL-168 and Hanimex Panorama 35. It has a fixed-focus lens, a single aperture and a single shutter speed. It is not a proper panoramic camera, rather it simply exposes only the middle part of the negative. It operates without the need for batteries.
The name of the camera is not on the camera itself, but appears on the box. Strangely, the box spells the company name as Sun Tone, while the usual spelling was Suntone.
