www.butkus.us CANON DEMI S is a demi-size (24mmx18mm film frame size) camera made by Canon's world renowned precision camera manufacturing techniques. Small enough to hold in the palm of your hand, sharp lens and designed for easy handling-these are the three most outstanding features of new DEMI S. Easy-to-Handle Camera : DEMI S is of unique round shaped design to fit snugly into anyone's hand. Many parts have been specially designed to make the camera slim, easy-to-handle, and convenient for carrying around. Specially Designed Lens : Made up of 6 elements in 4 components, Gauss type 3O mm F 1.7 is fast and sharp. This lens has been specially designed for rigid aberration correction so that enlarged pictures can be obtained with the same quality as those from ordinary 35mm size film. Therefore, the extravagant lens system includes four newly developcd glasses. High Performance Shutter : High efficient shutter with speeds of Ll8-ll5OO sec., and B.View original page 5

Helicoid Focusing : Focusing is of the straight forward helicoid type where the entire lens system protrudes out. Unlike the front lens revolving type, the best performance possible can always be obtained frorn the lens with this type focusing. Extravagant Prism Viewf inder: The viewfinder, made up of four lenses and three prisms, is one of the easiest- to-see, actual upright image type viewfinders. lt is also very accurate with minimum parallax. Matching Needle Type Light Meter Goupled to Aperture: Simple and appropriate system has been adopted in order to make full use of fast lens and high performance shutter. Under this system the aperture stops can freely be set against the various shutter speeds. Other Easy-to-Manipulate Features : The zone focusing system and the easy-to-wind film advance lever greatly con- tribute to the easy-to-manipulate features of CANON DEMI S which incorporates many of the fine mechanical features found in expensive high quality cameras.View original page 6
