Canon 518 SV is fully automatic Super 8 film camera that allows you to focus on capturing the moment. It features a sharp and fast F1.8 5x zoom lens with zooming range of 9.5-47.5mm, that can be extended to 6.2-31mm with a wide-converter or 15.6-78mm with a tele-converter. The single-lens reflex viewing and microprism screen rangefinder ensure accurate focusing. The automatic through-the-lens exposure control uses a CdS photocell with servo EE meter for precise exposure. The camera is powered by 4 penlight batteries that drive the film and power the zoom and electric eye, so you don't have to worry about missing a shot due to dead batteries.
