Released in 1991, the Canon Sure Shot Mega Zoom 105 was a 35mm film point-and-shoot sold in Europe as the Prima Zoom 105 and in Japan as the Autoboy Zoom 105, aimed at casual photographers wanting a zoom lens without SLR bulk.
The lens is a 35-105mm f/3.5-8 power zoom with click-stops at 35, 50, 70 and 105mm, focusing from 0.63m to infinity via a 3-point infrared autofocus system. A built-in flash rated at guide number 12-16 (ISO 100), autodate imprint, and self-timer round out the feature set, powered by a single 6V 2CR5 lithium cell.
The long zoom-to-body ratio was unusual for its class in 1991, giving reach that most contemporary compacts lacked, though the slow f/8 aperture at full telephoto demands bright light or flash. Handling favours simplicity over control, with fully automatic exposure and no manual override.
Used examples turn up cheaply among 1990s zoom compacts and remain usable on any current 35mm film. Buyers should test the zoom motor for smooth, quiet travel, check the battery compartment contacts for corrosion, and fire the flash to confirm the capacitor still charges reliably.
