Features & Controls



Canon Powershot A70

The A70 features a 3X (35-105mm in the 35mm format) f/2.8-4.8 all-glass aspherical zoom lens. When the camera is powered down the lens is retracted inside of the body and a built in shutter closes to completely protect the lens.

An advanced TTL AiAF five-point autofocus system permits the camera to automatically select the primary subject even when off-center. Focusing range is 1.5 feet to infinity in normal mode and macro coverage is 2 to 18 inches in wide angle and 10 to 18 inches in telephoto. In low light conditions the focus-assist lamp (see above) helps to illuminate the subject for accurate focusing.
