The A520 features a 4X (35-140mm in the 35mm format) f/2.6-5.5 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 9-point autofocus system permits the camera to automatically select the primary subject even when off-center. The focusing range is:

• Normal AF - 1.5 ft. (45cm) to infinity
• Macro - 2.0 in. (5cm) to 1.5 ft. (45cm) in wide angle and 11.8 in. (30cm) to 1.5 ft. (45cm) in telephoto.
• Manual - 2.0 in. (5cm) to infinity in wide angle and 11.8 in. (30cm) to infinity in telephoto.

In low light conditions the focus-assist lamp helps to illuminate the subject for accurate focusing.
