Features & Controls
The A720IS features a 6X (35-210mm 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 9-point autofocus system permits the camera to automatically select the primary subject even when off-center. The focusing range is:
In low light conditions the focus-assist lamp
helps to illuminate the subject for accurate focusing.
The built in flash offers Auto, On, Off, Red-Eye Reduction On or Auto. Flash range is 1.0 ft. (30cm) - 11ft. (3.5m) in wide angle, 1.8 ft. (55cm) - 8.2 ft. (2.5m) in telephoto mode.
This is a Light-guide zoom flash that changes its angle according to the lens' focal length. The AF-
assist lamp also serves as a red-eye reduction lamp.
Compact and elegantly designed, the optional High-Power Flash HF-DC1 complements your
PowerShot perfectly and requires no accessory shoe. With a strong light output (guide
number 59 ft.) and wide angular field (28mm), it delivers proper illumination up to
approximately 30 feet and in all zoom positions. The flash fires in synchronization with
the main flash, and output is adjusted accurately and automatically. A "Manual" mode
prevents others from firing your flash.
You can frame your pictures with the color LCD or to save precious battery power you can use the optical finder, a rarity among digicams these days.
This is a zoom coupled viewfinder with approx. 80% to 85% coverage. It has no dioptric adjustment. Next to
the finder are two LEDs that indicate the flash and focus status.
On the top you'll find the On/Off button, the shutter release with the zoom lens control mounted around it. In playback mode the zoom lever functions as the index and magnified image control.
