The all-glass Canon 7.1-21.3mm 3x zoom (35-105mm 35mm equivalent) boasts a maximum aperture
of f/2.8-4.9, and is constructed with 8 elements in 7 groups.
Focus range is 80cm (32.7 in.) to infinity in normal mode. Macro autofocus range is
6cm (0.2 ft.) (wide-angle) / 20cm (0.7 ft.) (telephoto) to 70cm (2.3 ft.).
The autofocus is accomplished via a three-point TTL system with user-selectable AF
points visible on the LCD monitor. The S40 also features an AF assist illuminator for
accurate focusing even in dim to dark environments.
When powered down or in sleep mode the lens is retracted back into the camera body.
The camera is powered on when you slide the front cover open.
The Manual focus option is enabled by pressing and holding the "MF" button while using
the Up or Down on the 4-way switch. The manual focus
range is 6cm (0.2 ft.) (wide-angle) / 20cm (0.7 ft.) (telephoto) to infinity.
While manually focusing, the subject area covered by the active focusing point is
digitally enlarged on the LCD to aid in critical focusing.
To save battery power or when outdoors in the bright light, switch off the LCD and frame
your shots with the eyelevel optical viewfinder. There is no diopter adjustment. The LEDs
on the side indicate recording, autofocus and flash status. The eyelevel finder shows
approximately 87% of the captured image.
The builtin 5-mode (Auto, Redeye, Slow-sync, On, Off) flash will handle most
average picture taking tasks. It has a maximum range of 13 feet (3.96m)

exposure compensation, saturation, sharpness and more.

so your subject is sharp but the background gets blurred.

night backgrounds and synchronizes
the flash to illuminate foreground subjects
