Features & Controls

The SD940 IS features a 4x (28(w) - 112(t) mm in the 35mm format) f/2.8-5.9 all-glass aspherical zoom lens. When powered down, the lens is retracted inside of the body and a built in shutter closes to protect the lens.

With Canon's Optical Image Stabilization technology (OIS), users have the flexibility of actually shooting at shutter speeds 2-3 stops lower than would otherwise be possible.

An advanced TTL autofocus system permits the camera to automatically select the primary subject even when off-center. Focusing range is 1.0 ft. (30cm) to infinity in normal mode and macro coverage is 1.2 in.- 1.6 ft./3-50cm (W), 1.0 - 1.6 ft./30-50cm (T). There's also a digital macro mode that covers 1.2-3.9in./3-10cm (W). The autofocus is light-assisted and works properly even in the dark.


The built-in flash offers Auto, Red-eye Reduction, Auto Red-eye Correction, Flash On, Flash Off (FE lock, Slow Synchro). Flash range is 1-13ft./30cm - 4.0m (Wide angle), 1.6 - 6.6 ft./50cm - 2.0m (Telephoto) when sensitivity is set to ISO Auto. The focus-assist lamp also serves as the red-eye reduction lamp.


On the back is a large 2.7-inch 'PureColor LCD II' monitor which can be used for framing, review and changing settings. Advanced features include new multi-level coating that reduces glare, and resists scratches, smudges and fingerprints as well as a 'Quick-bright' function which switches the brightness to the highest setting by pressing the DISP button for 1 second. When shooting in dark lighting, the LCD is automatically brightened to make it easier to frame and focus on the subject.

Pressing this button while the camera is off will enter the playback system. Next is the Mode Switch with positions for Auto, Camera and Movie. Next is the 4-way controller.

In the center is the FUNC./SET button, which accepts menu selections as well as gives you access to the Function shortcut menu.

The SD940 IS comes with a Canon NB-4L 3.7v 760mAh lithium rechargeable battery pack. Canon claims the NB-4L can power the SD9400 for up to 220 still images or 360 min. of continuous playback on a single charge (using CIPA Standard testing.) The supplied rapid charger plugs directly in the wall socket and charges the battery out of the camera which is very handy if you have a second battery (highly recommended!)
