Features & Controls
The SD870 features a 3.8x (28-105mm in the 35mm format) f/2.8-5.8 all-glass aspherical zoom lens. This lens features Canon's exclusive Ultra High Refractive Index Aspherical technology (UA) which produces outstanding sharpness and clarity. It allows the camera body to be even thinner and more compact than previous models with smaller zoom ratios. The UA technology produces crystal clear images at all focal lengths. When powered down, the lens is retracted inside of the body and a built in shutter closes to protect the lens.
The SD870 features true Optical Image Stabilization. Unlike electronic image stabilizer systems that typically cause degradation of image quality, Canon's Lens Shift Optical IS system is based on the advancements made in the development and refinement of Canon's EF and video lenses. Reduced in size to fit ELPH scale, this Image Stabilizer provides up to three stops of camera shake correction in shutter speed equivalent.
An advanced TTL AiAF 9-point autofocus system permits the camera to automatically select the primary subject
even when off-center. Focusing range is 1.5 ft./45cm-infinity in normal mode and macro coverage is 1.2
in.-2.0 ft./3-60cm at wide angle and 1.0-2.0 ft./30-60cm at telephoto. The autofocus is light-assisted and
works properly even in the dark. The AF-assist illuminator also functions as the self-timer indicator.
The built in flash offers Auto, On, Off, Red-Eye Reduction and Slow-Synchro modes. Flash range is 1.0 - 13.1
ft./30cm - 4.0m (W), 1.0 - 6.6 ft./30cm - 2.0m (T) (when sensitivity is set to ISO Auto.) The focus-assist
lamp also serves as the red-eye reduction lamp.
The optional HF-DC1 external flash can be used with the SD870 to double the flash range
of the built-in flash.
Compact and elegantly designed, the 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.
On the back is a large 3.0-inch color LCD monitor which can be used for framing, review and changing
settings. Advanced features include "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.
Controls on the back: The Play button enters playback or review mode. The Print/Share button allows you to
easily print and transfer images to your computer (Windows users only), in record mode it acts as the Custom
button. The 4-way controller lets you navigate menus and select images during playback. In record mode you
press "Up" to change ISO sensitivity, press "Right" to change flash modes, press "Down" to change the drive
mode and press "Left" to change the focus mode. In the center is the FUNC./SET button which gives you access
to the Function menu in record mode as well as accepts menu options and settings. The MENU button calls up
and dismisses the menus. The DISP button turns the color LCD on/off and controls the amount of data displayed
Controls on the top: you can see the built-in microphone, power On/Off button as the shutter release button
with the zoom lens controls mounted around it. The zoom lens control also functions as the magnify and index
buttons in playback mode.
On the right are the IO ports. The AV Out handles the monaural audio and video signal which can be connected
to your TV set with the supplied cables. The Digital high-speed USB 2.0 port is for image and movie download.
The USB port can also be used for direct printing to any PictBridge compatible photo printer.
The Powershot SD870 is equipped with a card slot that supports use of SD or MMC cards up to
2GB or SDHC cards up to 4GB, and comes with a 32MB SD. Shown here with a speedy Kingston
Ultimate (120x) 2GB SD card - see the tables below for the approximate storage capacities.
Approximate Storage Capacities
The SD870 comes with a Canon NB-5L 3.7v 1120mAh lithium rechargeable battery pack. Canon claims a fully charged battery can record 270 shots with the LCD on and a continuous playback time of approx. 360 minutes (CIPA standard). You can also use the optional AC adapter kit ACK-DC30.
The supplied 100-240V CB-2LX 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!) The normal charging time is 90 minutes.
The optional Waterproof Case WP-DC17 (WP-DC5 shown above) allows you to take the SD870 underwater up to a depth of 40 meters (~130 feet). It is also ideal for using your camera in severe weather conditions.
