The SD450 features a 3X (35-105mm in the 35mm format) f/2.8-4.9 all-glass aspherical zoom lens. This lens features Canonís 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.
An advanced TTL AiAF 9-point autofocus system permits the camera to automatically
select the primary subject even when off-center. Focusing range is 1.0 ft. (30cm) to
infinity in normal mode and macro coverage is 1.2 to 1.6 ft. (3-50cm) in wide angle and
12 in. to 1.6 ft. (30-50cm) in telephoto.
The autofocus is light-assisted and works properly even in the
dark. The AF-assist illuminator also functions as the selftimer indicator.
The built in flash offers Auto, On, Off, Red-Eye Reduction and Slow-Synchro modes.
Flash range is 1.6 to 12 ft. (50cm-3.5m) in wide angle, 1.6 to 6.6 ft. (50cm-2.0m) in
telephoto or 1 to 1.6 ft. (30-50cm) in macro mode (with ISO set to Auto.) The focus-
assist lamp also serves as the red-eye reduction lamp.
The optional HF-DC1 external flash can be used with the SD450 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.
You can frame your pictures with the color LCD or to save precious battery power you
can use the optical eyelevel finder. This is a coupled viewfinder with approx. 82%
coverage. It has no dioptric adjustment. Next to the finder are two LEDs
that indicate the flash and focus status.
On the back is a large 2.5-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: Mode Switch with positions for Play, Record and Movie. The
Print/Share button allows you to easily print and transfer images to your computer
(Windows users only). 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 or accepts menu options and settings. The DISP
button turns the color LCD on/off and controls the amount of data displayed on it. The
MENU button calls up and dismisses the menus.
Controls on the top: the Power On/Off button, the shutter release button and
the zoom lens control around the shutter release. The zoom lens control also functions
as the magnify and index buttons in playback mode.
The AV Out handles the monaural audio and video signal which can be connected to your TV
set with the supplied cables. The high-speed USB 2.0 port for image and movie download.
The USB port can also be used for direct printing to any
PictBridge compatible photo printer.
The Powershot SD450 is equipped with a Secure Digital (SD) card slot and comes with
a 16MB SD. It can handle any capacity SD card up to 2GB.

The SD450 comes with a Canon NB-4L 3.7v 790mAh lithium rechargeable battery pack. Canon claims a fully charged battery can record 150 shots with the LCD on or 500 shots with it off and a replay time of approx. 180 minutes.
The supplied 100-240V CB-2LV 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 95 minutes.
The optional All Weather Case AW-DC50 allows you to take the SD450 underwater up to a depth of 3 meters (9.8 feet). It is also ideal for using your camera in any weather condition, at the beach or on the ski slopes.
