Canon PowerShot SD800 IS


The SD800 IS (IXUS 850 IS), announced just before Photokina 2006 back in September, is a sister model to the popular SD 700 IS (IXUS 800 IS), one of the better ultra compact models launched last year. As well as an extra million pixels or so, the new...

Good resolution, good color, Useful and fairly rare 28-105mm zoom range, Clean, detailed results at lower ISO settings, Reliable exposure system, Fast and accurate focus, Very responsive, Excellent user interface, easy to use, Face detection AF/AE (it...

AiAF focus a bit unpredictable - turn it off, Very little manual control, ISO 200 and 400 suffer from the effect of noise reduction and loss of low contrast detail, ISO 800 and 1600 of limited use, Finish very susceptible to marks and scratches, Still...

The SD 700 IS was perhaps my favorite point and shoot camera of last year, ticking all the right boxes (small, stylish, reliable, good output, easy to use) and showing that, for all the grumbling about Canon's dominance of this market, when they get...

Wee Willy Like the Image Capture


This 7.1-megapixel camera has all the standard extras, like face recognition and autofocus, plus exceptional image stabilization. Dig deep into the exhaustive

Shots look great: Color is reasonably on target and images are crisp even with significant shake. Wide-angle 3.8x zoom lens captures a big picture. A real hacker's cam, with dozens of surprise features and settings. Spare battery included. Shutter lag...

Zoom controls difficult to reach. Comparably weak flash. Some odd screen modes that will go largely unused: How often will you need an aquarium setting

The 10.0 megapixel PowerShot SD900 and the 7.1 megapixel PowerShot SD800 IS Digital ELPHs take the marriage of style and substance to a new level, by offering an array of user-friendly features along with faster response time and a new face detection...

Canon PowerShot SD800 IS First Impressions Review


Debuting as the Canon IXUS 850 IS in Europe and the Canon PowerShot SD800 IS, the 7.1-megapixel digital camera comes with a host of new technologies. The new Digic III processor in the camera recognizes, tracks, and focuses on faces. Other components...

- Steady image stabilization - Effective, quick face recognition - Great movie mode - Interesting My Colors modes - Extensive ISO 80-1600 options - Lengthy burst mode

- Awkward handling - Relatively slow 1.7 fps burst mode - Limited max f/5.8 aperture in telephoto - Below average 270-shot battery - Off-center placement of flash

Canon PowerShot SD800 IS


The 7-megapixel camera's tiny body is shiny, curvy, and very attractive. But it may be just a bit too stylish for its own good. For instance, the power button is a tiny, illuminated half-oval built flush into the top panel; without actually pressing...

Good focal range for lens; quick performance; optical image stabilization; attractive design.

Few manual controls; extremely noisy photos at ISO 1,600.

A slim, stylish body, a wide-angle lens, very good photo quality, and snappy performance make the Canon PowerShot SD800 IS a great point-and-shoot.

Canon PowerShot SD800 IS Digital ELPH Digital Camera - Full Review


If you're tired of red-eye and relying on flash, the Canon SD800 IS digital camera is your prayer answered. The Canon SD800's built-in image stabilization combined with the high ISO sensitivity extends available light, non-flash photography into the...

You can't beat image stabilization, Face recognition really works

A little bulky compared to its competitors

Canon PowerShot SD800 IS Digital ELPH


That all sounds pretty nice to me. Other features on the SD800 include optical image stabilization, a 2.5" LCD display, point-and-shoot operation, and a VGA movie mode -- all in a compact and very stylish metal body

Very good photo quality, low noise through ISO 400 (but see issues below) ; Wide-angle lens ; Optical image stabilization ; Compact, super stylish metal body ; Large, sharp 2.5" LCD display; easy to see in low light ; Has an optical viewfinder (a...

Some corner softness and purple fringing ; Redeye a big problem ; Current zoom setting not shown on LCD; lens needs more "steps" as well ; More manual controls would be nice ; No live histogram in record mode ; Date/time printing only at 1600 x 1200...

Canon bundles a 16MB memory card with the SD800, which holds just four photos at the highest quality setting. That means that you'll need to get your hands on a larger memory card right away. The SD800 can use Secure Digital (SD) and MultiMedia (MMC)...

Canon Powershot SD800-IS


After shooting with my Rebel XT exclusively for almost a year, I decided that having a point and shoot again would be a good idea as I was trashing my Rebel by carrying it around everyday. After a few recommendations (not the least of which was...

Small pocketable size ; Excellent color reproduction ; Optical image stabilization ; Video can be shot at 640 x 480

Average low-light performance ; Images are noisy at ISOs higher than 400 ; Autofocus is a bit slow at times ; Zooming in video is digital instead of optical ; No manual control of aperture or shutter ; A bit chunky compared to other compact cameras

I'm only writing this part in the interest of getting the story out there, but I really can't say with any degree of certainty whether or not the included software is worth a damn. I'm a Mac user and when it comes to photo management, I use iPhoto. For...

Product Specifications

Canon Digital IXUS 850 IS imaging processor DIGIC III achieved high-definition and higher-speed processing without damaging the beauty of subjects. Real-image Zoom viewfinder can be used to conserve power by turning the LCD monitor off while shooting. Use the LCD monitor to compose close-ups in macro mode since images composed with the viewfinder may be off-center. This camera is equipped with a 3.8x optical zoom lens with a focal length of 4.6 - 17.3 mm (35 mm film equivalent 28 - 105 mm), f/2.8 - f/5.8, which is ideal for a wide range of photography including snapshots and scenic shots. The LCD monitor can be used to check an image during shooting, to play back recorded images or to adjust menu settings. You can have the camera automatically detect the position of a face and use this data to set the focus and exposure while shooting. Exposure Compensation can be adjusted in 1/3 stops in the range -2 to +2. Adjust the exposure compensation to a positive value to avoid making the subject too dark when it is backlit or shot against a bright background. Adjust the exposure compensation to a negative value to avoid making the subject too bright in night shots or when shot against a dark background. Shoot with auto, high ISO Auto, ISO 80, ISO 100, ISO 200, ISO 400, ISO 800 and ISO 1600 equivalent. Raise the ISO speed to use a fast shutter speed when you wish to reduce the effects of camera shake or avoid blurry subjects, or to turn the flash off when shooting in a dark area. Normally, the Auto white balance setting selects an optimal white balance. When the Auto setting cannot produce natural looking colors, change the white balance using a setting appropriate for the light source. Start playback with the image that was last displayed during the last playback session (Resume Playback). However, this image is reset when new images have been shot, when a memory card has been edited on a computer or when another memory card has been inserted, in which case playback starts with the image shot last. The histogram is a graph that allows you to check the brightness of the image. The greater the bias toward the right, the brighter the image. If the image is too dark, adjust the exposure compensation to a positive value. Similarly, adjust the exposure compensation to a negative value if the image is too bright.
