Excerpt: Quote from the review: " Canon 's newest ELPH packs a 10x optical zoom into a compact 10-megapixel camera that also shoots full HD video . At first you'd think this is a winning combination. Let's see if those initial impressions are on the money.
Summary: However, the Canon SD4500 IS's biggest drawback is its paltry 150-shot battery life, far short of the Panasonic Lumix DMC-FZ40 (*Est. $300), which offers nearly four times the battery life for $50 less. We found professional reviews of the Canon PowerShot SD4500 IS at CNET, PC World and DigitalCameraReview.com. All three conduct in-depth testing and provide detailed write-ups along with sample photos and video analysis. Amazon.com users chime in with mixed feedback.
Pros: Wide range of auto-shooting modes, Great macro images, High-quality 1080p HD video, Fast continuous shooting
Cons: Slow startup time, Short battery life, No optical viewfinder, Lacks manual shutter and aperture settings
Summary: Starting with the lens, the IXUS 1000 HS / SD4500 IS offers a 36-360mm equivalent range. Annoyingly this lacks the 28mm or even wider coverage of rival super-zooms, not to mention their often longer total reach, but that's part of the compromise of having a slimmer body. The upside is respectable optical quality with few artefacts to worry about beyond a small amount of fringing when zoomed-out and the usual reduced contrast of a long range when zoomed-in.
Pros: Slimmer and a little lighter than most compact super-zooms., Sensible resolution means better than average low-light quality., 1080p video, slow motion at QVGA and miniature effect at 720p., Handheld Night Scene mode greatly reduces noise at high ISOs.
Cons: 10x range falls short of some rivals and lacks true wide angle., Relatively poor battery life has you recharging frequently., Best quality 4:3 mode looks small on wide display., Highly compelling rivals from the likes of Panasonic and Sony.
Conclusion: A 16:9 ratio 3.0 inch TFT screen with 230,000pixels and 100% coverage works flawlessly for HD videos; meanwhile black bands crop on either side of the screen while shooting in normal 4:3 ratio. The low resolution screen falls behind by a long shot compared to competitors and it makes you wonder why such a high-end camera was fitted with a rather basic screen.
Summary: The Canon PowerShot SD4500 is a small, solid camera that does some important things very well, but falls down in several areas. When it comes to image quality and video quality, the SD4500 is one of the best point-and-shoot cameras available, even in low light. It is also a reasonably quick camera and has a high quality lens.
Pros: Excellent image quality, Very good video, High quality stereo sound
Cons: Short battery life, Ergonomic issues, Narrow wide angle
Summary: Lacklustre scores for overall image quality, poor battery life, a lack of manual settings, and a not-very-wide-angle lens drag down our rating for the Canon PowerShot SD4500 IS. That said, it's a decent option in the realm of pocket megazoom cameras if you're looking for high speed shooting, versatile scene modes, good macro capabilities and strong performance in broad daylight.
But the price isn't right for its overall performance level.
Pros: Truly pocket-sized, 10x optical zoom lens (36-360mm equivalent), Excellent optical image stabilization, 1920 x 1080 HD video, “HS System” image quality is excellent for a point-and-shoot camera, Fun, slow motion video mode (240 FPS at 320 x 240)
Cons: 36mm wide-angle isn’t wide enough, 8.5 frames-per-second burst mode is a 2.5-megapixel scene mode, Dedicated video button is easy to accidentally press, No exposure compensation for video, No sports scene mode, The control dial on the back is a little wonky, Yucky brown color, Battery life is short when shooting a lot of video
