Conclusion: The Canon PowerShot SX40 HS offers an impressive 35x zoom range, fast continuous shooting, and very good image quality. You won't be able to fit it into your pocket, but this megazoom can capture telephoto images that a smaller camera couldn't dream of.
Canon PowerShot SX40 HS Review: A Formidable Ultrazoom
Digital Camera Review
16 November 2011
Summary: I loved the promise of the SX40 - a single, integrated, relatively inexpensive camera that can capture every image from wide-angle to telephoto, from landscapes to sports - but quirky auto-focus at the telephoto end and the difficulty of finding subjects when zoomed in make it less than great for any type of wildlife or distance sports photography. And the penalty for the huge zoom range is a bulky lens which makes it difficult to fit in your pocket.
Pros: 35x optical zoom, Impressive Image Stabilization, Full complement of features
Cons: Quirky auto focus, No RAW Mode, Bulky for a point and shoot, Small sensor compared to non-ultrazooms in its price range
Summary: Sure Nikon and Olympus now have models boasting 36x zooms, but the difference between them and the 35x zoom of the SX40 HS is negligible. As such it's fair to say they all share the broadest and longest ranges around. You can't help but be impressed when you zoom from one end of the range to the other.
There is however one other camera which shares this powerful range: Canon's earlier PowerShot SX30 IS.
Pros: Enormous 35x zoom lens. Can zoom while filming., 1080/24p video and choice of two slow motion modes., Fully articulated screen and flash hotshoe., Fast continuous shooting option.
Cons: Relatively small and coarse screen compared to rivals., Buffer at 10.3fps only lasts for about one second of action., No built-in GPS, no RAW, can't assemble its own panoramas., Continuous AF sometimes struggled a little during video.
Conclusion: Your decision to buy the Canon Powershot SX40 HS is likely to be based on whether or not you prefer the simplicity and lower price of a digital camera with a fixed lens or whether you prefer the ultimate flexibility of a Digital SLR. If you prefer a camera where one lens covers just about all photo opportunities then the Powershot SX40 HS is hard to beat. There are no real issues with picture quality and it has a set of features that few other models can match.
Pros: Picture quality, features, manual controls, movie features, vari angle LCD screen, handling
