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.
Excerpt: The Canon PowerShot SX40 HS ($429) is a super zoom camera with one of the most powerful lenses on the market. This 35X zoom lens has an incredible focal range of 24 - 840 mm, which should cover every possible shooting situation that you'll run into.
Conclusion: For those looking to get started with photography, this is a fantastic, fuss-free choice that will help you learn more about manual controls and different shooting options. It's worth noting that while you can pick up an entry level DSLR, such as the Canon EOS 1100D for around the same price, which will give better image quality overall, you do get the incredible zoom range in a smaller and lighter body that isn't part of a more expensive system.
Summary: But although its images look great for an ultra-zoom, they can't match a real DSLR's. "If image quality tops your list of priorities, then you should probably be on the lookout for a budget DSLR and forget all about the ear candy of this camera's fabulous 35x optical zoom," Williams says. For example, the SX40 HS can't shoot RAW (uncompressed) images like DSLRs (and some rival ultra-zooms) can.
Pros: Versatile lens range, Excellent CMOS image sensor, Shoots full 1080p HD video, Optical image stabilization, Lots of manual control, Improved shooting speed
Cons: No RAW mode, Relatively small (2.7-inch) LCD screen
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
Excerpt: Built to replace the SX30 IS , Canon has announced the new PowerShot SX40 HS. While the previous model had more megapixels (14 to be exact), the new SX40 HS has a better CMOS sensor (12-megapixels). This sensor, when combined with the upgraded DIGIC 5 image processor, means this new model can take better pictures at higher speeds.
Summary: On the surface the SX40 HS is almost indistinguishable from its SX30 predecessor, and much the same can be said about using the camera. It's disappointing to not see significant advances in focusing speed and performance, and while a speedier 10.3fps Scene mode is available it's still not class leading in speed or ability. The small and low resolution LCD screen also feels out of date compared to the competition and there's still no sign of Raw shooting.
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.
