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.
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.
Excerpt: The Canon SX40 HS is a compact bridge camera with an extreme zoom lens. It offers focal length settings between 24mm and 840mm (35mm film camera equivalent), which allows users to shoot nice wide-angle shots to extreme telephoto images.
Excerpt: PowerShot are the larger of two small Digital Camera ranges offered by Canon. This unit is larger than most and on first glance could be mistaken for a DSLR unit. The main difference is that its lens is not interchangeable.
Excerpt: The Powershot SX40 HS is Canon's latest release into the superzoom market, replacing the previous SX30 model. Still retaining most of the key design features from its predecessor, the SX40 builds on the original blueprint with the inclusion of Canon's new DIGIC 5 image processor, which enables...
Summary: Since the SX40 HS costs roughly the same as an entry level DSLR plus kit lens you've really got to want the broad paparazzi-style focal range on offer here to even think about parting with your cash.
Conclusion: The Canon PowerShot SX40 HS may not differ a great deal from its SX30 predecessor, but it’s still a mighty fine superzoom. Image and movie quality are both decent, the 35x optical zoom has a huge range that few other models can challenge and the optical image stabilisation system is also top notch.
Pros: Decent image quality, mega zoom, optical image stabilisation, hotshoe for external flash
Cons: Not very different to SX30, 2.7in screen is small and low resolution, viewfinder is like a TV at the end of a tunnel
