Ultra-compact camera featuring the company's new 'HS' system that promises better low-light performance and high-speed photography through a combination of a 10MP back-illuminated CMOS sensor and DIGIC 4 processor. It sports a 28-105mm equivalent f/2.0-5.3 stabilized zoom lens (offering the same range as the S90 but for a smaller sensor), 3 inch LCD and P/A/S/M shooting modes. The camera also features a Super Slow Motion movie mode that records 340x240 movies at 240fps, as well as 720p HD movies capture. It's not Earth-shattering but, if you want a point-and-shoot (with entirely optional user control), the SD4000 IS pretty much peerless.
