HS System (12.1 MP)HS System excels in low light allowing you to capture the real atmosphere of the moment without flash or tripod. A high performance DIGIC 4 processor and high sensitivity image sensor give superior image quality in all situations.

At ISO400 the image is marginally softer if we're looking particularly closely, but there's also no noise to report. Our test shot is also clean at ISO800 if we're losing a bit of edge detail on really close scrutiny. Some slight softening again at ISO1600, only really noticeable because the image is otherwise so clean of noise - unusually at this setting and particularly from a budget point and shoot camera.

Underneath the PowerShot ELPH 500 HS and the 300 HS, the Canon PowerShot ELPH 100 HS is the entry-level model to the 2011 ELPH lineup. The ELPH 100 HS offers a 12.1-Megapixel CMOS image sensor as well as a 3.0-inch LCD screen. The wide angle 28mm equivalent lens has a 4x optical zoom as well. Similar to the other models in the series, the HS System allows for pictures in low light situations without the use of the flash, thanks to usable ISO capabilities up to ISO 3200.The more standard Optical IS system also makes an appearance, helping to stabilise the camera's 28-112mm objective by up to three EV stops when shooting still images.

As we've come to expect with the IXUS range, there's no concession to a handgrip provided here and fingers do tend to skate around a bit on the smooth pebble-like surface. We found ourselves naturally steadying the camera in both hands, but when doing so the thumb comes to rest on the left hand side of the LCD screen smearing it with fingerprints. Despite this we were able to get surprisingly sharp results at maximum telephoto however. elements in 5 groups (1 double sided aspherical UA element and 1 single-sided aspherical UA element) All of the sample images in this Review were taken using the 10 megapixel Fine JPEG setting, which gives an average image size of around 2.5Mb.Of the following two Canon cameras: Ixus 115 and Powershot A3300, which one would you recommend? They both appear to have very similar specifications, though the Powershot has a dedicated programme mode. On the Ixus, the programme options have to be selected through the menu system. Would you say the quality of photos from the Powershot A3300 is even better than from the Ixus 115?
