Despite their small size the IXUS cameras usually have a pretty comprehensive specification and a number of models sport a touchscreen interface for a more intuitive control.
It's not an exhaustive product line, but there are crucial feature differences between one IXUS camera and the next. Here's our take on the best Canon IXUS models…
Canon IXUS 125 HS / Canon PowerShot ELPH 110 HS
Specs: 16.1MP, 3-inch 461,00-dot LCD, 5x zoom (24-120mm equivalent)
Though it's an entry-level model, the pocket-sized IXUS 125 HS has a respectable specification that includes the same DIGIC 5 processor as Canon's recent SLRs and compact cameras higher up the line.
In addition, the sensor is a 16.1MP back-illuminated CMOS device that produces decent results in a range of conditions, even when the highest sensitivity setting (ISO 3200) is used.
With a focal length equivalence of 24-120mm, the lens is also versatile. Novices will particularly appreciate the Smart Auto mode that automatically selects the best camera settings from a selection of 58 presets, which should cover most situations.

Specs: 16.1MP, Wi-Fi-enabled, 3.2-inch touchscreen, 5x zoom (24-120mm equivalent)

Canon IXUS 500 HS / Canon PowerShot ELPH 520 HS
Specs: 10.1MP, 3.2-inch LCD, 12x zoom (28-336mm equivalent)
Canon's IXUS 500 HS has the same rectangular styling, pixel count and zoom range as the Canon IXUS 510, but without the touchscreen functionality or Wi-Fi connectivity, making it more attractive to 'old school' photographers looking for a point-and-shoot camera to slip in a pocket.
This solid feeling camera has small buttons, so it may not suit those with big, sausage-like fingers, but the controls are easy to get to grips with and using the camera is plain-sailing.
Thanks to the DIGIC 5 processing engine the IXUS 500 HS also starts up quickly and produces decent results in double-quick time.

Canon IXUS 510 HS / Canon PowerShot ELPH 530 HS
Specs: 10.1MP, Wi-Fi-enabled, 3.2-inch touchscreen, 12x zoom (28-336mm equivalent)
The back of the IXUS 510 HS is almost completely filled by the 3.2-inch 461,000-dot touch-sensitive LCD screen. Built-in Wi-Fi technology allows quick and easy image sharing to another camera, a mobile phone, a computer or Facebook.
Sensitivity can be set to up to ISO 3200 in Program mode, though the best results are obtained by keeping to ISO 800 or below.
All things considered the IXUS 510 HS is a decent solution for the casual photographer who wants a small camera that takes better images than there cameraphone and allows them to be shared directly.
