The Canon AiAF autofocus system is also very quick, focusing in good light in about 1/5th of a second. It is a little slower in low light, but thanks to the AF illuminator it can focus in complete darkness. In practical tests, the illuminator beam had an effective range of at least four metres.
This is probably also a good time to mention the IXUS 750’s fantastic built-in flash. In the camera’s specification sheet its stated range is five metres, but in actual use I found it to be closer to eight or nine metres. It really is astonishingly powerful, easily bright enough to illuminate a large room. It does produce quite ferocious red-eye though, as well as cries of “Argh! I’m BLIND!” from anyone looking your way when you fire the thing off. Cruel, but amusing.
Although it is first and foremost a snapshot camera, the IXUS 750 does have some useful features. The main mode dial offers three main shooting modes, auto, manual and scene mode, each of which provides differing levels of user control. In each mode, settings can be adjusted quickly and easily by pressing the function button, which activates an easy-to-use on-screen menu of frequently used options selected via the D-pad. In manual mode this gives access to exposure compensation, white balance setting, image effects, metering mode, compression quality and image size.
In the nine different pre-programmed scene modes only exposure compensation, compression and image size are controllable, while in full auto mode even exposure compensation is disabled, leaving only compression quality and image size under the user’s control. Full auto mode also disables some of the functions in the main menu, but in manual mode the full range is available, including two and 10 second self timer, composition grid lines, and digital zoom. Kudos to Canon for having the default setting on the digital zoom as ‘off’.
Other frequently used options are accessed by secondary functions of the D-pad, including ISO setting, macro mode, drive mode, self-timer and flash mode, although some of these are unavailable of limited in full auto mode.
