There is a fairly modest 5x optical zoom available, with 4x digital zoom on top - but we found this made images very fuzzy indeed. Normally, we would suggest turning off digital zoom, but there is no option to do this on the H10. At least zooming stops when it reaches the extent of optical power, so you can choose not to use digital zooming in each instance.
The majority of settings are accessed via the central button on the back. But ranged around this are specific controls for changing the shooting resolution, toggling through the flash modes, turning the self-timer off and on, and enabling the Intelligent Lighting setting.
Returning to the central button, this calls up the Options menu, which converts the four buttons into navigational controls. Within this menu, you can enable macro mode, which allows focusing up to 1cm away. There are seven exposure settings, ranging between + and -1EV, but no manual shutter configuration. You can also vary between nine levels of sharpness. White balance options include presets for daylight, fluorescent and tungsten, alongside fully automatic, but there is no manual setting. A night mode is also available.
A few more options are included in the photo menu. Strangely, backlight compensation is only available for still images, not video. You can also choose a 5-picture continuous shooting mode, and ‘Two in One', which combines two shots into one single image, although we're not entirely sure why you would want to do that in camera.
In either mode, there are three digital effects available, including black and white, classic, and negative. There is also a Motion Detect setting. Turn this on, and the camera will record video when it detects motion, although the external power supply will be required to use this for any length of time.
In general, we found the H10 reasonably comfortable to shoot with. However, the placement of the record button to one side initially means you are likely to press the Options button instead, as that is where your thumb more naturally sits.
