As I’ve mentioned before, I don’t usually like the sliding-cover design for compact cameras, but the cover on the front of the T100 is sprung and reasonably stiff, so it’s less likely than most to come open in your pocket. The cover acts as a power switch, but the camera also has a power switch on the top panel. I guess it’s there so you can use the camera as a picture viewer with the lens cover closed.
The T100 has decent performance. It starts up in a little over two seconds, which is reasonably quick for a high-spec camera, and in continuous shooting mode it can take pictures at a very brisk two frames a second and apparently keep this rate up until the card is full. The 5x optical zoom lens is not stepped, and the zoom control is proportional, meaning that it is possible to make very precise adjustments to the zoom setting. Tap the button and it moves just a little, but hold it down longer and the zoom speeds up. The optical zoom can also be used when shooting movie clips.
I particularly like the menu system, which is one of the clearest and simplest I’ve ever seen. For every selection there is an explanatory note describing the particular mode and what it can be used for, which is very helpful for inexperienced users. The T100 has three main shooting modes: full auto for speed and simplicity, a range of scene modes, and a program auto mode which has a surprisingly complete list of options, including three auto bracketing settings, several colour modes, three metering modes, a useful selection of focus modes including distance pre-sets, and adjustable flash output.
