Casio's Exilim series was arguably the world's first range of ultra-slim digital cameras; but until recently, their lack of bulk also meant basic features and often limited capabilities. But all that has changed with the new Exilim EX-FH100. This new model has an amazing array of features - and then some. Image resolution may not be that high, at 10.1 megapixels, but the ordinary ends there. In addition to regular shooting modes, the FH100 offers 'burst' shooting at 40 frames per second, meaning it can shoot 40 pictures in a second. The speed continues in video mode, where high-speed video capture is possible at up to 1,000 frames per second - or super-slow mode. There are also several photo-enhancing features, including 'lag correction', which captures five consecutive images so you can select the best shot in motion scenes, and a 'high-speed lighting' feature, which captures up to three exposures of a scene so the camera can assemble a final photo with the optimum exposure for different lighting conditions within a scene. There is also a 24mm-240mm 10x optical zoom lens, which supports manual focus. (With the extreme zoom, aperture is limited to F3.5-F5.7.) On the downside, all these extras make the FH100 nearly 3cm thick, far thicker than its predecessors. The Casio Exilim EX-FH100 costs HK$3,480. Pros: fast photo and video capture, 10x wide-angle zoom, HD video recording at 1280 x 720 pixels Cons: no longer that slim, limited lens aperture
