Pentax Optio A10 Review
Although a little larger and thicker than previous ultra compact Optio models (thanks no doubt to the shifting CCD mechanism), the A10 is still very compact and very slim (and the lens still collapses completely so it is flush with the front of the camera). Design-wise it's hardly breaking new ground, looking and feeling like a dozen similar models from all the major manufacturers. That said, it's very solidly built and nicely finished, and it does have an unusual 'faceted' ring surrounding the lens (I'm clutching at straws here trying to find something unusual). External controls are also pretty standard for a camera in this class; though there is a green 'function' button that offers fast access to less commonly used functions, and which is customizable.
In your hand
As is increasingly the case with ultra compact 'style' cameras the A10 sacrifices handling slightly in order to look slick and sleek. It's possible to shoot single-handed (though it doesn't feel very secure), but unless you have double-jointed fingers (or an extra thumb) it's impossible to use the zoom without supporting the 'lens side' of the camera with your other hand. That all said, most cameras of this type are the same in this respect, though the complete lack of any kind of grip on the front or back (there is a small textured area next to the play button, but it doesn't really help).
