The Pentax Optio T20 is a 7.3-mega pixel camera with 3x optical zoom and 4 digital zoom. The T20 comes with a large 3-inch LCD screen. Trusted Reviews has reviewed the Pentax Optio T20 and they write: “Like its siblings it features Pentax’s 6.2-18.6mm (37.5mm-112.5mm equiv.) Sliding Lens System, which folds down flush with the camera’s body.

This allows the T20 to be just 19.5mm thick, making it one of the slimmest cameras available. It has a very sleek and minimalist appearance, with a simple rectangular shape rounded off on the top and bottom edges. The body is all aluminium alloy which feels nice and sturdy, and build quality is of a very high standard. Weighing 135g it is nice and light and won’t make much of a bulge in your shirt pocket.

Because of its touch-screen control system there are only two buttons on the back panel, so despite the large monitor there is plenty of room to grip the camera, with a large textured thumb grip area on the back.”

“The Pentax Optio T20 could have been a much better camera. It is stylish, well made and the touch-screen technology is well implemented and has some genuinely useful features. However very slow performance, severely limited battery duration and the annoying AF monitor-freeze are major handicaps that are impossible to ignore.”
