The ultra-compact Pentax Optio A40 contains a 12 megapixel sensor and 3x optical zoom, as well as 3 types of image stabilization for sharp images in any conditions (digital, electronic and movie mode image stabilization). Several scene modes, including a portrait mode with face detection, simplify decisions about image settings. Advanced users can control images more precisely using the manual exposure mode. According to reviewers, the burst mode (continuous shooting mode) outperforms many other cameras in its class, so the A40 may be a good choice for photographers who like to capture moving subjects.
