The new Pentax Optio A20 boasts 10 megapixels, no less than three anti-shake functions and Face Recognition AF & AE for portrait work. The Optio A20 offers a versatile manual shooting mode. Add to this, a 232,000 pixel 2.5 inch LCD and Movie mode MPEG-4 DivX (640 x 480) capture at 30fps and guaranteed video playback on all DivX certified devices.

DPReview has done a full review of the A20 and tells us whether this update is better than last years disappointing A10.

"So does the A20 deliver the necessary improvements? The sad answer is not nearly enough. Instead of taking the good stuff (the image quality) and concentrating on what was really wrong with the A10 (the performance) Pentax decided what it really needed was more pixels. This is like putting wide rims and low profile tires on a car that stalls every five miles. It doesn’t fix the real problem but ’hey, look! big wheels!’
…
Of course to be fair Pentax has made some improvements; the focus and shutter lag are better than the A10, high ISO performance is a little better and that awful zoom mechanism sorted.."

It’s not a poor camera all in all, it’s just not best of breed.
