Pentax has a couple of new digital camera upgrades to announce today. The Optio E40 is an entry-level model with 8.1MP, 3x zoom (37.5 - 112.5 equiv) and clearly geared toward ease-of-use. Face Recognition is here along with Auto Picture mode, Digital Shake Reduction (increases ISO to achieve higher shutter speeds) and Pentax's fully-automatic 'Green Mode'. The Optio M40 meanwhile piles on the style with a slim alloy body measuring a mere 18mm (0.7") deep and is available in a variety of colors.
