Description — Pentax Optio E90
The Pentax Optio E90 is a compact point-and-shoot camera designed for straightforward everyday use. Its 10MP sensor with a 1/2.3-inch type produces images at up to 3648x2736 pixels, processed through Pentax's Prime image processor. The ISO range runs from 80 to 3200, and autofocus uses a contrast detection system with face detection AF and subject tracking across 3 focus points.
The 2.7-inch fixed LCD at 230,000 dots handles all composition and playback duties — there is no viewfinder. Image stabilization is digital/electronic rather than optical. The camera records video at up to 480p at 30fps.

Running on 2x AA batteries with a rated life of 220 shots (alkaline) or 620 shots (lithium), the E90 avoids proprietary battery dependency. The plastic body measures 102 x 59 x 25mm and weighs just 145g, with no weather sealing.
