Description — Pentax Optio M90
The Pentax Optio M90 is a compact point-and-shoot camera designed for straightforward everyday photography. Its body is constructed from aluminum alloy with a soft rubber coating, measuring 99 x 59 x 23 mm and weighing just 133g — genuinely pocketable for travel and casual use. The 12MP sensor on a 1/2.3-inch chip is processed by Pentax's Prime image processor, with an ISO range of 80 to 1600.
The 2.7-inch TFT LCD at 230,000 dots provides a clear view for framing and playback. Autofocus uses contrast detection and face detection AF across 3 focus points. Burst shooting runs at 1.6fps, and digital image stabilization is on hand for steadier handheld shots.
The built-in pop-up flash covers indoor and low-light snapshots, while storage is handled by SD, SDHC, or internal storage. Video records at 30fps in 8-bit, and still image color profiles include Standard, Vivid, Sepia, and Black & White. The D-LI88 lithium-ion battery delivers approximately 200 shots per charge.
