Camera Overview — Pentax EI-100

The Pentax EI-100 is an early-era point-and-shoot digital camera built around a 1MP sensor capable of capturing images at a maximum resolution of 1280x960 pixels. Housed in a plastic body measuring 105 x 67 x 48 mm and weighing 240g, it strikes a compact and lightweight profile that made it accessible to casual shooters. The camera features a 1.8-inch TFT LCD display with 84,000 dots of resolution for image review, alongside an optical tunnel viewfinder for framing shots.

Autofocus is handled by a single-point contrast detection system, keeping operation straightforward and predictable. The ISO range runs from 100 to 400, covering typical daylight and indoor scenarios. A built-in flash supports Auto, On, Off, and Red-eye reduction modes, giving users basic control over artificial lighting.

Storage is handled via CompactFlash cards or internal storage, and the camera connects to a computer via USB. Power comes from four AA batteries, with NiMH cells recommended. Image quality modes include Normal, Fine, and Superfine compression options, offering some flexibility over file size and output quality.
