There are numerous improvements including a subtle finger grip on the front of the camera, the new quick reset button on the rear and most noticeably the larger 1.8" TFT LCD monitor. The Optio S4i remains one of the smallest and lightest ultra-compact's.
The Optio S4i The convenient digital compact with performance way beyond its dimensions.
Without a doubt, the first thing youll notice about the Optio S4i is its incredibly compact dimensions that make it even easier to carry than a modern mobile phone! Take a few shots with it, however, and youll start to notice so much more. Embracing PENTAX ingenuity, all controls have been placed within easy reach from the ready-to-shoot position. Enabling simpler composition, focusing, and viewing, its equipped with an advanced 1.8-inch TFT LCD monitor that offers a 100% field of view. It even delivers truly satisfying clarity with the power of 4.0 effective megapixels and extends real compositional freedom through 3X optical zoom, which combines with 4X digital zoom for total zoom capacity of an incredible 12X. A camera that makes digital photography more enjoyable, more simple, yet more refined, the Optio S4i from PENTAX delivers sophistication beyond its dimensions.
Ultra-compact, refined design
With a newly developed multi-chip module system and an innovative sliding lens that retracts to be flush with the body of the camera, the Optio S4i achieves exceptionally compact dimensions of just 83 (W) x 52 (H) x 20.5 (D) mm. It also has a body of attractive aluminum alloy that offers a sense of sophistication and is built with bold, straight lines that serve to communicate sheer, expressive functionality.
Easily worn about the neck or slipped in the pocket, its the elegant choice in compact digital cameras for sophisticated shots at any time.
High-quality smcPENTAXlens offering 3X zoom
The Optio S4i features a lens from the smc PENTAX series a lineup renowned throughout the world for sheer imaging excellence. With 3X zoom with a focal range covering angles of view equivalent to those of a 35-105mm lens in 35mm format, it delivers the freedom to zoom out for shots of scenic beauty and move in for telephoto shots that offer flatter, kinder perspective. All 5 groups of 6 elements are crafted entirely from glass, with two lenses crafted to be aspherical on each side, and optical zoom can also be augmented with 4X digital zoom, which takes the cameras total zoom capability to an impressive 12X.
4.0 effective megapixel clarity
For superior clarity that extends from macro shooting to the capture of expansive landscapes, the Optio S4i is equipped with the power of 4.0 effective megapixels. It also employs the benefits of a primary color filter and advanced imaging technologies, which together bring out brighter, more natural colors and achieve a significant enhancement in general image quality.
Exceptional user-friendly operability is achieved largely through use of newly designed processing circuitry and an innovative software algorithm elements which work hand in hand to take responsiveness to a new level and support a shutter time release lag of a mere 0.01 seconds*.
