Review of the Pentax Optio S4i

Pentax Optio S4i


Ultrasmall camera turns in unimpressive image quality.

The Pentax Optio S4i is relatively inexpensive and exceptionally easy to tote around, but its image quality falls short.

Pentax Optio S4i Digital Camera


The Pentax Optio S4i's attractive silver metal body measures 3.3 by 2 by 0.8 inches, and the camera weighs only 4.5 ounces, including its rechargeable lithium ion battery. Somehow Pentax has managed to find room on the back of this tiny camera to fit a...

Pentax Optio S4i


The 4-megapixel Optio S4i packs a lot of features into a tiny package, but it's not particularly speedy.

Digital Cameras - Pentax Optio S4I Digital Camera Review, Information, Specifications


When I reviewed the Optio S4 (the predecessor to the S4i) last year, I was very impressed by it. I liked its compact design, rugged case, good image quality, and excellent feature set. While it's the same camera in many ways though, I didn't find...

The Optio S4i has a 3x zoom, 5.8-17.4mm lens, the equivalent of a 35-105mm lens on a 35mm camera, just like its predecessor, the Optio S4. The lens is where Pentax made a real innovation with the Optio S-series, in that its internal elements actually...

Pentax Optio S4i


Is the S4i the king of the "micro cameras"? Find out now

Ultra-thin design still impressive in 2004 ; Quite a few controls for a point-and-shoot ; Supports underwater case ; Histograms in record and playback mode ; Impressive playback mode ; Lots of scene modes ; Cool digital filters, 3D picture mode

Photo quality -- noisy, soft, plus blurry corners too ; Manual shutter speed/aperture controls would be nice ; Movie mode not so hot in 2004 ; No AF illuminator ; Redeye ; No memory card included; paltry 10MB of built-in memory ; Flimsy door over...

The Optio S4i is a decent camera, but there are better choices out there, though they won't be as small as this.
