Pentax Optio S5i Review

December 2004 | By Simon Joinson


Review based on a production Pentax Optio S5i

Announced in August 2004, the Pentax Optio S5i is an upgrade of the popular S4i with an extra million pixels, some minor styling changes and a couple of new features. The S5i is almost unfeasibly small — thanks in part to the innovative sliding lens first seen at the start of 2003 in the Optio S (and since in several Pentax and Casio models) — yet is more feature-packed than most other ultra-compacts. In an ever-growing market, and with a handful of outstanding competing models (see recent reviews of the Canon PowerShot SD300 and Panasonic DMC-FX7 for example), does the Optio S5i have what it takes to become the pocket camera of choice? Let's find out. Here's a few of the S5i's headline features to get us started:

  • 5.0 million effective pixels
  • 35-105mm equiv. sliding zoom lens
  • 1.8-inch LCD monitor
  • 21 shooting modes, including new Sports mode
  • New Pan Focus mode
  • 0.01-second shutter lag time
  • SD card-compatible and 10MB internal memory
  • Live histogram
  • 6cm Super Macro mode
  • Battery charger stand can charge two batteries at once

DPReview calibrate their monitors using Color Vision OptiCal at the (fairly well accepted) PC normal gamma 2.2, this means that on our monitors we can make out the difference between all of the (computer generated) grayscale blocks below. We recommend to make the most of this review you should be able to see the difference (at least) between X,Y and Z and ideally A,B and C.
