Pentax Optio S Review
Pentax announced the ultra-compact (in the most accurate sense of the phrase) Optio S at CES 2003 in January 2003. The Optio S measures just 83 x 52 x 20 mm (3.3 x 2.0 x 0.8 in) and weighs in at just 115 g (4.1 oz) ready to shoot, specifications we'd expect to see from an ultra-compact fixed lens digital camera, all the more amazing then that it has a three times optical zoom lens. Pentax has achieved this feat of miniaturization by altering the lens design so that when retracted three of the lens elements actually move upwards allowing the lens to take up less space. The only hint of this design from the outside is the vertically offset front lens element. The Optio S has a three megapixel sensor, lightweight Lithium-Ion rechargeable battery and stores images on SD / MMC cards.

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.
