Pentax OptioS5z Review at DigitalCameraReview
DigitalCameraReview have reviewed the Pentax OptioS5z, which has a large 2.5 inch LCD screen, 3x optical zoom lens and a 5 megapixel sensor.
“The complex lens design results in some minor but noticeable loss of sharpness at longer shooting distances and corners that are a bit soft throughout the zoom’s range. Barrel distortion (straight lines bow out from the center) is moderate and pincushion distortion (straight lines bow in toward the center) is about average. Chromatic aberration (purple fringing) is well controlled but visible in high contrast color transition areas. Optical performance was better than expected (I expected to see some vignetting and maybe even a little coma) but the zoom’s performance is actually quite good (for such a tiny and complex optic). The S5z’s Macro performance is exceptional, especially so for an ultra compact digicam.”
