Pentax Optio S45 review
This (and the other Optio Sxx-series) cameras are some of the most fun to use.
There are many color effects filters that make picture-taking fun - even for a
jaded professional photographer. Compared to most cameras from Canon,
Nikon, Olympus and Samsung, Pentax typically has more pleasant color
reproduction in daylight scenes. The manual focus mode is well done. The
menus make sense and the AA battery power source is always welcome.
Pentax's sliding lens system in their Optio Sxx-series cameras aren't the
sharpest, especially the edges. This tends to erode their pixel advantage when
compared to competitors. (A Canon 4 megapixel comparable to Pentax 5
megapixel?) Most people won't notice this but if you're an architectural
photographer, find another camera.
Low-light autofocusing beyond a couple feet is impossible and shot-to-shot
time is a bit pokey.
