Neocamera detailed review
Discontinued: No longer produced by the manufacturer. May still be in stock or found used.Digital Camera Description
The Pentax Optio S55 is a Compact Digital Camera with a 1/2.3" sensor. Its 5 Megapixels CCD sensor offers an ISO 50-400 sensitivity range which is expandable to ISO 50-400. With 5 MP of resolution, sharp prints are possible up to 11" x 8" at 240 DPI.
This camera features a mechanic shutter that can expose for 1/2000 to 4s. With a fastest shutter-speed of 1/2000, fast action can easily be frozen. Given that is does not support very slow shutter-speeds, this camera is unsuitable for night photography.
The Pentax Optio S55 features a Contrast-Detect AF system. Manual Focus is also available.
This camera does not feature any seals to protect it against adverse weather, dust and moisture. Care must be taken, just like with most electronics. There is no viewfinder on the Pentax Optio S55 and no provision to add one.
