Ephotozine have reviewed the Ricoh Caplio R4.
The Ricoh R4 is very compact 6 megapixel digital camera that offers an amazing 7.1 times optical zoom (focal length of 28-200mm, 35mm equivalent), a large 2.5 inch LCD display, optical vibration reduction and a 1cm macro mode.

The review results:
“I really enjoyed using the Ricoh Caplio R4, having a long zoom range like this in such a tiny camera is a lot of fun, especially as it is equivalent to 28mm at the wide end. The price you pay is in the maximum aperture of the lens being only f/3.3-4.8, although in my opinion it is a price worth paying. Also the CCD shift vibration correction is very effective, with good technique long exposures are possible handheld.
I was impressed by the image quality this camera produces. Images are sharp, detailed, colourful and almost completely free of noise when the light levels are good enough to use the lowest ISO setting.”
