DCResource have reviewed the tiny 4 megapixel Pentax Optio S4i, which has a 3X optical zoom, 1.8 inch LCD monitor and features the first PENTAX digital cradle-style lithium ion recharge base unit.

“Life is full of compromises. In the case of the Optio S4i, you’re trading photo quality for camera size. The photos aren’t bad by any means, and will make nice smaller prints and web photos. But if you make big prints or like inspecting photos at 100%, then this camera may not be for you. Why? For one, there’s the blurry corners that I mentioned. The camera also has a bit of a noise problem, overprocessing images to the point that they look like watercolors. The noise does all kinds of weird things, most notably eating away at details, as you can see in my samples above.”
