A first glance at this little camera from Pentax will leave you wondering if it is even water proof, forget about nature proof. It is a shiny little thing, but guess what; a day in your kitchen sink will leave it high and dry still. A drop on the ground – don’t try this too many times, though, you never know – will leave the camera unshaken, and twists and bends and shakes will have absolutely no effect on the sturdy little gadget from Pentax. Do all this and you will come to believe that the thing may, after all, be nature proof. You can take this camera to extreme weather conditions. Extreme cold – think Alpine ski holidays; and extreme heat – think a Sahara desert blitzkrieg; you will still have your Pentax Optio 190 working away smooth as a breeze. Even cute underwater expeditions in the Bahamas or some serious diving off the coast of Tahiti will not mess up your camera. It will still go on working, taking high quality pictures with its advanced image shooting system. The camera delivers steadily in extreme lighting conditions like underwater or deserts, or even the glare of snow. There is an amount of image noise, which is a result of high ISO speed, and can go away to a large extent if the film speed is set low. Overall, this is a smart digital camera that delivers a good quality performance while remaining totally nature proof. A recommended, if not a must, buy.
