I am an experienced photogapher who owns an Olympus digital camera with 2.1 megapixels. I wanted to upgrade to a higher resolution and the 10X Zoom. So, I got the Nikon S4. But, the photos are grainy with a lot of noise. I find the scene choices virtually meaningless. I am selling my S4 on eBay so keep an eye out for a real bargain. I'm going back to my trusty Olympus. And, another tip, never, ever buy a camera with an LCD display only. They are impossible to see in bright sun.
