I have been using a Sony Cyber Shot DSC-S3000/S which is a 10.1 mega pixel, 4X optical zoom lens, since last one and a half years. And now I really want to upgrade my photography skills by using an upgraded and the best digital camera available. I have a budget of about $500 and it can be extended upto $600 if worth it. It should be a digital camera of more than 12 mega pixels, with 4X optical zoom, and it should also be user friendly with not much complications to handle. I’ve heard of Samsung PL20, Nikon L24, Canon A2200 which are the latest models launched. Which one of them would be the best suited for me?
