I must say that I am really impressed with the P510. The zoom range is of course gigantic and despite these values in my opinion the image quality for the home users is absolutely sufficient. Sure like very abitionierte amateur photographers and even professionals have in mind any complaints, for me it is enough but all times. The light intensity is also sufficient to avoid having to constantly strive to flash, even at longer focal lengths.
I do not regret the change and would highly recommend this camera with a clear conscience.
