Summary: I had owned the P500 which I found just okay. It is now in the hands of my grandson. I purchased the P520 for my trip and am not happy with it. It will be returned to the shop when I get back. It is not up to Nikon quality. Having to open the viewer to disengage the viewfinder is not user friendly. Also the viewfinder is not very good. I have been a Nikon owner for m any years, but may move to another company, at least for the smaller cameras.
