Hi, I'm looking for a camera in between an compact instamatic and a full digital SLR, is there such a thing ??. I want to spend up to $800.00. It must have a good zoom lens & be pretty robust. I (try) to take a lot of action shots of my kids. I understand the Sony NEX range might fit the bill ?? Am I on the right track. Any advice pls. This is a big purchase for my wife and I and I want to make the right choice. Thank you.
