I have a simple point and shoot Fuji camera that is about 2 years old, good for the basics and day to day. But I'm going on a couple big trips and would like to get a more advanced camera to shoot some scenery, landscapes and building/ruins (Paris, Greece, Italy, Ireland). I'm willing to spend about $500 on a camera, but dont know the first thing to look for, do i need an SLR camera? Can you please help?
