I want to start photography as an hobby. So to start I need a camera. I now a reflex would be the best, but I have no idea what to look for: pixels or ISO. What would the most adapted lens for landscape pictures. I'm ready to spend a maximum of 500$ in a camera.
More Pixels are only useful for printing bigger images at a given print quality. 10 or 12 MP (megapixels) is enough for normal sized prints. Manufacturers add more MP to attract new buyers who think MP is very important. If you search a lot, even pro cameras like the Nikon D4 only have 16-20 megapixels.
