Alright so I am planning on buying the Rebel XSi and am thinking about lens. I was going to get the kit lens but now i cant decide between getting the kit lens or getting the camera body with a 75-300mm telephoto USM Zoom Lens. I am going to be shooting mainly wildlife like birds or other types of animals but I was wondering- can I use a telephoto lens for landscapes and urban scenes? Because I also want to try those out and I dont know how well the telephoto lens would work in those situations. Thanks!
