Hey guys. Fairly new to photography and recently purchased a Canon EOS Rebel XS w/ the standard 18-55mm lens and more recently purchase a Canon EF 75-300mm f/4-5.6 lens. I am looking for a little bit longer zoom lense say in the far end of 1000mm zoom (for sports-from the stands)and also a decent wide angle lens for group photos. Any suggestions would be appreciated such as size or brands or even places to buy on the web. Thanks in advance.
