<h2>Hey everyone,</h2>
<p>I recently purchased a canon 7D with the Canon 24-105mm lens and wanted to get a telephoto lens as well to compliment my current lens. I was wondering if anyone had any suggestions for me or if a telephoto lens would even be necessary at all given the 105mm (168mm on a crop) focal length. I will be heading out on a 1 month backpacking trip and will be taking mostly landscape shots. I have read that the canon EFS 55-250mm is a great lens for the camera but am not sure if that would be too much overlap. The prices for that lens is very attractive. Any help would be much appreciated.</p>
