Hello folks, After having used the Canon 400D kit lens for about 3 months I would like to go in for my next investment on a lens. The budget would be around $250 - $300 range. Since the kit lens being a wide angle can zoom very little I wanted to go in for a better zoom range. When searching for a lens I found the 70-300mm F4-5.6 APO DG MACRO ($300) quite a fit. I was also excited about the lens's MACRO facility at the 200-300mm range. Would this be a good lens to buy or would you suggest any other Canon lense with a comparable zoom?
