I am wanting to upgrade my camera. I currently have a Canon Rebel 1000D. I have decided to get the Canon 7D but cannot decide if I should just get the body or buy the kit with the lens included. The lenses I currently have include Canon EF-S 18-55mm f/3.5-5.6, Canon EF 50mm f1.4, and Canon EF 75-300mm f/4-5.6. The Canon 7D I'm looking at is listed as $1350 for just the body or $1550 with the 28-135mm kit lens. I'm just wanting some advice as to whether or not you all think it is worth it to spend a little extra to get that lens or not considering the lenses I already own. The lens included in the kit retails for around $360 online right now. Any advice is GREATLY appreciated. Thanks!
