hey guys! I'm somewhat new to photography; however still a beginner (I say somewhat because I stopped for a while & now I'm getting back to it) and I'm thinking of purchasing a new camera. I have narrowed it down to a Cannon T3i. This camera has several lens packages and I'm overwhelmed with all the choices. Can someone please explain the difference between the ES-S 18-55mm; the 75-300mm; the 55-250mm telephoto zoom lens & the 18-135mm lens. The two packages I'm really interested in are: the T3i body with the 18-55mm, 75-300mm and the 55-250mm telephoto zoom lens; and the second package includes the T3i body with 18-135mm & 75-300mm lens. they are separated by $150, which is the better purchase and why?
