After much hesitation, I really need another lens? I have but then slammed in a range action. Now I am not a professional, but collect my experiences in everyday life and I have to say that I feel my 7D has been waiting for this "partner". While I have nothing else to complain, only the combination is the maximum suitable for everyday use what I have experienced so far. The 3mm more in the lower region as compared to the 18-135 or 18-55 make itself felt and the "missing" in the upper part to the 135 hardly disturbs. If I need it I'm going straight to a telephoto. Thus my conclusion: I have not looked back.
