If you don't mind spending some extra money, here's what I suggest, and it's from personal experience and that of two of my friends.


We all had Rebels and wanted more reach. I jumped first by going for the 70-200 F4 L. It's got excellent build quality. It focuses really fast and the image quality is outstanding. I showed my friends the pictures I got and they bought the same lens and are totally satisfied with it. If you have the 18-55 kit lens, you will only be missing 55-70 with that lens. And if you are planning to shoot pictures of your 2 year old, you want a good lens and the 70-200 F4L will give you excellent results. You buy quality and you get quality.


Hope this helps.
