Canon EF 70-200mm f/4L USM Telephoto Zoom Lens for Canon SLR Cameras

There are dozens of possible lens combinations and the one that's best for you depends on your particular needs and how much you want to spend. Here are three or four suggestions, but they are by no means the only good combinations. I'm sticking here with the modestly priced lenses described above which I think represent good value. Obviously you could buy all fast "L" series primes and zooms, but besides being larger and heavier, they are also significantly more expensive.
I'd say that the best low cost solution would be the 18-55 coupled with a 50/1.8 and a 75-300. This gives you one wide-angle zoom, one telephoto zoom and one fast lens ideal for portrait work. I wouldn't worry too much about the gap between 55mm and 75mm.

The best single lens solution is probably the EF 28-135 IS or the EF-S 17-85/4-5.6. The 28-135 doesn't go very wide (45mm equivalent), but it does go quite long (216mm equivalent) and it has image stabilization so you can hand hold the system in conditions where you'd need a tripod to get sharp shots with a non-IS lens. It's a very sharp lens too! If you want more at the wide end and don't care so much about the long end, then the EF-S 17-85 is the obvious choice. Of course I'd throw in a $70 50/1.8 for really low light work and portrait work where you want blurred backgrounds. I know that's two lenses, but the 50/1.8 is so small and cheap, it doesn't really count!
The best two lens solution if you want to cover all bases at reasonable cost would be to add the EF 70-300/4-5.6IS USM to the single lens package as above. You'd than have 18-300mm covered with image stabilized lenses (and of course the EF 50/1.8 II for when you need a fast lens).
The best higher end solution might be the EF-S 10-22/3.5-4.5 for the truly wide end of the range, a Tamron 28-75/2.8 Di for the mid-range and the 70-200/4L for the telephoto end of the range. If you want to stick with Canon lenses and also cover the 24-28mm range, you could pick the EF 24-85/3.5-4.5 (or the EF 24-70/2.8L, depending on the depth of your wallet!).

Lens Description

Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. This high-performance, L-series telephoto zoom lens is distinguished by such features as an f/4 maximum aperture, an inner focusing system, and a ring-type ultra-sonic monitor (USM). The last two features combine to deliver quick and quiet autofocusing--a priority for many amateur and professional photographers. In addition, photographers can attach and use a circular polarizing filter without difficulty because the front lens element does not rotate during focusing. Compatible with the same tripod collar (sold separately) used with the EF 300mm f/4L USM lens, the lens carries a one-year warranty.
