With the arrival of the Canon EF-S 17-55mm 1:2.8 IS USM lens, my photo equipment is finally complete. For now.
I also tested the Canon EF-S 15-85mm 1:3.5-5.6 IS USM which is one of the Canon EOS 7D kit lenses. It's a very nice lens, with great wide-angle and a good zoom range, but unfortunately it's less suitable for the available light photography I do primarily.
Besides my trusty Canon EF 50mm 1:1.4 USM for portraits, there's the Canon EF 70-300mm 1:4.0-5.6 IS USM telezoom lens. These three lenses cover most kinds of photography I like to do regularly.
Here's my updated Amazon Favorite List.
