Your Second (and Third...) Lens

There are really only two advantages to owning just a single lens. One of them is creative. Keeping one set of optics mounted on your T3i all the time forces you to be especially imaginative in your approach to your subjects. I once visited Europe with only a single camera body and a 35mm f/2 lens. The experience was actually quite exciting, because I had to use a variety of techniques to allow that one lens to serve for landscapes, available light photos, action, close-ups, portraits, and other kinds of images. Canon makes an excellent 35mm f/2 lens (which focuses down to 9.6 inches) that’s perfect for that kind of experiment; although, today, my personal choice would be the sublime (and expensive) Canon Wide-Angle EF 35mm f/1.4L USM Autofocus lens. I also own the Canon EF 50mm f/1.8 II lens, which I favor as a very compact and light walkaround/short telephoto/portrait lens, especially indoors. It makes a great close-up/macro lens, too, and, at $100, is my choice as a very good second lens.

Of course, it’s more likely that your “single” lens is actually a zoom, which is, in truth, many lenses in one, taking you from, say, 17mm to 85mm (or some other range) with a rapid twist of the zoom ring. You’ll still find some creative challenges when you stick to a single zoom lens’s focal lengths.
