The Canon EF 28-135 mm IS USM is a great choice if you are willing to give up the wide corner and you want to have a fairly universal lens with a pretty usable focal length range, as well as a flawless autofocus and very good optical features with efficient picture stabilization. It is even more tempting when we look at its price – in the digital L-grade lenses era, the price has dropped noticeably. A couple of years ago it was hard to find this lens for less than 2500 Polish zloty and now it can be purchased for as little as 1800-1900 Polish zloty.
In summation, our pictures would be of much better quality if we used the combination of the EF-S 18-55 mm kit lens and the tested EF 28-135 mm, rather than the EF-S 17-85 IS USM alone. The only drawback is the necessity of adding a weak kit lens when we need a wide view corner. We gain a much wider focal length range in telephoto mode, plus better aperture and the opportunity of saving a few hundred Polish zloty in exchange.
