Title: An outstanding lens
Review: When I say outstanding, I'm comparing it with my 24-105 f/4 L IS lens, my 28-75 2.8 Tamron, the original 17-85mm f/4-5.6 IS kit lens and just for a high bar my 70-200 f/2.8 IS L (nothing beats that one). I've found that when using the EF lenses on a cropped sensor camera like my 30D and 20D, some of the "lesser" lenses perform very well because they're using the center "sweet" spot of the lens. Taking this into consideration for this review, I've found it very hard to tell the difference in photos between the 24-105 L lens and the 28-135 non-L lens. The 24-105 L lens is built more sturdily, has the constant f/4 apperature, and has extra weather-proofing but the 28-135 lens is less than half the cost, has IS, and gains 30mm in zoom. So seriously, if you aren't thinking about buying your lenses for the day when you upgrade to a full size sensor camera body, the 28-135 lens, for the price, is a fantastic deal.
