I sold my trusty 100-400mm telephoto zoom (pictured) today on Craig’s List just as Canon’s latest 70-300mm arrived on the UPS truck. The new lens is sharper, lighter, more compact, and has better image stabilization. When I travel I usually do so with a wide-angle zoom on one camera and a long telephoto zoom on the other. The new lens will get its first workout next week when the family travels to Mexico for winter break.
