Having just returned from a great trip to California, the first thing awaiting my return was a new Canon EF 100-400mm F/4.5F IS USM Zoom Lens , a lens ordered specifically for that trip and arriving a day late. My wife had made it an especially great moment as she the picture you see here on her FaceBook Page, knowing that I would pine to get my hands on it while in California. Being married more than a few years, she knew that every shot I took this past week would leave me longing for that lens. Not even on the ground a full 12 hours, we were off to the Bird Kingdom in Niagara Falls for some first hand testing of this new monster lens.
