I rented a 100-400mm Canon lens for a trip to Glacier National Park in Montana. The lens arrived exactly as promised, a day before we left. It was in constant use for a week as I got great shots of moose, bears, bighorn sheep, mountain goats, pronghorn, eagles and more. We spotted a grizzly far up on a slope -- barely a dot to the naked eye, but at 400mm I got a perfect, clear shot. On another occasion, a black bear lumbered onto a trail 30 feet in front of us. Even as we were carefully backing away and successfully shouting the bear off, the lens allowed me to keep shooting sharp pictures at the same time. Your service made a special trip even better because of the memories we were able to bring home. Returning the lens couldn’t have been easier – with the prepaid shipping, I just dropped it at a FedEx location on the way home. As we continue our quest to visit and photograph as many national parks as possible, CameraLensRentals.com definitely will be part of every trip.
