Rent a Canon 600 f/4 L IS II at LensProToGo.com

Canon's update on their previous beast of a lens. The new version weighs in at about one-third lighter than the previous generation. That translates to a TON of weight gone off your shoulder as you are lugging this thing around the wilderness. Super sharp optics and super fast AF performance. Canon used more flourite optics in the newer version of lenses which means less chromatic aberration (highlight fringing) and wide-open vignetting. Canon also added a third IS mode which is only activated when the shutter button is fully pressed. This gives you 4 stops of IS without the lousy camera battery drain. This might be the best wildlife lens out there.

PLEASE NOTE:
Unlike our other lenses, the super telephoto lenses will be shipped in soft cases which can be used to transport the lens during your rental period.
