Canon 200-600 f/4.5-5.6 Super Telephoto PatentLooks like the eager response to the new Nikon 200-500 has caused Canon to seek to "one-up" its rival again ...
Canon's recent telephotos have been wonderful, so if the recent 100-400 II (and 200-400 + 1.4x) are any indication, this may be a wonderful mid-level telephoto option.
