Canon has announced updates on two of its heaviest hitters: the Canon EF 500mm f/4L IS II USM and EF 600mm f/4L IS II, both of which are far lighter and nimbler than their predecessors.
The new L-series super telephotos incorporate a number of improved imaging technologies, including chromatic aberration-reducing fluorite elements, fluorine coatings for easier removal of smudges and fingerprints, weight-reducing magnesium and titanium construction, and enhanced weather-proofing.
Other important improvements found on Canon’s latest super-telephotos include “Mode 3” Image Stabilization, which along with a 4-stop advantage when shooting under lower lighting conditions, only kicks in when the shutter button is fully depressed, making it easier to frame subjects while panning quickly. There’s also a new Power Focus Mode that facilitates easier focusing when shooting in video.
The Canon EF 500mm f/4L IS II USM (5°AOV) contains 16 elements in 12 groups, has a minimum focus of 12.1’ (3.7 m), and weighs 7 lb (3190 g). The new Canon new EF 600mm f/4L IS II (4° 10’) contains 16 elements in 12 groups, focuses down to 14.8’ (4.5 m), and weighs 8.6 lb (3920 g).
To facilitate equal ease of use on tripods and monopods, Canon is also offering optional long- and short-foot tripod mounts, and to reduce the possibility of disappearing acts, each lens is equipped with a Kensington-type security lock.
