Featuring Fluorite optics that deliver sharper images with less chromatic aberration, the new large-diameter EF 600mm f/4L IS II USM super telephoto lens also takes advantage of magnesium and titanium construction for a lighter weight and a Fluorine coating that keeps soiling, smears and fingerprints to a minimum. Because image stabilization technology in super telephoto lenses may inadvertently over-compensate and interfere with composing and framing distant or moving subjects, the EF 600mm f/4L IS II USM includes an advanced third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed. This allows users to pan fast-moving subjects and then activate IS only when it is precisely required. Because all three IS modes give the equivalent effect of up to four extra stops of performance, and because plus the Power Focus mode enables smooth focus change when shooting video, the EF 600mm f/4L IS II USM is ideal for capturing rapid-fire action. Other improvements such as better dust- and waterproofing make the Canon EF 600mm f/4L IS II USM super telephoto lens an ultra high-performance Digital Age tool combining Canon hallmarks of superb ease-of-use with excellent durability.
Compact lightweight super-telephoto
The EF 600mm f/4L IS II USM features a lightweight magnesium alloy and titanium construction, which reduces weight without compromising on strength and build quality.
Sophisticated optical design
A complex optical design that features fluorite and UD lens elements to tackle aberrations and distortions. A fast f/4 maximum aperture enables use of the Canon Extender EF 2.0x III while retaining AF on EOS-1 series cameras.
Built-in Image Stabilizer technology enables hand-held shooting with shutter speeds up to four stops slower than normal without incurring camera shake. Multiple IS modes improve image quality when panning.
The L-series is Canon’s flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are highly resistant to dust and moisture.
The EF 600mm f/4L IS II USM’s two-speed Power Focus mode allows focus to be adjusted at a smooth constant speed – perfect when shooting video.
Fast, quiet auto focus
A ring USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive extremely rapid auto focus with near-silent operation. A high-speed CPU and optimised AF algorithms contribute further to AF speed. Full time electronic manual focus override is available without having to switch out of AF.
3 IS Modes
Ideally suited for all types of action photography especially those disciplines that require the utilization of panning, the new IS mode 3 only activates the image stabilizer element during exposure.
Enhanced image quality with SWC coating
Designed for use in digital photography, Canon’s patented Subwavelength structure coating helps minimise the ghosting and flare caused by internal reflections. By eliminating the cause, the coating reduces reflections and helps to deliver crisp, clear images.
