Canon EF 500mm f/4L IS II USM Lens The EF 500mm f/4L IS II USM is a high-magnification, super-telephoto lens featuring integrated Image Stabiliser technology and a fast f/4 maximum aperture. It features a lightweight magnesium alloy and titanium construction, which reduces weight without compromising on strength and build quality, while its optical design includes fluorite and UD lens elements to tackle aberrations and distortions. In addition, Canon’s patented Sub wavelength structure coating helps minimise the ghosting and flare caused by internal reflections. The Canon EF 500mm f4 L IS II USM Lens features built-in Image Stabiliser (IS) technology that enables hand-held shooting with shutter speeds up to four stops slower than normal. Part of Canon’s flagship L-series professional lens range, the Canon EF 500mm f4 L IS II USM Lens is perfect for wildlife, nature and sports photographers working in the field.

Sophisticated optical designA 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. Fast, quiet auto focusA 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. Image StabiliserBuilt-in Image Stabiliser 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. IS Mode 3Ideally suited for all types of action photography especially those disciplines that require the utilisation of panning, the new IS mode 3 only activates the Image Stabilizer element during exposure. Enhanced image quality with SWC coatingDesigned for use in digital photography, Canon’s patented Sub wavelength 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. Power focusingThe EF 500mm 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. L-series qualityThe 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 resistant to dust and moisture.
