The Canon EF500mm f/4L IS II USM is a very high quality super-telephoto lens that takes super-telephoto lenses to the next level. With outstanding image quality, a fast f/4 aperture and a significantly reduced weight compared to its predecessor it is a lens packed with features, optical excellence and reliability.
Who is it for?
For nature and sports photographers, especially those who travel widely, the EF500mm f/4L IS II USM makes the ideal optical tool. The 680g weight reduction compared to its EF500mm f/4L IS USM predecessor will make it highly attractive to photographers who want a more portable super-telephoto lens in their bag.

The older EF500mm f/4L IS USM is a very well respected lens, producing high quality results in all situations. The new, Mark II, lens takes that performance level and raises it to new heights to produce a lens capable of delivering results no matter how tough the assignment.
With the deployment of 16 lens elements in 12 lens groups as well as the use of two Fluorite lens elements it effectively minimises chromatic aberration and eliminates colour blurring around the edges of a subject, providing higher levels of resolution and contrast than the outgoing model.
The optical design and the placement of lens elements as well as the use of a SubWavelength Structure Coating (SWC) on the fourth group of lens elements reduces ghosting and flare when a bright light source is included within the frame.
The lens' ring-type USM autofocus motor combines with an optimized AF algorithm to provide autofocus on par with the outgoing model. The new Power Focus mode is activated from the focus mode selector switch. This mode allows the lens to adjust the focus smoothly by driving the AF motor. It can be used when shooting movies with the lens to provide a pull focus effect. Power Focus is activated by turning the focus preset ring. A small turn will drive the focus slowly, while a larger turn will provide a faster movement through the focus range.
In an effort to improve the handling of the lens, the size and weight have been reduced and the focus ring and switches have been redesigned and repositioned.
The weight reduction is 680g (from 3.87kg down to just 3.19kg) compared to the previous model and has been made possible by the use of magnesium alloy in the lens body construction. This saving of 17% makes the lens even more able to be used for hand-held shooting and also reduces the total weight of your kit bag - especially useful for travelling photographers.
Along with the reduction in weight, the closest focusing distance has also been reduced, from 4.5m on the older model to 3.7m on the new version. For photographing subjects you may wish to get a little closer too, this will prove a big benefit.
The focus ring has been moved to fit in a more ergonomic position and it has been made wider so it is easier to find with your eye to the viewfinder. The switch arrangement has also been modified. The switches are now less likely to be knocked accidentally, and the arrangement is such that the most commonly used switches are placed closer to the camera body, while those used less frequently are placed further away.
Improved durability is another area that has been addressed. The new lens features better dust and moisture proofing and a more durable IS mechanism to ensure it keeps working in all environments.
To help limit the risk of theft, the tripod collar-locking knob features a security attachment point compatible with Kensington-type cable locks. By attaching a cable lock to the locking knob rather than the lens itself, the lens can still be rotated within the tripod collar without tying the lens up in the cable lock.
Designed with the use of lens extenders in mind, the EF500mm f/4L IS II USM lens functions perfectly with the Canon's Mark III Extenders to still provide exceptionally high image quality and extra reach. With the EF1.4x III Extender you'll achieve a 700mm f/5.6 focal length and with the EF2x III, 1000mm f/8. With the EF1.4x III Extender AF and IS will function with all EOS models.
With the EF2x III Extender, AF will function at the central focusing point with the EOS 3 and all EOS-1 Series models since the EOS-1V. IS will function with all cameras since the EOS 500. To get the best performance out of the new lens with the Mark III extenders ensure that you always attach the Extender to the lens first, before attaching the whole unit to the camera. This ensures that the (combined) lens information is transmitted correctly to the camera body to provide the optimum image quality and focus performance.
A ring-type USM autofocus motor, combined with a high-speed CPU and optimised AF algorithm, delivers fast and near-silent AF with precision. It also provides full-time manual focus so that you can adjust the focus with the focus ring, without first having to switch the lens to manual focus. This allows you to adjust the focus accurately to ensure it is exactly where you want it to be for the most creative control possible. The addition of Power Focus mode allows you to activate a motor driven focus shift for use when shooting movies.
The Image Stabilizer in a Canon lens works by shifting a stabilizer group of elements to compensate for motion detected by a gyroscope in the lens. There are now three IS modes - Mode 1 for general shooting, Mode 2 for panning and Mode 3 which is ideal for sports photographers.
The panning mode, Mode 2 features a modified IS algorithm as well. This new algorithm negates the IS ‘bump' that can occur when you first start panning the lens providing a more stable viewfinder image. The new IS mode, Mode 3, only activates the IS mechanism when you full depress the shutter button to shoot an image. For sports photographers moving between shots, this avoids the lens trying to stabilize random, rapid movements and only begins to compensate while you are shooting.
Once activated, the Image Stabilizer gives up the equivalent of four stops of shutter speed so you can handhold and capture acceptably sharp images at much slower shutter speeds. For movie shooting with a tripod, the IS mechanism can be left switched on. The lens will detect it is mounted on a tripod and the IS optics will be locked in place so they cannot move. If vibration is detected the IS will then activate to remove vibrations.
Keeping lenses clean is important to ensuring the best image quality possible. To help with this, both the front and rear lens element are coated with fluorine which acts as a non-stick, easy to clean surface to help with the removal of dust and dirt or oils left by fingerprints or from the atmosphere. Fluorine is also used on the filters covering the CMOS sensor camera and the rear LCD panels of several EOS models for the same reason.
SubWavelength Structure Coating
Designed for use in digital photography, Canon's patented lens element coating helps to prevent the ghosting and flare caused by internal reflection - helping to deliver crisp, clear images. The EF24mm f/1.4L II USM was the first Canon lens to feature the SubWavelength Structure Coating and it is now found on several lenses in the range. This coating reduces reflection from the surface of the lens - it has the advantage of reducing both flare and ghosting to improve image quality.
