What's New and Different

Canon EF 100-400mm f/4.5-5.6L II USM Lens The much-rumored Canon EF 100-400mm f/4.5-5.6L replacement lens has officially arrived. Released in 1998, the initial trombone-style lens has been replaced by a more traditional zoom with rotating layout and features several optical enhancements. The lens is somewhat taller, wider and weighs more than the original, however the change to a zoom which rotates should alleviate issues with dust being drawn in during shooting. It also features three image stabilization methods and delivers 4 stabilization stops in comparison to 1.5 in with the first version. The new lens will also automatically lock in the IS elements as it ascertains a tripod in being used. Minimum focus distance has been improved to just 3.2 feet (as compared to a longer 6.5 ft) while the lens features maximum magnification of 0.31. A brand new bayonet-type hood (ET-83D) is also included, featuring a slot allowing for easier filter adjustment. 

The New EF 100-400mm f/4.5-5.6L II features a totally brand new optical formula using one Fluorite and a single Super UD element. A new Air Sphere Coating (ASC) application has been introduced which makes use of suspended air bubbles within the coating itself. The advantages are a reduction in flaring and ghosting, similar to how Canon's SWC (Subwavelength Structure Coating) is used in their wide angle lenses.

What's New and different
The new lens contains 21 elements within 16 groups which makes the lens is somewhat heavier (3.46 as compared to. 3.1 pounds) and bigger (3.7x7.6 as compared to. 3.6x7.4 inches) although that's a modest concession for an improved internal AF focusing system with ruggedization, a closer minimum focus, and a more state-of-the-art image stabilization (Canon now claims up to 4 stops of photo correction). There are three image stabilization functions (standard, panning, and only during exposure) are claimed to deliver steady handheld images over a wide spectrum of shooting environments.

As with the previous lens, the new one features one fluorite and a single super UD element, working to deliver impressive resolution, contrast and diminished chromatic aberration over the entire zoom spectrum. Additionally, Canon has added ASC (Air Sphere Coating ), which they claim will significantly diminish backlit ghosting and flaring . Fluorine coatings on both the front and the rear lens coverings have been added to reduce fingerprints and smears . (As an extra precaution, I recommend a using a Sky or UV filter to safeguard the front element.) Other helpful new additions include a re-engineered tripod mount which can be coupled and decoupled without separating the lens and camera, and a brand new lens hood featuring a side window making it easy to adjust polarizers along with other specialty type filters without removing the hood. Handling enhancements include a rotating-type zoom ring featuring an adjustable zoom torque delivering more exact, customizable zoom realization and the zoom torque ring adjustment has been upgraded to allow easier zoom tension settings . The lens will be available in December for around $2199.

Press release


New Super-Telephoto Zoom Lens Delivers an Enhanced IS System Providing Four Shutter Speed Steps of Correction, a Rotation-Type Zoom Ring, and New Optical Element Formula to Help Maximize Image Quality

MELVILLE, N.Y., November 10, 2014 ─ Canon U.S.A., a leader in digital imaging solutions, today announced the highly anticipated Canon EF 100-400mm f/4.5-5.6L II USM lens, a second generation compact super-telephoto zoom lens featuring significant advancements in optical quality, image stabilization performance up-to-four steps, and rotating-zoom-ring design. This new L-series super- telephoto zoom lens features Canon L-series weather resistance and rugged magnesium housing to meet the needs of wildlife and sports photographers or photojournalists working out in the elements. Fully compatible with all EOS cameras, the EF 100-400mm f/4.5-5.6L II USM features a completely redesigned optical formula containing one Fluorite and one Super UD lens element ─ a combination unique to lenses in this focal range ─ to help deliver sharp images with high resolution and contrast. This combination of elements helps thoroughly suppress chromatic aberration throughout the entire zoom range.

“The Canon EF 100-400mm f/4.5-5.6L II USM is the logical evolution of the very popular EF 100-400mm f/4.5-5.6L IS USM introduced 16 years ago,” said Yuichi Ishizuka, President and COO of Canon U.S.A., Inc., “This long awaited, next generation lens was developed to be a highly portable and adaptable telephoto zoom lens for today’s modern professional and advanced amateur photographers.”

For photographers who want to work as closely as possible to their subjects, the minimum focusing distance of the lens has been reduced to just 3.2 ft. (0.98m), resulting in maximum magnification of 0.31x. The original EF 100-400mm f/4.5-5.6L IS USM was well known for its push-pull zoom adjustment, but the EF 100-400mm f/4.5-5.6L II USM uses a rotation-type zoom ring similar to the one found on the EF 70-300mm f/4-5.6L IS USM lens that allows for more precise adjustments, easier handling, and consistently excellent weight balance during handheld photography. In addition, the lens features an improved zoom torque adjustment ring that allows for the easy setting of zoom tension based on personal shooting preferences. The Canon EF 100-400mm f/4.5-5.6L II USM also features an inner focusing system, a powerful yet quiet Ring USM, a high-speed CPU and optimized auto focus (AF) algorithms for fast and accurate autofocusing in various shooting situations.

The Canon EF 100-400mm f/4.5-5.6L II USM features three Image Stabilization (IS) modes ─ standard, panning, and during exposure only. Each IS mode is individually engineered to help provide outstanding results in a wide variety of shooting situations, and all serve to satisfy the personal preferences of photographers based on the type of IS they desire. The optical IS provides up to four shutter speed steps of correction, increased from 1.5 steps in the previous model*. In addition, the EF 100-400mm f/4.5-5.6L II USM features Canon’s newly developed Air Sphere Coating (ASC) which helps to reduce backlit flaring and ghosting significantly, as well as a 9-bladed circular aperture Electro-Magnetic Diaphragm that helps to enhance beautiful, softly blurred backgrounds.

As with all L-series lenses, the Canon EF 100-400mm f/4.5-5.6L II USM is highly resistant to dust and water, with excellent durability in even harsh conditions, ideal for wildlife photographers even in rainforest environments, or sports photographers on the sideline grabbing action shots of the big game. Fluorine coating on the front and rear surfaces of the lens can repel dust particles and water droplets. It also makes smears and fingerprints easy to remove without the use of lens cleaning fluid. Included with the lens is the new ET-83D lens hood, that features a cleverly placed and convenient side window allowing the user to easily adjust specialty filters while the lens hood remains in place. In addition, the EF 100-400mm f/4.5-5.6L II USM is equipped with a newly designed detachable tripod mount which can be removed to reduce weight during handheld operation.

Pricing and Availability

The Canon EF 100-400mm f/4.5-5.6L II USM Super-Telephoto Zoom Lens is scheduled to be available in December 2014 for an estimated retail price of $2,199.00. For more information, please visit
