The inspiration behind Canon’s RF 600mm F11 and 800mm F11 super-tele lenses

06 Oct

In July, Canon announced a pair of super-telephoto fixed-aperture lenses for its RF lens mount. The new RF 600mm F11 IS STM and RF 800mm F11 IS STM lenses are distinct among Canon’s modern offerings but are reminiscent in design and philosophy to some of Canon’s R lenses from 1960.

Six decades ago, Canon released the R300mm F4, R400mm F5.6, R600mm F5.6, R800mm F8 and R1000mm F11 super-telephoto lenses. While not fixed aperture lenses like the new RF lenses, the vintage bellows-driven lenses were nonetheless the inspiration for this year’s modern interpretations. In a Japanese-language interview published by DC Watch, Canon’s Chief of Lens Product Planning, Kengo Iezuka, notes that the EOS R system allows him and his team to create new user experiences for modern photographers. This includes breaking down ‘the three barriers of super-telephoto lenses,’ which he states are weight, size and cost. In 1960, Canon worked to overcome these challenges with its R lenses, and Iezuka believes Canon’s RF 600mm F11 and RF 800mm F11 lenses do the same in 2020.

When Iezuka was a child and wanted to capture wildlife images of a Little Egret, he was unable to due to the expense of super-telephoto lenses. Iezuka says via translation, ‘I knew that there were many people who gave up what they wanted to shoot and the expressions they wanted to shoot because they couldn’t buy a super-telephoto lens and couldn’t carry it because it was big and heavy. With the EOS R system, I think I was finally able to get closer to the dream super-telephoto world. I would like you to enjoy shooting things that you couldn’t shoot before and the expressions you wanted to shoot with this 600mm/800mm F11 lens.’

In elaborating further upon how the Canon EOS R system allows the three barriers of super-telephoto lenses, Iezuka states that Canon’s Dual-Pixel CMOS AF allows for strong autofocus performance even in low light, or when using a lens with a smaller maximum aperture, such as F11. In 1960, the sensitivity of film was stricter, requiring faster apertures in the case of the R400mm F4.5, R600mm F5.6 and R800mm F8. However, today, Canon’s EOS R system allows for much more flexibility when designing new lenses. In fact, the EOS R can even work with F22, allowing Iezuka and his team to utilize an F11 design that can incorporate a 2x teleconverter.

If Canon had pursued an F8 aperture, the lens would have been larger and heavier. An F16 lens would have worked without a teleconverter, but not with a 2x TC attached. It was around this point in the design process when the team first considered making the lens with a fixed aperture. Ultimately, removing the aperture unit allowed for reduction in weight and cost, both critical design goals for Iezuka and the team at Canon.

Iezuka also shared that the RF 600mm and 800mm lenses were not his first attempt to create a lightweight and cost-effective super-telephoto lens. He had previously explored the idea for SLR cameras. ‘I wondered if I could manage to get closer to the world of super-telephoto lenses that exceed 400mm,’ Iezuka said, ‘I considered increasing the F-number as I did this time, but it didn’t work. If you increase the F value, you can only autofocus at the center of the [frame]…so I gave up.’ The new RF lenses offer autofocus coverage of 60% x 40% (W x H) with the recent Canon EOS R5 and R6 full-frame mirrorless cameras.

Iezuka also considered zoom lenses, but this design would increase the weight too much to be able to carry the lens around all day. The RF 600mm lens weighs approximately 2.05lb and the RF 800mm weighs about 2.78lb. In order to maintain a lightweight design and ensure the lenses are affordable, metal parts are kept to a minimum and much of the lens is constructed using resin. In order to utilize a collapsible design, many parts had to be molded, which is unique for Canon’s lenses. The collapsible design came from one of the youngest members of the team, Iezuka says, and was the result of internal competition within the department.

There is much more excellent insight into the design process in the full interview, so be sure to check that out. Click the following links for more information on the Canon RF 600mm F11 IS STM and RF 800mm F11 IS STM lenses.

Designed as a lightweight and affordable extreme telephoto prime for Canon RF-mount shooters, the Canon RF 600mm F11 IS STM is a versatile lens for casual wildlife and general photography. If 600mm isn’t enough for you, it can be paired with Canon’s new 2X extender for RF to become a very portable (and very slow) 1200mm F22. While not up to the same optical standard as Canon’s more expensive fast sports primes, we’re pretty impressed by what this budget tele can do.

Birds, spiders, cats, squirrels, planes, boats, distant mountains and (naturally) the moon. These are just a few of the things that we pointed the Canon RF 600mm F11 IS STM at this weekend, and you can take a closer look in our sample gallery, which includes several images taken with the new 2X converter.

Lensrentals tears down the Canon 600mm F11 IS STM

25 Aug

Roger and Aaron of Lensrentals are back with a new lens teardown, the Canon 600mm F11 IS STM. While it’s not the lens Roger usually goes for (he’s a self-proclaimed connoisseur of ‘high-priced wide-aperture lenses’), this lens fills a niche in the photography world and both Roger and Aaron were interested to see how exactly Canon packs a 600mm focal length into a compact body that weighs just 2lbs.

Before any screws are removed, Roger breaks down the new gapless diffractive optics Canon uses inside the lens. Instead of the first-generation of Canon’s diffractive optics technology, the 600mm uses gapless diffractive optics, which Roger says is ‘basically market lingo for ‘instead of an air space between the DO elements, we invented some special glue.’

An illustration from Canon showing the difference between the first-generation DO optics and the second-generation ‘gapless’ DO optics.

It wouldn’t be a Lensrentals teardown without a few hiccups along the way and this proved no exception. Due to the unique extending-barrel design of the lens, the teardown proved to be a bit more of a learning curve.

The twist-and-lock ring used for extending and locking the lens in place for used being removed.

After getting through the rear lens mount, it was onto the extending section of the barrel. Canon uses a series of metal guides to stabilize the lens when extended. Roger notes these were ‘quite solid pieces of metal going the length of the lens.’

A close-up look at the guides that run along the length of the lens and provide structural integrity when extended.

As you would expect for such an interesting design, the ribbon cables inside were a bit more challenging to trace out than the typical Canon lens. Roger and Aaron made it halfway through the lens before eventually offering up ‘some 4-letter prayer words to the high priests of Canon engineering, because, well, nothing was coming apart.’

So, rather than risking further damage, the duo turned the lens over and started tearing it down from the front of the lens. As was expected after seeing the initial flex cable running down the lens, the electronics of the lens proved to be much different than what’s often seen inside Canon glass, with interesting angles, plenty of tape and even flex solder being used. Despite the differences though, Roger notes that the lens is very much a Canon lens in the optics department.

A close-up view of the front-most element, which in this case is the diffractive optics group.

The duo had gotten as far as they could before Roger was due to leave, so they wrapped it up. In Roger’s summary, he notes that the lens’ electronic construction was very different for a Canon lens, while the optics had a ‘very Canon look, with numerous optical adjustments/compensations using their new, large eccentric collars.’ Roger says he’s convinced these new larger collars are used ‘because Canon is doing automated optical adjustment of subgroups during assembly.’ He adds that ‘nobody else is adjusting to this degree or in this manner.’

Canon introduces RF 600mm and 800mm F11 IS STM lenses, 1.4x and 2x teleconverters

13 Jul

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_4218148383″,”galleryId”:”4218148383″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Canon has announced a pair of super-telephoto fixed-aperture lenses: the RF 600mm F11 IS STM and RF 800mm F11 IS STM.

The use of gapless dual-layer diffractive optics and fixed apertures of F11 allowed Canon to reduce the size and length of the lenses compared to their EF equivalents. Canon also says the design of the DO elements also allows for much lower pricing than would otherwise be possible. Both lenses are collapsable, which reduces their stowed length by around 25%. Neither is weather-sealed.

The design of the DO elements also allows for much lower pricing

The image stabilization on the lenses reduces shake by five stops on the 600mm and four stops on the 800mm. Canon does not claim any additional image stabilization advantage when using the IBIS systems in the newly launched EOS R5 and R6. Both lenses use stepping motors to drive their focus groups, so focus is unlikely to match the speeds and silence of the company’s lenses using Nano USM motors. When attached to the R5 and R6, AF coverage area is 60% x 40% (W x H).

The RF 1.4x and 2x will give the 600mm F11 and 800mm F11 even more reach

Canon has also introduced a pair of teleconverters alongside the RF lenses released today. The RF 1.4x and 2x will give the 600mm F11 and 800mm F11 even more reach. With the 2x teleconverter attached, the 800mm F11 becomes a 1600mm F22 – and yes, the R5 and R6 can maintain autofocus at that aperture.

The teleconverters are also compatible with the just-announced 100-500mm F4.5-7.1L. Note, however, that the 100-500mm must be set to 300mm or longer before the teleconverter can be attached, so the lens becomes either an effective 420-700mm or a 600-1000mm, depending on which converter you’re using.

The 600mm, 800mm and both converters will be available later this month. The 600mm is priced at $ 699, while the 800mm comes in at $ 899. The 1.4x and 2x converters will sell for $ 499 and $ 599, respectively.

Hands-on with new Canon RF 100-500mm, 600mm and 800mm telephoto lenses

10 Jul

Hands-on with new Canon RF 100-500mm, 600mm and 800mm telephoto lenses

Alongside the EOS R5 and R6, Canon has announced a brace of lenses, all in the short to long telephoto range. Filling out the ‘long’ end are one L-series zoom, and two innovative primes. Click through to learn more about the 100-500mm F4-7.1L IS USM and the RF 600mm and 800 F11 IS STM.

100-500mm F4-7.1L IS USM

Let’s start with the more conventional lens of the trio – the 100-500mm F4-7.1L IS USM, which first appeared in mockup form at events earlier this year (remember when we had events?) featuring 20 elements in 14 groups, this is a complex design, which incorporates six UD (Ultra Low-Dispersion) elements and one ‘Super’ UD element. These elements should help control chromatic aberrations.

(Relatively) compact

The 100-500mm is relatively compact when zoomed ‘out’ to 100mm (207.6mm / 8.2 in) but extends (to 297mm / 11.7 in) at 500mm. A torque adjustment allows you to make the zoom movement stiffer or looser as desired, and lock the zoom ring if required.

Canon is at pains to reassure users that despite its telescoping design, this lens is very well-sealed against dust and moisture. At 1370 g (3 lbs), the 100-500mm is far from a lightweight lens, but it’s only a couple of hundred grams heavier than the much faster RF 70-200mm F2.8L IS USM. The front filter thread is a very reasonable 77mm.

A removable tripod collar allows the lens to be mounted directly onto a tripod, in situations where hand-holding isn’t desirable or practical.

Close focusing performance

Considering its focal length range, the 100-500mm offers good close focusing performance, with a minimum focus distance of 0.9m at the 100mm end of the zoom, and 1.2m at 500mm. This should make it practical for conventional short-tele portraiture. The maximum magnification ratio of 0.33X is achieved at 500mm (full extension at 500mm shown in this image).

Autofocus is handled by dual Nano USM motors that can work independently of one another for fast and silent AF.

5 stops of IS

This is a stabilized lens, rated at 5 stops of correction on an EOS R. When mounted on an R5 or R6, Canon claims that total stabilization with its I.S.-enabled lenses should improve due to both in-body and lens IS systems receiving information from the others’ sensors.

This two-way communication is enabled by the fast protocols developed for the RF mount. Canon quotes as much as an 8 stop benefit with some lenses. Canon claims you can expect 6 EV of correction from the 100-500mm and R5/6 combination, and this is something we’ll be sure to test as soon as we can. There are three IS modes to choose from: standard, panning or active during exposure.

Compatible with RF 1.4X and 2X teleconverters

The 100-500mm is compatible with Canon’s new RF 1.4X and 2X teleconverters, but only at focal lengths of 300mm and longer. A locking mechanism prevents their use at wider focal length positions, where damage might occur to the lens’ rear element.

The RF100-500mm F4.5-7.1 L IS USM lens is scheduled to be available in September 2020 for an estimated retail price of $ 2,699. The RF Extender 1.4x and 2x are scheduled to be available at the end of this month for an estimated retail price of $ 499.99 and $ 599.99.

Canon RF 600mm F11 IS STM

Alongside the 100-500mm Canon unveiled two very unusual lenses, both of which employ collapsible mechanisms and DO – Diffractive Optics – elements in their designs, to reduce their size and weight. The first is the RF 600mm F11 IS STM. Canon claims that the use of a new material for the gapless dual-layered DO element allows for smaller and more cost-effective designs compared to the EF equivalents.

Compact and lightweight

The 600mm F11 IS STM weighs less than a kilo (930 g / 2.05 lbs), features a perfectly reasonable 82mm filter thread and measures only 200mm (7.9 in) when stowed. Considering its focal length, these figures are impressive. The DO optical technology certainly helps, but the main reason for its unusual compactness is an innovative retractable design.

Retracting design

Retracting / collapsing designs have been around for as long as photographic lenses have existed, and the basic principle (and benefit) has remained the same – extend and lock the mechanism when you need to shoot with the lens, and retract / collapse it when you don’t, for compactness. This isn’t possible with complex multi-element primes (let alone zooms) but for a long tele like the RF 600mm, where most of the glass is clustered together, in a design with a lot of empty space between groups, it becomes an option.

Retracting design

To unlock the 600mm’s extending mechanism, just turn the collar, and pull (or push) to put the lens into either the extended shooting position, or collapsed storage position. When extended, the lens measures 270mm (10.6 in).

Fixed aperture of F11

Another way of keeping this lens small is its fixed aperture of F11. This is the kind of aperture that traditionally, we would have associated with mirror lenses, which were a devil to work with on D/SLRs because of the dim viewfinder image associated with such a small working aperture.

However, on a mirrorless camera with a decent EVF, that’s much less of a concern, especially now that the Dual Pixel CMOS AF systems in Canon’s EOS R-series cameras can autofocus at working apertures down to F22 (which – not coincidentally – allows for these lenses to be used with the new RF teleconverters). Yes, F11 (and remember that’s fixed – you cannot stop down as there is no multi-bladed iris) is still a limiting aperture for exposure, but it’s a much more practical working aperture now than it would have been back in the days of SLRs.

Image stabilization and autofocus

The 600mm F11 is also equipped with an image stabilization system which can deliver up to 5 stops of stabilization. Canon did not claim an increase in performance when paired with the EOS R5 and R6 IBIS systems, and this makes some sense given the limited ability of IBIS systems to effectively stabilize very long focal lengths. Autofocus is handled by an STM motor, of the kind that has become common in Canon’s more enthusiast-centric lenses and those optics intended to be used for video, as well as stills. It’s not as fast – or usually as silent – as Canon’s Nano USM motors, but still quite effective.

Canon RF 800mm F11 IS STM

The RF 800mm F11 IS STM is a very similar lens to the 600mm, but it’s a little bigger, a little heavier and features a little more glass (11 elements in eight groups, as opposed to ten elements in seven groups for the 600mm).

Bigger and heavier (but still compact)

The 800mm is 35% heavier than the 600mm, weighing in at 1260 g (2.77 lbs). At 282mm (11.1 in) when stowed in its collapsed position, it’s about the same length as the 600mm is when extended. When the 800mm is extended to its shooting position, overall length increases to 352mm (13.8 in). That’s longer than a mirror lens would be, but very compact for a conventional 800mm.

Larger filter ring, longer minimum focus

The general ‘upsizing’ of the 800mm compared to the 600mm extends to the filter ring, which is a less traditional (and less convenient) 95mm. The IS system in the 800mm is only rated to four stops, too, compared to five in the 600mm (rated as per CIPA, measured on an EOS R body). The minimum focus distance is longer, too, at 6m compared to 4.5m.

All of this probably makes the 600mm slightly more practical for most photographers, but there’s no doubt that 800mm can itch some places that 600mm can’t quite scratch. We suspect that both lenses will be a hit with fans of bird photography.

The RF600mm F11 IS STM and RF800mm F11 IS STM lenses are scheduled to be available at the end of July 2020 for an estimated retail price of $ 699.99 and $ 899.99, respectively.

It’s no secret that Sony aspires to dominate in the pro sports photography market, and this new stabilized 600mm F4 is about as professional as it gets. It’s well-built, fast-to-focus, weather-sealed and lighter than any other 600mm in its class (albeit barely).

While 600mm may not be a focal length we shoot at very often, we definitely walked away impressed after putting it through its paces at a Sony-sponsored event.

Hands-on with new Sony FE 600mm F4 GM OSS and FE 200-600mm F5.6-6.3 G OSS

12 Jun

Hands-on with new Sony telephoto lenses

Sony has just released two new lenses, aimed at sports and wildlife photographers. The FE 200-600mm F5.6-6.3 G OSS is aimed squarely at enthusiast and semi-pro users, while the FE 600mm F4 GM OSS joins the FE 400mm F2.8 GM at the top of Sony’s professional lens lineup. We were given the opportunity to shoot with both lenses recently at a Sony event in New Jersey – click through for some initial impressions, and more information.

Sony FE 200-600mm F5.6-6.3 G OSS

The FE 200-600mm F5.6-6.3 G OSS is aimed at enthusiast and semi-professional photographers, especially fans of wildlife and sports shooting. As well as full-frame cameras, Sony expects some buyers to pair this lens with the company’s range of APS-C models, at which point it covers an equivalent focal range of 300-900mm.

One of the selling points of the 200-600mm compared to other lenses of its kind is an internal zoom design, which means that the lens doesn’t get any larger when zoomed through its focal length range. This has advantages when it comes to balancing the lens for handheld shooting, and also reduces the risk of dust and grit being sucked in during zooming.

The G 200-600mm is equipped with optical stabilization, controllable in 3 modes. Mode 1 is standard, suitable for general photography. Mode 2 is specifically for panning, and according to Sony, Mode 3 provides ‘optimum stabilization for dynamic sports action’.

This shot also shows the main OSS on/off switch, and the 3-position focus limiter, which helps reduce unwanted lens hunting in situations where you can safely keep the lens within a certain focus range (i.e., capturing birds at a feeder, or aircraft at close to infinity).

The 200-600mm’s minimum focus distance is 2.4m (~8 feet). This might not seem impressive, but it’s in the same ballpark as other lenses of this type from competitive manufacturers. Autofocus is driven by a linear direct drive SSM motor, which in our time with the lens provides very fast and near-silent AF in normal lighting situations (tested on an a9).

Optical construction of the 200-600mm comprises 24 elements in 17 groups, with one aspherical lens and five ED elements. An 11-bladed aperture ensures circular bokeh even as you stop down modestly, an advantage this lens has over its 9-blade counterparts from competitors. Without the tripod foot attached, the lens weighs 2.1 kg (4.6 lb) which is very slightly heavier than competitive lenses from the likes of Nikon, Sigma and Tamron.

Here’s that tripod foot, which can be quickly unscrewed and detached for handheld shooting, or stowage.

A large, deep hood is provided to help protect the front element from flare (and rain). While the G-series aren’t guaranteed to offer quite the same resistance to the elements as the more expensive G Master lenses, the 200-600mm is extensively weather sealed.

The G 200-600mm F5.6-6.3 will be available in August, for $ 2,000.

Sony FE 600mm F4 GM OSS

The FE 600mm F4 GM OSS is aimed at professional photographers, and joins the FE 400mm F2.8 GM OSS at the very top of Sony’s lens lineup, offering the best optical technologies that the company is capable of creating. Sony’s G Master series is designed according to the principle of ‘no compromise’ and we’re told that when it comes to autofocus speed, the FE 600mm F4 should be able to keep up with the autofocus speeds of future generations of Alpha-series interchangeable lens cameras. Put simply, the lens is capable of even faster autofocus communications and speeds than are currently possible with the company’s flagship a9 camera.

Offering an equivalent focal length of 900mm on APS-C, the 600mm F4 can be used on all Sony E-mount cameras, and has been designed to work with Sony’s 1.4X and 2X teleconverters without a significant penalty to either AF speed or sharpness.

Hands-on with new Sony GM 600mm F4 and G 200-600mm F5.6-6.3

The GM 600mm F4 is the smallest and lightest lens of its kind currently on the market – just edging out the Canon EF 600mm F4 III at 3,040g (6.7 lb) compared to 3,050g. Like the GM 400mm F2.8, the weight of the lens is mostly concentrated towards the rear, which means that despite its size, the lens can be hand-held for short periods of time without being unmanageable. The lightweight construction is partly achieved thanks to the extensive use of magnesium alloy in the body shell.

Despite its relatively light weight, the 600mm F4 has a complex optical construction, made up of 24 elements in 18 groups, including a 40.5mm drop-in filter. This is compared to 17 elements in 13 groups from Canon’s EF 600mm F4 III. Of these 24 elements, three are fluorite, and two are ED glass. Just like the 200-600mm, the 600mm F4 features an 11-bladed aperture, meaning it can retain circular bokeh as you stop down better than its 9-bladed competitors.

The GM 600mm F4 is intended to be used alongside the GM 400mm F2.8. As such, all of the major controls are identical, and can be found in the same places. This is to ensure that life is as easy as possible for a photographer swapping between them at (say) a sporting event. Even the focus rings of the two lenses are the same size and the same distance away from the camera body.

This view also shows the tripod foot tensioning screw, and a dedicated strap lug. While the weight of the 600mm F4 can probably be supported by the lens-mount of an Alpha-series camera for short periods of time, this is not advisable. The rotating tripod ring can be ‘declicked’ if required, and a security wire can be connected to a dedicated socket in the foot (not pictured) to secure it against theft.

Hands-on with new Sony GM 600mm F4 and G 200-600mm F5.6-6.3

The GM 600mm F4 has a minimum focus distance of 4.5m (14.7 ft) which is slightly longer than the 4.2m (13.7 ft) minimum focus of its nearest competitor, Canon’s EF 600mm F4 III.

Autofocus throughout the 600mm F4’s focus range is swift and accurate (tested on an a9), thanks to dual XD linear motors, similar to the ones found in the 400mm F2.8. These provide the power required to drive the relatively large, heavy focusing group across its range extremely quickly. In the relatively low light of an artificially-lit sports arena, the 600mm performed very well in our limited testing, even when paired with a 1.4X teleconverter.

Here’s the 40.5mm drop-in filter, which is an integral part of the lens’ optical makeup. The filter size is the same in both the GM 600mm F4 and the GM 400mm F2.8.

Hands-on with new Sony GM 600mm F4 and G 200-600mm F5.6-6.3

This view shows (R-L) the wide and deep focus ring, the ‘adjustment ring’ and one of the four focus hold buttons which are standard on professional lenses of this kind. The adjustment ring is effectively a ‘nudge’ control which can be customized to perform various actions, one of the most useful for sports photographers being a ‘focus position recall’, to quickly jump to a preset ‘home’ focus position of your choosing.

The Sony FE 600mm F4 GM OSS will be available in August for $ 13,000.

05 Sep

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_8118953092″,”galleryId”:”8118953092″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Amid its full-frame mirrorless announcements, Canon has also made room for some L-series lens updates. Canon has focused on reducing weight and so its EF 400mm F2.8L IS III USM and EF 600mm F4L IS III USM both lay claim to the title of “world’s lightest” in their respective focal lengths. The 400mm F2.8 has shed 1kg / 2.2lb and the 600mm F4 is 0.86kg / 1.9lb lighter. Both lenses feature advanced coatings, improved image stabilization and circular nine-blade apertures.

The Canon EF 400mm F2.8L IS III USM will sell for $ 12,000 and the Canon EF 600mm F4L IS III USM is priced at $ 13,000. Both lenses will ship in December 2018.

Press release

Canon Redesigns Premium L-Series Super-Telephoto Lenses With Its New EF 400MM F/2.8L IS III USM AND EF 600MM F/4L IS III USM Lenses

New Compact and Lightweight EF Super-Telephoto Lenses Are Well Suited for a Variety of Photographers’ Needs

MELVILLE, N.Y., September 5, 2018 – Most professional photographers need to carry multiple lenses in their camera bags. Helping to lighten their load, Canon U.S.A. Inc., a leader in digital imaging solutions, introduces two new super-telephoto lenses, the EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM. Both lenses possess a dramatic weight reduction and high-image quality, making it ideal for shooters to easily transport and capture images during action-driven scenarios, such as sports and wildlife. Both lenses now hold the title of world’s lightest in their respective focal length*. The weight of the EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM lenses has been reduced by 2.2 lbs. (more than 25 percent) and 1.9 lbs. (more than 20 percent) respectively.

“When developing updates to some of Canon’s most popular legacy lenses, one common question that is asked by photographers was ‘can they be lighter,’” said Kazuto Ogawa, president and chief operating officer, Canon U.S.A., Inc. “The significant reduction of weight in these two lenses addresses this customer need and delivers thoughtfully designed, high-quality optics .”

The new lenses are must-haves for advanced and professional photographers shooting wildlife, aviation, sports and news with Canon’s new EOS R full-frame mirrorless camera (with use of one of the three new Canon mount adapters), as well the EOS 1D and 5D series of DSLR Cameras. Both lenses feature two of Canon’s most advanced propriety lens technologies – Air Sphere Coating (ASC) and Super Spectra Coating (SSC), helping to reduce flaring and ghosting, and suppressing the reflection of light, leading to vivid images. These updated lenses inherit the excellent overall build-quality and ruggedness photographers have come to expect and admire from the Canon EF L series of lenses. In addition, the minimum focusing distance has been improved for both lenses, from 2.7m to 2.5m (8.8ft to 8.2ft) for the EF 400mm f/2.8L IS III USM and 4.5m to 4.2m (14.8ft to 13.8ft) for the EF 600mm f/4L IS III USM.

Additional noteworthy features of the lenses include:

  • Upgraded Optical Image Stabilization from three-and-a-half stops to five shutter speed stops1 of correction over the previous f/2.8 lens
  • Improved, flexible focus control with a customizable electronic-focus ring
  • Two fluorite lenses and one super UD lens, helping to provide high image quality
  • Circular nine-blade aperture
  • 17 lens elements in 13 groups
  • Heat-shielding paint helps prevent lens temperature from rising during excessive exposure to sun
  • Fluorine coating on front and rear optical elements, helps to reduce smears and fingerprints
  • Inner focusing system with Ring Ultrasonic Motor

Availability and Pricing

The Canon EF 400mm f/2.8L IS III USM is scheduled to begin shipping in December 2018 with an estimated retail price of $ 11,999. The Canon EF 600mm f/4L IS III USM is scheduled to begin shipping in December 2018 for an estimated retail price of $ 12,999^.
