Canon EF 400mm f/2.8L IS III USM Overview

Pairing a favored super telephoto focal length with a bright f/2.8 maximum aperture, the EF 400mm f/2.8L IS III USM is a Canon L-series optic well-suited for outdoor, wildlife, and sports applications. This version III of this prized lens features a lighter weight design along with a sophisticated optical layout and updated handling capabilities. The fast maximum aperture enables extensive control over depth of field for isolating subjects using selective focus, and it also benefits working in difficult lighting conditions. Both Super UD and fluorite elements are used in the optical design to help reduce color fringing and chromatic aberrations for high clarity and color accuracy, and Super Spectra and Air Sphere Coatings have been applied to individual elements to suppress flare and ghosting for increased contrast and color neutrality when working in backlit conditions.

Beyond the optical attributes, this 400mm f/2.8 is also characterized by its advanced five stop-effective Image Stabilizer system, which has three separate stabilization modes to suit various shooting applications. Also complementing handling is a sophisticated ring-type USM, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override. A customizable electronic focusing ring further contributes to precise manual focus control, by affording three focusing sensitivity levels for different applications. Additionally, this lens is weather-sealed for use in trying environmental conditions, and it has a removable rotating tripod collar to benefit working atop a tripod or monopod.

Super telephoto prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 640mm equivalent focal length.
Fast f/2.8 maximum aperture benefits working in low-light conditions and also affords significant control over depth of field for working with selective focus techniques.
Super UD and fluorite elements are used to greatly reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.
Super Spectra and Air Sphere Coatings have been applied to individual elements to control lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to five shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure.
A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
Customizable electronic focusing ring provides three sensitivity levels for how quickly and precisely the lens can manually focus.
Focus Preset function is available to quickly recall a programmed focusing position.
Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions and also features a fluorine coating on the front and rear elements to guard against water spots, smudges, or oil residue.
Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.
Compatible with optional EF 1.4X and EF 2X teleconverters.

Canon EF 400mm f/2.8L IS III USM Reviews

Amazing

Was surprised at how light this lens is compared to the previous version. Same great quality and fast focusing.

Amazing lens!

I do a lot of HS football photos and worried that with the 400mm I may be a little to close to the action. It took me a little bit of getting use to but once I figured out my standing points on the field I have got nothing but amazing shots with this lens. I shoot with a 1DX MarkII. This is a great combination. Beautiful color, sharp and fast! If you can afford it I recommend it. I was debating between this and the 300mm 2.8 and believe I would have been happy with the 300mm but am very happy I bought the 400mm.

Most wonderful lens in the universe

I sold all my video gear and still fell short of the full amount of this crazy expensive lens. But OMG, is it worth it. The auto focus and stabilization when handholding is quick. When I get it in focus, it's super tack sharp with lots of contrast: in EOS Utility, some of the deepest blacks are crushed compared to what my other Canon & Zeiss lenses would register. As far as weight, it's not heavy, especially for its size, but it's still hard for me to hold for very long (wimpy gal). I haven't tried it on a tripod but I can imagine it'll be even more amazing. I had read that using a 400mm is also great for landscapes so that will be worth exploring. Being a widow, I can say with conviction that life is very short -- and that this lens is an exciting purchase that will bring me some moments of joy for many years to come.

Worlds of Difference from Version II

I am writing this review for both he 400mm f/2.8 IS III & 600mm f/4.0 IS III. I had the opportunity to test the 400mm, 600mm, 500mm f/4.0 II, 200-400mm f/4.0, and had my own 300mm f/2.8 IS II. These are the things that deserve highlighting: (1) Weight: The 400 and 600 are lighter than any of the lenses. The 200-400 is by far the heaviest. (2) Balance: Both the 400 and 600 have the best center balance. (3) Focus: The 400 and 600 provided the fastest auto focus. (4) Image Quality: This is hard to explain unless you place the images side by side with the 400 or 600. The 400 and 600 performed miraculously, even in low lighting for a sport venue. I had no intention, nor was I looking to purchase a new lens. Up to this point, my plan was to wait for Canon to release an updated 200-400mm zoom. I've used the 200-400mm lens in the past and absolutely loved it, but some of the sporting venues experienced low lighting once the sunset and the 200-400mm did not perform well. Now, I'm in a dilemma. I've been saving money for the new Mac Pro (and monitor) due later this year and I cannot stop thinking about the 400 and 600. As a side note, I installed the Canon 1.4x III extender on the 400mm and found the results came out just as clear. My recommendation, go see one for yourself and if you have a version II, bring it with you so you can see and feel the difference.

Weight difference is HUGE!

By Paul

I used the Ver II for 5 years with great success.  I loved that lens with exception of the weight.  I am 64 years old and hand hold frequently and the weight was starting to be a burden. I decided the 2.2 lb. reduction would be a huge help with the Ver III so I purchased one.  But, the lens feels MUCH lighter due to the movement in the weight  location.  The new lens has so much weight removed from the front that it makes a huge difference in the way the lens feels.  Lots of weight in the front also gives lots of inertia and difficulty tracking.  The Ver III with its weight in the middle of the lens cures this issue and the lens feels much more maneuverable for tracking Also when the weight is in the front (Ver II) and your arm is supporting the lens at the end, it really makes your arm sore.  The Ver III with its weight rearward is easier to support since the weight is closer to your body. So, from the weight standpoint, in many ways, the Ver III is a huge improvement. From the performance standpoint I feel the picture quality is the same but I need more time with it.  The focusing is rocket fast and accurate. The price of this lens is staggering.  If your pocketbook allows the purchase you will likely have little to complain about t once you have it.  Be warned that at the time of this review, there is a firmware upgrade due to some issues with video. Final comment.....Incredible lens.  No regrets.

Handles like a dream

And I’m a 220 lb 69 year old weakling. I do all hand shooting. It is so light I don’t even realize it is there. Feels like my 14mm lens. Credit the movement and rebalancing of the weight towards the shooter for this.  Takes great pictures. No complaints. Got everything I thought I was getting and more. It is the best you can buy. The f/2.8 and f/3.2 f stops really help especially in low light and on cloudy days.

So much lighter than the previous version. Image quality is great. Works well with the RF converter.

Ideal for hand-held bird ptg on long hikes

By John
Rated 5 out of 5

For bird photography, I need an 800 mm telephoto that I can hand-hold and carry on difficult hikes. With 2x extender, this lens gives superb quality and still can be hand-held. I made it as light as possible by removing the shoe and using my 5D camera body. With hood, the weight is then 9.8 lb. Without hood, it is 9.0 lb. Not easy, but doable -- especially when Birds of paradise are at stake. Excellent combination; happily recommended.
