Canon EF 100-400mm f/4.5-5.6 IS USM 'L' 'ii' lens review with samples (Full-frame and APS-C)

I struggled with this lens initially and eventually discovered that the only fault was ME. I have made my peace with this lens and Yes, Indeed this is a great lens.Work within it's parameters and you won't lose. I am coming from Nikon FE2 prime lens and fixed ISO perspective. I have had to modify my approach with this lens but I must say when you have gripped it then this lens delivers absolutely astounding results. On full frame I had no problems but on crop sensor I was nonplussed. This was me failing and not the lens. This lens is first rate. Love it.

[@JerryC25]

I got this for an African safari. Killer lens

[@jonno52]

Thanks Chris, excellent review. Unfortunately I bought the first version just six weeks before Canon announced this one. It was acceptable but no more really. I resisted getting the new one for a couple of years, but in the end went for it. Glad I did, the IQ, Image stabilization and AF speed are far better. It's a very fine lens.

[@rickyscorner8091]

No way! The current image quality rubric is much better. The black and white targets do a better job of showing sharpness and CA, the collage of images give a much better idea of the color saturation and contrast. Compare the Canon 70-300 L and non-L lens reviews, and you'll see what I mean. The L lens is cornucopia of resolution and poppy color compared to the other lens. It wouldn't be so obvious with the drab brick wall.

[@BigBad-zg5rh]

Great review. I use this lens on my 1DX MKII and absolutely love it......much easier to carry when on foot than several prime lenses.

[@elizabethdow454]

Thank you so much Christopher! Seriously love your reviews and your honesty!

[@kevindiossi]

This is a seriously stellar lens. I've been using it to shoot motorsports professionally for the past 2 years and it's a lens I can't live without. I rented the 400 f/2.8L IS USM and I honestly ended up enjoying the 100-400 MORE because of its size, weight, and ability to hand hold it. Not to mention, carrying around a lens that is valued at the price of a car makes it hard to enjoy when it was always in the back of my mind. Still, I really love this lens and can't recommend it enough...I think I've personally sold 3 of these to other photographers by talking it up and showing off its capabilities. LOL

[@forsterl.stewart414]

Kevin DiOssi I agree canons flourite glass, the stabilization is fantastic, the close focusing is a bonus and i could go on and on.

As a motorsports shooter, could you give me an idea of how you think this lens would do filming Motocross? I've been between this, 70-300, and a 70-200 but leaning this way. Any thoughts would be great!

Excellent review. Very comprehensive.

[@marramraabe]

Thanks for getting a review out of this amazing lens! My camera bag is full of lenses you had endorsed in previous reviews (Samyang 8mm Fisheye, Canon 10-18mm STM, Samyang 14mm f/2.8, Sigma 17-50mm OS & Canon 55-250mm STM), but this was the first (and by far most expensive) lens I'd pulled the trigger on without hearing your take on it beforehand. This review turned out to be a very satisfying validation for a lens that has proved to be a stellar performer and my workhorse for wildlife, birds and aviation photography. Keep up the awesome work!

[@JoaquimGonsalves]

Can't wait for a comparo with the new Sigma 100-400. :)

[@ferdigrafie]

[@Ihuben]

Me too!

[@joelmspencer]

There is a comparison of the two lenses, basically for still photography where movement isn't important the Sigma is better optically, but as an allrounder the Canon is better and far far superior in AF and build quality. I should also say that whilst the Sigma is optically better it is fractional at most apertures and focal distances.

[@matthewaugsburger536]

Joel Spencer with a full frame camera you are right but once you go apsc the canon beats out the sigma

[@richardpcrowe]

I shoot with both Canon full and crop frame and Sony APSC cameras. I did not want to purchase a second 100-400mm lens for the Sony system. IMO, neither the Sigma MC-11 nor the Metabones IV adapters worked up to my standards in adapting long focal length Canon lenses to Sony E-mount cameras. However the Viltrox Mark-2, Canon to E-mount focal reducer seems to work just fine with my Sony A6400. Even the IS works efficiently. I can hand hold the camera/lens at 400mm using 1/40 second and get sharp imagery. Focusing is accurate and relatively fast. I switched the OEM tripod ring for a Kirk replacement. The advantage of the Kirk Tripod ring is that the foot is grooved for an Arca Compatible clamp so I don't need an accessory clamp. I don't know why Canon and Sony can't groove their tripod ring feet for Arca Compatibility - after all, Tamron does. It certainly would not add much to the production costs of any lens. I tried to get a metal shop to groove the OEM foot but I was told that the OEM foot was cast aluminum and could not be grooved. If the foot was made of milled aluminum, I could have had it grooved for an Arca Compatible clamp... As far as performance on either the full frame Canon 6D2 or the APSC 7D2; this lens is an absolute dream! I LOVE IT and I am happy that I can use it with my Sony system...

[@adude394]

Here's me, late to the dance as usual. My new (used) 100-400 just showed up today, and I immediately put it on my 1DX Mk III and took a walk at lunchtime and took a few shots. On first blush, it is quite a step up from the Sigma 100-400 that I traded in. Looking forward to trying it on my 7D Mk II as well.

[@RFGfotografie]

Truly the best lens ever made!

Since buying this lens my 70-200 F2.8 rarely gets used. I'm seriously impressed. Fortunately I don't need to use it in low light. But I have a wide angle 2.8 which covers that in terms of my photography

Would love to see some of these canon lenses tested on your A6300 with the Sigma MC-11/Metabones. Especially the telephoto options. I think others would too.

[@ytytytyt01]

Nice review, as I thought it would be! I used to have the 400mm prime, but sold it so I could get this (I was missing the flexibility of being able to zoom). It's the best decision I ever made and I'm so happy with it! I shoot mainly wildlife and birds in flight . . . . it's a great lens! By the way, it was fantastic to see some photos of Llangrannog and Mwnt. We go there every year for a holiday :)

Great review and sounds like my next lens. I previously owned Canon`s 70-300mm L lens, and used it on my 7D with superb results, and this one sounds like a carbon copy in all respects. Its a lot more expensive and much bigger, but the extra reach is most welcome for wildlife pics, and being able to use Canons extenders is a big plus.

[@artem.boldariev]

Hello Christopher! Firstly, thank you for your reviews. It is due to them I am now a happy owner of Canon M6 II, as well as EF-M 32mm STM, EF-S 55-250 IS STM as well as EF-S 17-55mm IS USM. I think that at some point I will want to take a look for a long range zoom lens (for birding/wildlife). However, I am not sure at which one I am going to aim. There is this one (Canon EF 100-400mm f/4.5-5.6 IS USM 'L' 'ii' ), as well as Sigma 150-600mm Contemporary. As a Canon M6 II owner, I know that the sensor is very demanding. So as you own/owned Canon M6 II as well as the Sigmal lens - what can you say on the topic?

[@roseedfleming6332]

Christopher thanks for the review of the 100-400mm are you going to do a review on the new Canon 70-300 ii I think that it is more in my price range.

Considering this lens at the moment, great review Chris, thank you :)

[@TheLordstrider]

Christopher, i know your not answering my comments for many years but please i only have one question. I am thinking to upgrade my Canon ef 400mm f5.6 L lens that you reviewed to a canon ef 100-400mm F4.5-5.6 L Mark ii lens. all i care about is the sharpness (to get more keepers shots the i guess will help also) which one of those two sharper? i would have not troubled you with this question if you had the same tests for both lenses. (tests changed from the door to charts) hopefully you will find a spare minute for a simple answer. either way, thank you for your work. i am watching your videos from the day you started this channel and it helped me very much.

[@hattrickster33]

I chose the 300 f4 IS with a the 1.4x teleconverter over this. It was a hard choice but I couldn't justify the difference in price, especially since I just needed 400mm and not a zoom. You effectively get a 400m (~420mm) f5.6, with a bit lower IQ than the 100-400 II. If you want a zoom though, the 100-400 II is obviously a much better choice. And it has somewhat better IS.

thanks for the great review, how does this compares against sigma/tamron 150-600mm in sharpness, focus and useability if budget is no issue?

I've only tried the older Tamron 150-600

[@alexbarnett8759]

They are terrible

[@stevesharkey3312]

I have the Sigma 150-600 contemporary lens already, to get this lens I’d really be pulling out all the stops (I’ve only bought 4 cars that have been more expensive than this!) do you think I’d be better off investing more time in using my Sigma and forgetting this (for the moment)? I was shooting at a motorsport circuit and to be honest whilst the Sigma was great for shots down the pit lane and of the driver in the garage during an in-car briefing it was too much for on track action at 600mm and over the top size, weight & aperture for 200-400mm shooting.

[@Christoph_Schoetschel]

Hey Christopher, great review, as always. I have one question: Did you find it to be sharper than the 400mm 5.6 L as it is a prime or do you prefer this one for image quality (not counting the zoom ability)? Thanks and greetings from Germany

[@christopherfrost]

Hmm. I think it's probably just as sharp as the 400mm prime. It is amazingly sharp

[@HMNTMYR]

You are suggesting that the 2x converter will work. I find that you can only use the 1.4 iii and 5D iii and still be able to auto focus And even then you are limited to center metering plus 4 surrounding points. Even the 1.4 iii combo on the 6D is a no go. ( your experience with the other newer cameras my vary.

[@lmallard3788]

At what aperture, with this lens on a 24 mp camera like 80d, 77d, or t7i would diffraction become too limiting? I think my 80d is diffraction limiting at f/5.9. I dont know how bad the diffraction is beyond f/6, because I have not found a chart. But the DLA of my 80d, has made me nervous about buying any L series lens slower than f/2.8. Thanks for any additional help. I have gotten a lot of help from your video and I thank you for doing them.

[@christopherfrost]

On a 24mp APS-C camera, diffraction on nearly all lenses can become very slightly noticeable at f/8, a bit more noticeable at f/11, and very much so at f/16

Hi Christopher - great videos ! I currently have a Sigma 150-600mm C being used on a Canon 7D Mkii - I am considering losing some reach with the 150-600mm, and buying the Canon 100-400 instead. Although my trusty Sigma has served me well for my wildlife photography, I wanted to know if you thought there would be any merit in me spending the money in swapping my 150-600 for the 100-400?....is the price difference REALLY worth it, or are the improvements (if any) only marginal? Thanks again for the great reviews...many of my lens choices have come from viewing your channel :)

[@christopherfrost]

I would personally keep the 150-600 just for the extra reach

[@teej626]

I've used both the 150-600C an currently own the 100-400L II. The 100-400 blows the Sigma away. Even cropping the Canon to 600, the results are significantly better, IMO. Also, the Canon is easier to use hand held. This is just my own personal opinion from using both lenses, but I do not regret one bit buying the 100-400L II. It's an amazing lens.

This sounds like a great lens, except for the pronounced focus breathing I've heard about. Turns this lens into a real 350 mm-370 mm true focal range. Limits birding even with a APC camera. Question the teleconverters. Heard a lot of mixed reviews about that. Any insights I would welcome.

Christopher, my wife and I enjoy and appreciate your thoughtful, well done reviews. I know you've reviewed the Canon prime 400 f/5.6 quite some time ago. Wanted to ask you, or anyone else here who has tested or owned both this 100-400 and the prime, which lens was sharpest? I have heard that both are as sharp as one another. I am thinking of selling my Sigma 150-600 C and the Canon 400 prime if the 100-400 mkII is at least the same sharpness. The Sigma just doesn't get used much, even though I have got some fantastic images from it the few times used. I hit a speed bump in life and lost feeling in left hand (stroke) not long after having purchased that big ol' Sigma. I can handle that prime still just fine, but often wonder if I'd get more very sharp 'keepers' with the image stabilized zoom. Anyway, appreciate any replies in advance. And keep up the fantastic reviews Christopher. We respect your opinion/reviews very much. All the every best to you and your Bride there. She's a pretty young lady. You came up Chris.. hehe..

This Lens on the M6 ii, what you think about?

[@Technologyadvisor1]

Hello Chris I noticed your review was simular to my review I did 2 years ago when I got this lens. The problem I noticed was auto focus was very slow and as seen in your video it confirms this. Many people say the auto focus is very fast but looking at your test at 400mm auto focus is very slow. When I tested this lens I used a 7D and 600D and focus was slow since my test I watched a video of the 1DX on this lens and it appeared the focus was 3 times faster it does seem to me canon is making a big mistake here. On the newer cameras the focus is many times faster than on older cameras. Were you able to test the lens on the 7DII and or maybe compare focus speed with an older camera such as the original 7D or 60D. I believe the m3 you used to do your aps-c test uses an adapter and the m3 has a smaller battery so your test is floored. Did you try the 70D on this lens? I have gained alot of criticism on my review of the 100-400mm L II lens but my focus tests were very slow as soon as I tested the sigma 150-600 I found focus speed many times faster than the canon L lens. Please let m know what you found out I am thinking about getting the lens again and testing it with a 80D to find out if the old vs new camera is the issue here on focus speed.

It worked nice and fast on my 6D :-)

Can this lens be attached on my canon t7i APSC- sensor without any mount?

[@teej626]

It will mount directly to your camera.

Is it worth it to go from a 70-300L to this?

[@abhirammanoj8910]

Can we use this lens in canon 1500d

Thanks for another excellent review.
