I have this lens and it pairs perfectly with my 5D4. Great combo for wildlife. You get amazing subject separation at F4 and is very useful in lower light situations where I found that the 100-400ii 5.6 would struggle a bit.

Ohh man... you are the best lens dude :) Keep up the work, Love your revs...

Thank you! Please do 400mm f2.8 iii

An interesting comparison would be to test the 300mm f2.8 IS. Either version. This has a reputation of being Canon's sharpest lens. The II version is only slightly heavier than the 400mm f4 DO II, and with a 1.4x extender creates a 420mm f4. The prices are similar for the 2 lenses and the 300mm f2.8 lenses have a reputation of being very sharp with teleconverters. I suspect that the 400mm DO might just be a tiny bit sharper than the 300mm f2.8 IS II with the the 1.4x extender, and the AF a bit faster - but not the bare 300mm f2.8 without the 1.4x extender. But I doubt there would be much in it, and the 300mm f2.8 would be more versatile, because of course it is also a 300mm f2.8.

Anybody else press the like button and then watch Christopher’s video because you already know it’s going to be great?

Adding this to my Christmas list.

Finally a Canon video! Nice one btw :)

Thank you for doing more expensive lenses. Can you also test them with the tele converters attached? Thanks 😊

I own, and Loooove this lens. It's so small and light vs a 400mm f2.8.

Tbh, I had no idea that those lenses existed before this but they seem way too niche to be introduced this early on for the RF mount. f/11 makes them pretty worthless for a lot of applications that demand conventional super-telephoto optics (why not just get a cheap mirror lens at that point) and not many entry-level buyers need a super-telephoto. I'd have much rather preferred to see Canon release an updated 400/2.8, 600/4.0, 800/5.6, or better yet, a more affordable 50mm optic to replace their super old EF 50/1.4 or EF 50/1.8 which is quickly becoming irrelevant.

If you like this lens, Nikon makes a Phase Fresnel (diffractive) 300mm f/4 that’s super sweet, you should test it on the Z7. It’s amazingly compact, the size of a 24-70, and a lot more affordable than this, though still quite expensive

Another great video one thing I would like to see you do is a comparison of a crop camera with a lens like this verses a full frame with the same lens but with a 1.4x tele converter in place to bring the image magnification to around the same as the crop and then the full frame without the 1.4x and images cropped down to around the same to see what works out best 👍👍👍

I own an Ai-S 400mm f2.8 at 5.2KG and is manual focus which makes it difficult to hand hold and focus but is possible. I love old manual lenses but would love a Nikon 400mm f4 with autofocus.

The DO can sometimes yield some rather nervous bokeh for certain backgrounds. It doesn’t happen often for me, but it does happen from time to time. It would be easy to miss this if you only use the lens for a short time.

@kirostar12

I have a Canon 400mm F5.6 and this lens is little bit sharper then 400mm F4 DO IS II but is almost not noticeable is my opinion. I upgraded to 400mm F4 DO IS II to take advantage of the greater magnification I can achieve.. With 1.4 TC = 560mm F5.6 or 896mm with 1.6x crop body. That's help with the AF performance at that magnification specially for birds in fly. Also I can quickly back the lens to F4 when I need more light just before sunset, around sunrise or in a cloudy day. 800mm F8 or 1280mm in 1.6x crop camera is possible in a sunny days for stationary objects. The ability to have 4 stops IS is something where the 400mm F5.6 doesn't have. I can shoot handheld in slow shutter speed and eliminate the need of tripod. I am really happy I found this amazing lens for just $4650 on E-bay in Mint condition and I even was able to lower the price to $4000 :). In conclusion, I can say that I have been shooting wildlife for more than 10 years, I have tried almost all super telephoto lenses and I can say that this is one of the best lenses for shooting wildlife, which makes your work enjoyable and easy.

The canon 135mm f2.0 L has been good to me for M6 II would be nice to see list of zooms that work well with it since its so demanding as you said.

if you only into photos with not to much sport and no video, i would suggest going the pentax way, i started with a canon 80D and now i bought a Pentax K1 on grey market. They sell for very cheap for what it is : 36 megapixels on full frame, you have an outstanding quality and so many functions you dont have on other brands like astrotracer. I never regret switching from canon to pentax

My DO is very sharp on my 90D, so I am wondering if something is off with your copy. I have also used it a lot on a range of other bodies from the 7D mark 2, the 5DSR, and now the R5. Of course, the 90D has the highest pixel density. I have also used my 90D and the DO with a 1.4X teleconverter as well, and excellent sharpness was the result.

For such a lens I think you can skip the usual weight & size/controls & functions/build quality/AF/sharpness & CA/distortion/focus breathing/close focus/bokeh/LOCA/bright spot sections, and put more stress on the pricing 'cos that's all we care about!!!

It's funny when Canon creates such similar tech to Nikon, and then charges twice as much....

It's not designed for macro photo work. This test is foolish like anyone using this type of test . Try the lens in a real world situation. Even on the 90d or the 5dsr the lens rules. It is among Canon's sharpest lenses of all; the only lenses slightly sharper may be some of the other $10,000 ultra teles, otherwise this 400mm is sharper than any of Canon's black lenses, sharper than any of its zooms and sharper than any of its macro lenses. Although the 400mm DO is not an L lens. Canon claims DO lenses are all that L lenses are, and then some. No big deal; this lens has enough alphabet soup as it is. No other lens or camera manufacturer has produced anything like the Canon DO lenses. They're not smart enough to figure out how Canon did it. And you're not smart enough to test any lens.
