Truly a beast of lens with outstanding build quality, wide 2.8 aperture, fast autofocusing, light weight relatively speaking for its size, and superb image quality. I like to shoot wildlife early in the morning, and decided the 400mm 2.8 would suit my needs better. If I need more reach, the Extender RF 1.4x paired with this lens is also amazing, making it a 560mm F4.

Amazing bokeh and lightning-fast autofocus with the R5.I also use it with the RF 1.4x and notice no loss of focus speed or sharpness.

Quite the lens. It focuses quickly, is great in low light and takes a nice image. The lens hood is rather long and is difficult to use in a smaller car when using the car as a mobile blind. Canon does make a shorter lens hood but the price is ridiculous. I am quite pleased with the lens overall. It all performs well with both a 1.4 and a 2X entender.
In life there are things that are expensive and there are things that are valuable. This lens is a luxury item, no question. But it performs so well for low light sports and other important situations. I love the light weight and performance of the AF. If you're in the market for this lens, you won't regret it.
Bought this about a month ago and this lens is take sharp. Con: it’s a bit heavy for someone in my old age to hand-hold this beast, but I still love this beauty.
I worried 600 mm.But I wanted the light lens. If my occasion is 400mm, the child's athletic meet photography is also possible.There are no bought budgets, so the substitute which is 400 mm of 600 mm in +RF1.4x.When wanting 800 mm, I take a picture of 400 mm by 1.6 times of +RF1.4x and crop mode.I'm taking a picture in EOSR6 now, but so 7,700,000 picture elements of crop mode is in the light room and strengthens it and gives a picture element.Which is changed for R3.I wanted 45,000,000 picture elements, so R3 is regrettable. Essential best as well as matter of coming out.I'm not good at English by Japanese and a PC is being translated, but I'll trust whether the written contents can be understood.I thank B&H for usual politeness which is under care for a long time.
it's been almost a year since I bought this. It is worth every penny; I have used for sport and images are jaw dropping. I have even taken it for astrophotography! yes Astro! for deep sky images, the far galaxies are tack sharp. I took to the zoo and will be taking on Safari next week. It is lighter than you might expect a lens this size to be, it can be handheld (not for long) but it can be. It is a luxury item as said in other reviews. But once you get it, you realize it is a necessity for great images. Love, love, love it! Thank you canon!
I just received my lens a week ago. I love the lens. My photos are very sharp. Well worth it.
Over the years, I have taken tens of thousands of images with the Canon prime lenses. Various versions of the 600 as well as the 800 and the 400 DO. This lens is perhaps the best glass yet. However, I have only used it with the R5 and am now mirrorless only. My perception is that my last mirrored Canon 1DX Mk III may have been a better camera.
