One of the best Canon EF Zoom lenses ever offered.
The 100-400ii EF L is an extremely fast focusing and very sharp lens what works well with my Canon R5ii. It also remains sharp with the Canon 1.4 EF II extender. It's a bit heavier than the newer 100-500 RF L lens but the build quality of the EF lens is top tier and with the extender, the 100-400 EFii allows for the full range of zoom where the 100-500 RF lens with the ...

Versatile glass
Capable lens in so many ways. Transition to mirrorless bodies is seamless. From Airshows, birding, and Solar Eclipse this is an amazing tools.

The Fourth Lens in the Trinity
This lens was purchased as the alternative to an EF 600mm f/4L IS USM used for birds and wildlife. Obviously, the 600mm isn’t suited to walking around, or keeping on hand for opportunistic shots.
The build quality is excellent. It is a rugged lens and while it is not light, it is the extensive glass and the metal body adding that weight so there’s real benefit to that ...

Great 100-400mm lens, sharp and quick.
Sharp, easy to use lens. Compact and not too heavy. Sharp at all focal lengths too. I enjoyed this lens a LOT.

Great Versatility. Perfect for Outdoors
I bought this intentionally for an airshow and it's quickly become one of my primary lenses. Never leave home without it.

Lens For All Reasons
Came up for a fair price used, so I took a flyer. Own an incredibly sharp 400mm f4 DO, so telephoto was pretty much covered. Also have the 180mm Macro, which is a standout lens.
This lens covers both ends and what's in between, and does it with high contrast, high resolution, and tolerable weight. Certainly much less than carrying both the others into the field. ...

Outstanding photography is easy with this lens.
I purchased my lens in 2015 and have been using it since. I've taken hand-held photographs where object I wanted to get was moving fast. The lens locked on in most instances, allowing me to get photos that would not be possible using other lenses.

Great telephoto lens!
Don’t regret the purchase of this beauty! Hasn’t let me down yet. I’m used to the weight now and most of the time don’t even use a tripod. Use it on my 5d mark IV as well as my 80D when I want that extra 1.6x’s reach. I use it for moon and sun photography as well as wildlife. Highly recommended!

Received and used new lens.
I have received the lens and like it very much. I look forward to using it, especially this winter. Even though it was out of stock when I ordered it, got it reasonably quick. Thank you.

Worth the money and great investment!!!!
Bought this lens last summer and have added Extender EF 2x III for long distance shots. The focus ring is so great and can focus more efficiently and quickly when going for any motion shots. I love the quality of the pictures, and how well this lens works for distance. Pictures will show you the quality of what you are purchasing from Canon.

Wicked Sharp
Works great on all my cameras, but for the most reach and most pixels in the subject, my M6 is the champ. I can set it up looking across the apex at a race track and crop to 50% and read the small print the stickers. Then I can shoot pan shots of the cars with my 7D/EF 55-250.
