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.

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 RF extender restricts the zoom range and the full retraction of the lens barrel. I also own the Canon 200-800 RF zoom which I also use for longer range reach. The two lenses provide all I need for long reach subjects.

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.

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.

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 cost.
While the 400mm maximum and f/5.6 limit at that length can’t match it, the performance of the 100-400mm is more than adequate for the settings and conditions it does fit. I was afraid I would be compromising on IQ but that fear quickly vanished as I found that at any focal length this lens can produce razor sharp, high contrast shots I am happy to call my work.
The usability is top notch as well. The AF is fast, not quite as fast as the EF 70-200mm f/2.8L IS USM but close. I rarely have a problem getting good focus, and in time to get the shot. The image stabilization is excellent as well, and with three modes, including one that stabilizes only at the moment of shooting, it doesn’t interfere with getting the shot with dynamic, moving subjects like birds in flight.
With the barrel retracted and the hood inverted it presents a surprisingly compact package making it easy to carry and even with the hood in shooting position if it is zoomed to 100mm it can easily be carried on a strap while walking or hiking.
The other unexpected bonus with this lens is the exception close focus distance of about 1m (3ft). Because of this, I find myself using this lens for a lot more “normal” photography, including portraiture, candids, and even “telemacro” of flowers, insects, and the like.
Overall, this lens should be in the kit of any Canon shooter needing a telephoto lens in this range. The combination of performance, ruggedness, and versatility make it a lens you will find yourself using constantly.
