NJA Canon EF 100-400mm f/4.5-5.6L IS II USM Lens

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.

It's a great lens. I tried it and found it is very sharp lens that can help me reach any target.

I have two EF 100-400mm lenses; repaired#1 and during which bought #2... LOVE the lens Whether wildlife, florals, long or short... Too - - works very well with the 1.4 extender lens. Highly recommend!

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

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.

It is beautiful and most I enjoyed lens ever. Almost it is my go to lens.

Sharp, easy to use lens. Compact and not too heavy. Sharp at all focal lengths too. I enjoyed this lens a LOT.

Excellent clarity and separation of subject and background (bokeh). Photo is handheld on 5dIV body

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

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. It's my "walk around" lens, because of all this. Other photos seem to emphasize the telephoto capability. I'm here to say that it's also a great close-up choice. Not selling the DO or the macro, but I put them on the camera for their purpose, not grab shots.

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.

Excellent wildlife lens. Fast focus! Tack sharp images and great color.

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!

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.

I use this lens primarily for bird and wildlife photography, and it works great.

Bought this a few months ago and enjoy this product

bought this lens 1 year ago , just love it cant put it down .

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. You will NOT be disappointed!!

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.

OMG! This lens is epic for sports photography especially when paired with the EF 1.4 X III extender. Super clear images of surfing action. so glad I went for it. If you are shooting sports this is the go to glass to have!
