EF 100-400mm f/4.5-5.6L IS II USM Lens - Professional L-Series Telephoto Zoom | Image Stabilizer & ASC coating | Sports, Action and Wildlife

I am no expert on the technical side of this lens. I have previously used it on hire and was extremely impressed with the results when I used it at an airshow. Couldn't afford to buy it new but got a great secondhand deal on Amazon. Prompt delivery, well packaged very happy with my results when I first used it.

Gave the lens a major test at the Fairford Riat Airshow 2022 and it didn't disappoint......great lens...upgraded from the Mk1 .....get it you won't be disappointed.....came really well packaged and on time

Bought this and it is brilliant! I am a wheelchair user and so was concerned about using this lens on a couple of levels. But it is pretty easy use/set up. It is quite heavy but manageable. Great piece of kit from Canon!

The rumor mills have been churning for years now on a replacement for the Canon EF 100-400 f4.5-5.6 L IS USM which was initially released over 10 years ago. Finally Canon have come through with an update to this lens. The lens comes very well packaged from Canon with foam protecting just about everything, including the lens hood. In the box you will find the lens, tripod mount, front and back covers, a new ET-83D lens hood with a sliding door (about an inch square) that is very useful for circular polarising filters and a very nice carrying case which is very similar to the case the 70-200L f2.8 comes with. On the lens you will find switches for auto-focus/manual focus, full focus range or 3M to infinity (the lens will ignore near objects and only try to focus on objects further than 3 meters (about 10 ft) out or beyond), Image stabilization on/off and three different modes of image stabilization. The lens comes in Canons famous white L metal finish and is fully weather sealed (you do not need a filter to complete the weather sealing like you do on some other L lenses that I have). The build quality of this lens is excellent as you would expect from any of Canons L series lenses. Rather than the old, dated push/pull mechanism of the previous lens, this lens uses the normal rotational zoom with the barrel extending out from the main body. Canon has used an internal floating focusing mechanism which results in non-rotation of the front element (something you want if you are using graduated filters for example). The zoom ring is strangely at the front of the lens whilst the rear ring is focusing (this is essentially a reversal of what you normally find). Both the zoom and the focusing rings have a smooth motion to them giving you excellent control over both with a friction ring directly behind the zoom ring allowing you control and locking of the zoom. Canon have updated their Image Stabilization to the latest and greatest which according to the specs allows you an equivalent 4 stop gain. The IS really is very good however in the few tests that I have managed to complete, this is more of a 3 stop gain, not 4. You now get 3 flavors of image stabilization as well as tripod detection so the IS doesn't have conniptions by the lack of movement anymore (a great feature if, like me, you sometimes forget to turn IS off when you mount the lens on a tripod). The front element has a new ASC (Air Sphere Coating) which is supposed to reduce backlit flaring and ghosting whilst the fluorine coatings on both the front element rear lens surfaces is meant to help reduce smears and fingerprints. The lens also features an upgraded USM ring-type drive which results in extremely fast and virtually silent auto focus operations. You can manually focus the lens in auto-focus mode and sometimes this helps when going from near focus at full focal length to far focus. There can be little focus hunting when you do this. So how good are the optics? The center of the lens is tack sharp, in fact the lens as a whole is extremely sharp but there is a little fall off towards the edges, and by a little I mean a very little. The peak lens performance occurs seems to be around 190-220mm with the weakest spot not surprisingly being at the full 400mm but even at 400mm this lens is very sharp. There is slight vignetting the further you zoom out, again nothing to be worried about and there is virtually no chromatic aberrations (color shadows/fringing at image borders). You will not find a creamy smooth bokeh like you find on a f2.8 prime on this lens, that is to be expected but it is better than the original 100-400L and is generally very good. If you are a pixel peeper you will find a slight halo around the out of focus discs but you have to zoom quite far in on your image for it to be noticeable. Pros : Image Sharpness Image Stabilization Flexibility of the lens USM focusing is very fast and silent Cons : Bokeh isn't as creamy smooth as other L prime lenses but still very good. The image quality of this lens is outstanding and the build quality superb. The focal range of 100-400mm (160-640mm on an APS-C camera) gives you more options than say the 70-200mm especially for wildlife and sporting events. Did I mention the tack sharp image quality? It really is so good that I'm seriously considering whether I need to carry both this lens and the 70-200mm f2.8L in my bag, which gets to heavy with both lenses, or whether I can just leave the 70-200mm at home unless I know I am going to need its lower settings. canon have done a wonderful job with this lens and it is a significant improvement over the mk I. A couple of other things worth mentioning. This lens does work with both the Canon 1.4x and 2.0x TCs and also the Kenko 1.4x Pro 300 TC with full autofocus. It also works with the MetaBones III adapter with full autofocus if you are thinking of using this lens on a Sony A7 or A7R. When used in conjunction with the MetaBones III adapter the autofocus does take a lot more time to lock in and you will notice some slight hunting but combined with the A7/R sensor it creates some sensational images.

Good product

Thanks to Apario retail and Amazon for giving me the 100-400 is ii lens at approx Rs168000/- Got a fresh sealed piece. The Canon camera square shops were not able to get this lens. I had to do microlens adjustment on my Eos 90d to get very sharp images. I can take sharp photos handheld with this lens the is ii is too good. I registered it on canon web site and got a 2 year warranty . It is also a good video lens . I use it without tripod , i consider to buy a gimbal head when its prices come down .

Es un lente de calidad premium , llegó perfectamente empacado y muy rápido; antes de comprarlo vi múltiples reseñas en YouTube y todas indicaban un excelente desempeño y alta calidad, y es correcto su auto enfoque es muy rápido, la calidad de su óptica excelente; aunque se debe considerar que es un lente pesado 1.6 kg

Just buy it, you won't regret! Far superior to other lenses, with constant results and a Canon L built quality. This lens is very sharp, very fast and is having a short distance focus.
