  • Took years to get here but worth the wait
Style: Lens Only
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. ... show more

  • My first great white lens
Style: Lens Only
This is my first L lens. Recently upgraded the camera body to a 7D mark ii to capture actions in my kids' soccer games. The kit lens (EF-S 18-135mm STM) that came with the camera shows its limitation in focal length, so I need a longer telephoto lens. Setting my heart on a L lens and determining that I will need a focal length bigger than 200mm, I zoomed in on the 28-300 L, the 70-300 L and the 100-400 L (mark i). Quickly eliminated the first and the third due to push-pull, and almost ready to buy the second for its price and reach albeit with some hesitation on the lack of tripod mount and incompatibility with Canon teleconverters, when I saw the all new 100-400 L (mark ii). The reviews on both Amazon and B&H are mostly very positive, and the new technologies in the lens seem to be resistible. So after a brief self consultation of cost and benefits, I've made the purchase on Amazon. The lens arrived a couple of days ago; delivery was prompt - thanks to Amazon Prime. I have yet to bring it outdoors nor to shoot my kids' games, so I cannot say anything of how it performs in the "real world" - will try to update this review when more data is available. However, I can already say something cosmetic about this lens. First of all, it is heavy. At over 3.5 lbs, this lens is a monster. Mounted on a 7D mark ii, the combination is way over 5 lbs. I am still improving my muscle memory (and it's getting better by the day), but I can say that hanging this thing on my neck is certainly not a pleasant experience. Having said that, hand-held shooting position is actually not too bad; I don't think I'll need any mono/tripod during the soccer shootings. I'll probably carry the camera with lens on over my shoulders when moving around during the games. Secondly, the image stabilizer makes a distinctive clicking sound when it's turned on and off in AF mode. This is a bit annoying compared to the almost silent operations of the STM lens, but I guess I'll have to get used to it. In live view, the sound from the IS motor is not audible, but the movement of the lens elements can be heard when zooming. Hope this won't ruin the video recording. Third, there is a small opening on the lens hood, which can be used to control the polarizing filter. Sometimes I found this little "window" to be too easily opened by accident; so need to pay attention to make sure it is shut. Overall build quality, feel, and image quality from a few test shots in low light conditions look very good. Can't wait to take it out to realize its full potential, and see what/how the great white lens delivers. Update 6/18/15: I've now owned the lens for a few weeks and taken it out for a few outdoor kids sporting events. Under good lighting condition (sunny sky), the lens (together with my 7D Mark ii, manual setting at 1/1000, largest aperture at respective focal length) delivers sharp image, vibrant color, and high quality (ISO lower than 400). However, in one of the settings with overcast sky, maintaining the same shutter speed and aperture rendered pictures with ISO consistently over 2000 and sometimes at 4000. The image quality is obviously less stunning than those at ISO below 400 shot in bright sunlight. Well, one could argue it is the sensor on the 7D Mark ii. But I think the maximum aperture of f4.5-5.6 of the lens also plays a role. So the conclusion is that the lens is perfect for sports in good lighting conditions or slower moving or stationary objects in not so ideal lighting; but may push the limit for actions in low lighting (e.g. indoor sports or stage). ... show more

  • Expensive? Yes. Worth it? You bet! Expensive? Yes. Worth it? You bet!
Style: Lens Only
Let me just preface this post by saying that a $1700+ purchase is not a drop in the bucket for me and I had to sell several pieces of equipment to make it work. This lens is replacing a 70-200mm f/4L (non-IS) and a 300mm f/4L (non-IS, yes, one from 1992). I wanted something with really good reach and great image stabilization. About 6 years ago, I rented the Mark I, push-pull version of this lens so I could cover Air Force One and Obama's arrival in San Francisco for a website contribute to. I was impressed with the reach, but the images were a bit soft compared to other really nice L glass I've owned and used. I debated long and hard between getting this lens and the 70-200mm f/2.8L IS Mark II + 1.4x III, and ended up with this lens. Primarily, I didn't want to have to deal with a teleconverter. Plus, I knew I'd be shooting at 400mm a lot, and there is a slight decrease in quality with the 1.4x III on the 70-200 compared to this new 100-400L. To save a few hundred dollars, I bought this used -- something I'd recommend to people as long as the website has a return policy for third party vendors, like Amazon does. Here's what I like: 1) Image quality is fantastic. From 100-400, throughout the entire range, contrast and color are rendered superbly. 2) Sharpness is top-notch, even at 400mm and wide open. I'm just blown away with how good the wide open performance is. 3) Image stabilization is fantastic, and truly necessary for 400mm hand-held shots. I do fully believe it's good down to 4 stops as advertised, as I am able to get sharp images 3 out of 4 times at 1/10sec and almost every time at 1/20sec for a stationary object at 400mm. Make yourself familiar with the different modes and how they work in order to be most effective with the stabilization. 4) Macro ability. You can focus down to about 1 meter (3 feet), which means you can get some great up-close shots. 5) Bokeh. Fantastic separation and bokeh quality. What I don't care for: 1) The tripod collar foot. It's hard to get on and off. I even chipped the paint trying to forcibly remove it once when it was stuck. I have since learned not to over-tighten the wheel. 2) The weight. Yeah, I knew what I was getting into when I bought this monster. Make sure you have a good strap. I use the Black Rapid RS-7, which helps my shoulders and neck a lot. 3) Lens creep. The locking mechanism for the zoom is good, but not perfect. It's also not convenient to use, so half the time I don't use it, and the lens creeps anyway. I suppose this is equally my fault and Canon's fault. Mine for not using it, and theirs for not making it easier to use. Overall, this is a hell of a lens. There are few things that are better for pure image quality and versatility. Expensive? Yes. Worth it? You bet! ... show more

  • Canon Quality, as expected, Great improvement over the old version of this lens
Style: Lens Only
Had the old version 1, of this lens, since it was released over ten years ago, which has and still serves its purpose. However, the new and improved/enhanced updates to the new version II, sold me right away. If it increases my chances of getting a better pictuce and capturing birds in flight more efficiently, I am all for it... Took it out to a local lake, was misty and cloudy and damp, not ideal for taking photo's, but, was able to catch several American Pelicans in flight, though the photos came out darkish, when I looked at them on my computer and enlarged them, I was struck by the focus and clarity of the images, could see the orange around the eye of the pelican, I would never have expected this, I could see the improvement in the lens and auto focus systems. Added a 1.4 extender III, and though there is some drag in aquiring the image, it will focus quickly,once your locked in on the image, much better than version 1, of this lens. I still enjoy the Tamron 150-600mm lens, excellent on sunny days, the images are exceptable/keepers, however, canon still has the eadge, on image quality. The instant 600mm reach of the Tamron, still earns a seat beside the Canon, I use both extensively. I will hand hold the canon 100-400, but always use something to support the Tamron, tripod or window of the car, etc. Took several pictures with the Canon 100-400 with the 1.4 III extender, of a snow goose resting about a 50 yards away, and despite the weather, the eyes and feathers were very sharp and in focus, this also atest to the improved stablization system, my old 100-400mm, many times, seems to show some blurriness, when hand held. Appreciate the 3 stablization modes, expecially the panning setting, will use this extensively. I use a canon 7d mark II. Have a full frame but use it mainly for landscapes, haven't had a chance to test it with this lens as of yet. As usual, canon arrived late, with this lens, was well worth the wait, with these advancements to the 100-400mm II. ... show more

  • I'm glad I waited for this Lens, just perfect.
Style: Lens Only
I purchased this last weekend from Amazon and it arrived promptly, nicely packed and no scratches, even on the box. I tested it out, and all I can say is wow !. The lens is pretty heavy but compact for a 400 mm f5.6 maximum reach, its about the size and weight of a 70-200 F2.8 zoom. The IS is absolutely silent and good for at least as many stops as any other Canon IS good for 4 stops. This lens does it at 400 mm whereas the other lenses are wide, normal to short telephotos (i.e. 200 mm or less), so I think this is a real achievement at a super-telephoto reach. The lens is extremely sharp, atleast as sharp as my 70-200 F4 IS at 200 mm (which is this lens best focal length for sharpness) at 400 mm! Its even sharper at 200 and 300 mm, although 100 mm is its weakest focal length. Even at 100 mm, its very good, wide open, so you can imagine what it does at 200 and 300 mm. Its built very solid (mostly metal, including the filter ring). I'm glad I got this instead for the 70-200 F2.8 IS II which is one of the best zooms there, since this lens keeps up with that lens in all respect except for the 2 stop speed. I really don't need the similar weight just for the faster speed, I would rather use f2.8 or faster primes if absolutely necessary or use the f4 zoom at half the weight. This is about as heavy a lens I want to hand-hold and the IS really makes this a solid choice. I would compare this to other 400 mm lenses not 300 and 200 mm lenses, and the extra weight is then justifiable for what it brings to the table. ... show more

  • A worthly upgrade to a great lens.
Style: Lens Only
I had the original 100-400 mm lens for about five years for my nature/wildlife photography and I logged over 300,000 photos with it. I probably had a great copy because it was capable of excellent sharpness once it achieved focus. The only thing that bothered me with it was that it often failed to achieve full focus, especially at close range on flying hummingbirds resulting in less than 40% keeper photos on rapidly moving birds. (Keeper being defined as being able to see fine feather details) It was capable of excellent focus and resolution on stationary or slow moving subjects such as ducks on the water. I have had the new EF 100-400mm f/4.5-5.6L IS II for about three weeks now and have shot around 500 pictures, mostly of flying hummingbirds. My observations are: 1.) It is capable of greater sharpness than my original 100-400mm lens, but not by much. 2.) It focuses more quickly and accurately than the original model under all conditions. My percentage of keeper photos at close range with fast moving birds is much higher. 3.) Color and contrast is improved over the prior version with a very noticeable improvement. I will update this post after I have taken 2000 or so pictures with it. In general I am glad that I upgraded to the new lens as the enhanced picture color quality and improved keeper percentages are worth the cost. Now if I can only get used to twisting the zoom ring instead of pushing and pulling it. ... show more

  • After Waiting Three Years...
Style: Lens Only
This first section reviews the first lens I received which turned out to be defective. Please check below the line where I speak about the replacement lens. I hate to be writing this. I have waited three years saving up for this updated lens. In the meantime I have been using a Canon 70-300L which has performed wonderfully. First, when it works, the lens takes absolutely gorgeous pictures. The colors even seem to be better than any of my other lenses. I pre-ordered the 100-400 II lens and received it one week ago. I have taken it out twice mounted on a Canon 7D generation 1. The first time, after taking several shots, I switched it to the 3m - Infinity range setting. After one successful shot, I started getting Error 01's, which is a lens to camera communication problem. When I switched the range setting back to Full, it worked again without producing the error. The advice given for this error was to clean the lens contacts which I did. The lens now worked in both the Full and 3m - Infinity range settings. Problem solved, I thought. Today, I took the lens out a second time, again mounted on the 7D. I took perhaps 50 successful shots. Then I pointed it almost straight up for a shot of a Bald Eagles' nest. Boom! Error 01. This time, cleaning the contacts has not solve the problem. I even tried a solution posted online: shooting without a lens, with the lens half mounted, then again fully mounted. No luck. The lens now fails in all range, focus and stabilizer settings. After one week and two outings, this brand new 100-400 II lens seems to be toast. The 7D works fine with the Canon 70-300L, the new Sigma 18-200 and the Canon EFS 15-85. The problem is not with the camera. An internet search reveals this was also an ongoing problem with the old 100-400L. I really wanted to love this lens. I still want to. If I can get this Error 01 problem solved, I'll be back to update this review and give it the rating it should have. UPDATE 12/27/14: Cleaning the contacts with solvent did not work the second time. I tried using the eraser end of a LensPen. I am happy to say this got it working again. It remains to be seen if this is a permanent fix or if it will keep failing. UPDATE 12/28/14: Got it working yesterday. Today, getting ready to take it out, I get Err 01's again. All of my other lenses work fine. This one is seriously flawed. It's a $2,200 paperweight. I am returning this lens to Amazon for replacement. UPDATE 12/29/14: Five stars to Amazon for how they are handling return and replacement of the lens. They provided a prepaid shipping label for the return, and sending a replacement with one-day shipping. --------------------------------------------------- UPDATE 1/6/15: I am back to revise my review after receiving the replacement lens. Again, I can't praise Amazon more highly in how they handled the return and replacement. It took just one week to receive the new lens which arrived yesterday. Today, I took it out, again mounted on the first gen 7D. I am delighted to report that I took over 200 shots at three different locations without receiving a single error code. The lens performed flawlessly in both range settings. I am absolutely amazed at the photos I am getting with this lens. I always thought the 70-300L was a great lens. This new 100-400L is an order of magnitude better based on the shots I am getting with it. I am not an experienced photographer, but using this lens, I might be able to fool a few people. I am taking my best pictures ever with this lens. With this lens, I am lugging around an additional 18 ounces compared to the 70-300L. The stock Canon instrument-of-torture neck strap won't do at all. I have been using an OP/TECH 1501372 Pro Loop Strap for Camera Equipment (Black) and I find it quite comfortable with this lens. For me, the 100-400L II really is a five-star lens. This is the review I wanted to give it. ... show more
