1. 400mm with image stablelizer. 2. Use 2x and 1.4x made it a powerful super tele(Forget using Velvia or Provia 100 in this case, Use Provia 400 instead) 3. Compare to 600mm 5.6 , it is not heavy.

1. Push and Pull zoom, make it easy to get dust inside the lens.

1. This camera have wide range of zoom power and sharpness of picture. 2. Image stabalizer realily work. Although tripod is recommend for long zooming 3. You can use it with 1.4x and 2x to give you a 1120mm zoom, although it is not recommend by the manufacturer. And you should use at least 400 film to get resonable shutter speed. But the photo is acceptable. 4. It is heavy but when compare to 400mm or 600mm prime , it is very light. 5. I buy this one for taking phot of bird on mountain. And its performance is rather good.

sharp crisp pictures, wonderful blur when zoomed in at wide open aperatures, look like a million bucks

Front heavy when mounted....but can be off set by using a motor drive, Slow focus in low light situations, and kind of heavy for quick lens changes

The 100-400 IS lens is one of the best zooms i've used. I purchased it for shooting soccer games and outdoor events, it its wonderful. I have traveled with it and its great to zoom in on small objects.....wonderfully sharp. The one thing that really stands out is the weight on the camera body....it very front heavy. I use it on the EOS 3 and the best way to off set it for comfortable use is to use the motor drive mounted. Makes for a big almost intimidating looking setup, but it works as great as it looks. I sue the 28-135IS a lot and it is a pain to swap this lens off and on if your on a trip. Not the lightest thing in your bag, but well worth its weight for outdoor use. In low light it really slows down as far as auto focus goes, and a tripod is a must. Keep this for daylight situations and you won't regret it one bit.

28-135 IS zoom....but this is the first long zoom i've owned from canon

- very good optics: not in the class of the big primes, but cream of the crop when it comes to big telephoto zoom. - the IS is fantastic. I've taken handheld (braced) shots at 1/10 that came out quite sharp. I wouldnt blow them up to 11x14, but they make reasonably sharp 5x7s. I can get enlargement (11x17) calibre sharpness at 1/90 at max focal l. - robustness: I got charged while photographing an ele in Zimbabwe. In the ensuing chaos, my tripod/EOS 30/100-400 toppled over, landing on the lens hood at an angle. The zoom got a little stiff for a few days but after some zooming in and out - no problems.

- Enough has been said about the push-pull zoom, and I agree that it isnt as convenient as a twist-zoom. However, this isnt a deal-killer flaw. I found it quite easy to adjust and soon was using it without any problems. Also, I've found that if you take some basic care, it is easy to avoid the problem of getting too much dust inside the lens. After 3 months of backpacking in Africa, there is minimal dust inside.

Perfect lens for traveling wildlife photography. It isnt the same calibre as tele primes, but is a big step up from other zooms in this price range.

I was on a trip with someone who had a Sigma 170-500. That is probably a better bargain in terms of price (picture quality that approaches the 100-400), but loses out on the lack of FTM and more impor

Image Stabilization really works! Not a small lens, but still light enough to carry around. Great reach for the weight. Strangers on whalewatching boats and similar situations sometimes get out of my way without me even asking, so I can get the shot!

Not a very fast lens. It does not excel in poor lighting. It will tempt you not to use a tripod, but you should still use a tripod with it when possible. The strangers who get out of your line of sight will then ask you if you work for National Geographic. Push-pull zoom design is clunky, but is liveable. Compact for its focal length, for easy packing in an airline carryon. As with most Canon "White lenses", the paint rubs off easily, making the lens look like it has been through a war!

This is my favorite lens. It does have its limitations, but this is an outstanding product. I find it very useful for animal and nature photography. It makes an excellent lens for those who can't/won't afford a super-telephoto lens, but who want a reasonably long lens. It's also valuable if you are allergic to tripods (though I recommend using it on a tripod, despite the IS). Canon states that you should turn off the IS during tripod use, but I leave it turned on with no noticeable negative effects.

IS makes a big difference. Good overall range Hood included

A little sluggish to focus IS eats batteries Tripod ring not like old 80-200 ring. Price High but you get what you pay for.

Purchased this lense for Outdoor photography mostly animals and birds. I also occasionally do some sports photography. This lense is great for all of those things. Used it to photograph 2 baseball games with excellent results. I did discover that with IS on the cameras batteries go a lot faster. I haven't found the push-pull zoom to be a problem particular since the feel can be adjusted.

As previous review, but may need regular servicing under certain conditions.

Very prone to dust, especially in countries like Africa. The interior of the lens may neeed cleaning after every trip. This can be very costly over time. My conclusion to this is think twice about purchasing this lens if you intend going to Africa, India or such places on Safari. A fixed lens may be a better idea.

I placed a review of this lens 12 months ago and since coming back from safari in Africa I have had some problems with this lens. The IS works eratically in vertival mode, and the lens sucks in dust like a vucum cleaner.

IS System Good range for bird photogrpahy Another well designed Canon product

Expense Heavy

What a remarkable lens for the outdoors and sports! I have little need for a tripod with the IS system involved, yet it is heavier than most other lenses I've used. Good for action shots, as well as a mid-range for photographing wild birds. It is less expensive than purchasing three high-quality prime lenses within the same range.

Build, ruggedness. We dropped this lens with the D30 attached. The lens was fine, the D30 had to be sent for repairs. The lens is sharp, and the IS sets this lens apart from other zooms in this range. The lens has a locking ring to adjust the slide of the pushpull of the barrel. Excellent value for the price.

Bulk? Power drain with heavy use of IS (very minor point)

I bought this lens after my EOS cameras and gear were stolen primarily as a replacement for my 70-200 f2.8L and 1.4x and 2x extenders. The build is very similar to my 70-200, noticeably slower focusing on the D30 compared to the 70-200, but still acceptable. Image quality is excellent, but not stunning as it was on the 70-200. I found it extremely useful when shooting outdoor weddings and sports where its range allowed me to get shots that previously I had to run for. Like all my previous L lenses, it is very sharp through out its zoom and aperture range, though somewhat softer than the 28-70 and 70-200 L lenses I used to have. The IS feature really does work, although it drains juice from the D30 noticeably, although this is not a real setback with the battery grip available for the D30.

Customer Service

Excellent! not for this lens, but for the D30- fixed and returned in one week.

Image Stabilization is this lense's major selling point. Optically, it is fine, sharp and well corrected, but the IS sets it apart from the pack. The recent Nikon VR 80-400 is its only competition.

Heavy, expensive and doesn't handle very well. The push-pull zoom is a pain and makes the lens front heavy at longer focal lengths. I recently purchased the 300 f/4 IS and it is a better handling lens, by far.

I owned this lens for only a couple of weeks before I traded it for a 35-350L. This lens is fine optically, and the IS makes shooting in low light, or at low shutter speeds, fairly easy. The zoom range didn't meet my needs, though, so I traded it for the other one. My shooting style needs the better reach at the wide end of the spectrum, but if I were a birder, or long range sports photographer, I would have kept the 100-400 IS. It is very similar, in size, weight, cost and handling characteristics, to the 35-350L. This is a good lens for those who need the 100-400 focal length and who's shooting style would benefit from the IS.

IS is amazing! It''s built good and it has all around sharp shots and great quality shots.

Push-Pull, a little too heavy, and the price at most stores is a little too much for my taste.

An amazing EF lense, I''ve been using it for about 2 months now and have been very pleased with it so far. It produces wonderful, sharp and good quality shots! This is one of the only lenses I use anymore (along with 2 others), it''s good for all my needs. Nature, sports, people and just anything I see. Moving images aren''t blurred, it has a great quality build and it''s just all around a great lense.
