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

What can I say? "L" lens, awesome focus, crisp detail, great reach

It's not light. And the most unfortunate thing to date has been the pricing. Consistently higher than any other online retailer. At one point several hundred dollars OVER msrp. After being corrected, newegg declined to offer the canon rebate, making it...

Great birding lens. Crisp well focused images. Originally thought the f/4.5-5.6 might be a problem with light, however when I shot birds it is always outside and it has not been a problem. I don't use a monopod and the IS does great. Use the IS 2 mode...

With a 2X extender the auto focus does not work and this makes it 800mm. Trying to manually focus at 800mm makes the focus ring very coarse. As a result I take a few shots and refocus and take more in case the focus was not optimum. I was going to take...

Build quality is excellent ; So far images are tack sharp ; This lens is exactly what I have read about. I look forward to taking many great pictures with it

No unexpected cons. For a lens of this quality it is going to be expensive and heavy. I am replacing an inexpensive 400mm lens and this one is much heavier, but for quality glass and excellent build quality, this is expected

This is an awesome lens I cannot believe the quality. I was a little hesitant to by a 100-400mm lens but I am speechless as to its ability to work in any application. I have used it at Weddings out to taking pictures of waterfalls with Time laps. I...

It's heavy and Expensive but worth every penny

Excellent IQ (image quality), focus speed, build-quality. Includes case and lens hood. Attention getting. "Conspicuous display of fiscal throw-weight

Bulky. Older lens with limited IS (image stabilizer). Attention getting

Best price for 100-400mm range. IS feature is nice to have when tripod is not available but doesn't guarantee you have sharp shoot due to slower aperture. The picture will be sharper if adding extra stop only if light sources permit

Heavy - 48oz, however still lighter than Canon EF 70-200 f2.8L IS. Lower lighting source will require you to mount it on tripod to have sharp picture taken ; Push Pull design may collect dusts and require some time to be familiar

This camera is my first good DSLR and replaced a Canon S5 IS. What a difference! Reading the specs does not prepare you for how fast this camera starts, focuses, and shoots. I've shot mostly bird photos in a wide variety of conditions including: in my...

The kit lens is nothing to write home about, but it will suffice till I can afford a proper short lens

I took this lens out to go "bird hunting." Before today I had only taken just a few shots on it, most of which were lowlight and nothing too flattering ; At 400mm I could make out all the details on the wings of a Sand Crane while flying through the...

The aperture on this leaves a little more to be desired of, it is a light hog with the max aperture being 4.5. It is decent enough for daylight (and some cloudy) shots, so like any other slower lens, this will require a tripod at night ; The tension...

Image quality (L), stabilization, Looks, Great for portraits in adequate lighting ; I can hand-hold at full zoom! Amazing

It's heavy, but what would you expect

Consistent Output ; Durable ; Easily Interchangeable ; Fast / accurate auto-focus ; Nice Bokeh ; Rugged ; Strong Construction
