Product Description

Manufacturer's Description

Zoom lenses are very convenient. The equivalent of two or more fixed focal length lenses in one unit. The maximum aperture of some zoom lenses changes as you alter the focal length, but through-the-lens (TTL) metering takes this into account to give correct exposure.

Canon offers this first EF telephoto zoom lens with a high-magnification zoom range of 100 to 400mm. This is the first L type zoom lens with IS (Image Stabilizer) system. The dual-mode IS mechanism corrects camera shake blurring equivalent to two shutter speed steps. The IS Mode-1 works for normal shooting and IS Mode-2 is suitable for panning shots of a moving subject, stabilizing images in viewfinder.

The optical system uses one artificial crystal fluorite and one Super UD (Ultra-low Dispersion) glass lens elements (3rd and 7th), which thoroughly correct chromatic aberration. The minimum focusing distance of 1.8m is achieved throughout zooming range. The floating system in rear focusing system is employed for the first time for EF zoom lens to achieve a high definition for the entire focusing range.

A ring USM (Ultrasonic Motor) drives high-speed and silent AF and full-time manual focusing. Linear zooming design with zooming friction adjustment ring gives a good operability of this lens.

    Its a great lens, the IQ is excellent for a zoom with this sort of range and the build quality is just what you'd expect for this sort of money and 'L' series. Ok, the IQ is not as good as the Canon 400mm primes, but you can take this out for a walk, and it zooms :-)

    The trombone zoom is easy to use even if you're used to the 'normal' twist zoom. It's supposed to be something of a dust pump and to deposit dust on the sensor, but so far I've had no problems. Focussing is generally quick and there's little or no 'hunting' for a correct focus, particularly if you have the minimum focus distance buttons set to help the lens.

    The IS is effective, but as it's first generation, there's only two stops available and you need to switch it off if you're using a tripod. You can switch it for panning shots. After a couple of afternoons out with the lens I think I can say it also eats the battery on my 400D so I make sure I've got a spare if I think I'm going to be using it a lot.

    The f4.5 min aperture means you're probably going to be using it with ISO 400 on anything but the brightest day if you want to keep the shutter speed up for hand held shots or moving targets.

    It's heavy. Not too heavy to prevent me from taking it out for two or three hours walk or using it hand held without too much problem, but it might be a good idea to try holding something of similar weight if you've got doubts.

    It's quite long. Stood on its nose I can just fit it into the Lowepro Nova4 bag I use. If your bag isn't as high, you might have problems.

    There's a 'friction' ring for adjusting the stiffness of the zooming action and you can move it from no resistance at all to completely locked.

    I have had mine for about 8 months and have taken about 300 shots with it.

    It has in every way surpassed my expectations for image quality on my Canon EOS 5D. Sharpness and contrast is really stunning, this is the best long focus zoom I have ever owned. For example I shot some seascapes across the bay from Westward Ho in Devon. The Saunton Sands hotel is over 5 miles away. It is possible to count the window panes on that building and to determine the gender of persons in the car park of the hotel. Close up it has given superb nature shots of butterflies and flower blossoms near to its closest focus of 1.8 metres. It is also an excellent portrait lens giving sharp images and pleasantly out of focus backgrounds.

    The Image Stabilisation feature allows use at full focal length at slow shutter speeds. I used 60th second with success which would be a tripod only speed with an ordinary lens.

    So what are the drawbacks. Well it cost over £1000 and it is a heavy item to carry around. Nonetheless I took it with me in a rucksack on a recent tour of Ireland and used it for about 15% of my shots.

    If I lost it I would definitely buy another

    I really like this lens.

    When you look at Canon's range of super tele lenses (zooms and fixed focals) the options are fairly limited unless you have seriously deep pockets and can afford one of their top of the range fixed focal length tele lenses for the ultimate in image quality. For the rest of us mere mortals there are lenses like the 100-400 IS L (it's still hardly cheap though!!).

    The lens offers a 2 stop image stabilizer which whilst not as effective as some other lenses which offer up to 4-stops of stabilisation is definitely welcome as trying to get clear shots with a 400mm zoom is a challenge no matter what and I'll take any aid I can! The IS has 2 modes, one for panning and one for all-round stabilisation.

    The lens is VERY well built. It's heavy and feels very substantial, you will know about it after a day lugging it around in your kit bag. It's white too and when fully extended with the hood on you will not go unnoticed. To counter the weight of the lens it comes with a collar so that when you put your lens/camera combo on a tripod it's the lens taking the weight and not the camera body and lens mount. The lens does not zoom with a 'normal' ring type control, what you do is push/pull the lens to the required focal length. It's quick but probably less accurate than a ring type control. I can't mark the lens down for this because I reckon this design choice has been made to keep costs down and to make a zoom of this range affordable to people like me! There is a collar on the lens that can be adjusted so the push/pull action becomes harder or easier - useful to avoid the lens creeping if you're pointing it straight up or down for example.

    Context: I use this lens exclusively with an EOS7D. It was my last lens purchase, the rest of the family being 16-35mm f2.8L, 24-70 f2.8L, 70-200mm f2.8L.

    Build quality, design and most of the ergonomics (operations) with this lens are superb, and just what you would expect from Canon L-Series Glass. One weak spot is the switch to flip Auto-Focus on/off, which can be fiddly to engage without removing camera from eye and looking at the lens barrel. You'll get it with practice, but slightly larger switches with a way to differentiate them at a tactile level would make a big difference...

    In terms of size, weight and basic operation, it is similar in many respects to the 70-200mm f2.8, except for the trombone zoom. In practice this is not an issue, and the latter feature quickly becomes a pleasure to use. There are no surprises here [save maybe pleasant ones] for anyone familiar with other Canon lenses.

    Everything gets interesting when we get to image quality, where IMHO my views differ from other posters. My experiences [after several thousand exposures with both this and the 70-200] are that they are very different lenses for very different purposes. This lens is great for creative portraiture; for shooting flora and fauna in ways that lets you bring in the subject. It can be good for close-up architecture and structural photography, where you want to focus on shapes, textures or details and move away from big canvas or traditional landscape shots.

    However, it's weakness appears to be anything moving... There are several reasons for this:

    1. The auto-focus is seriously slow in comparison with any USM lens. Unless you're shooting snails, don't be surprised if your subject can out-pace the auto-focus...
