The short editorial description of Canon EF 100-400 4 5-5 6L USM IS


Canon EF 100-400 4 5-5 6L USM IS:
The official marketing text of Canon EF 100-400 4 5-5 6L USM IS as supplied by the manufacturer
-The Image Stabilizer gives the equivalent effect of a shutter speed two stops faster .
-Minimum focusing distance of 1.8 metres at all focal lengths .
-Manual focusing possible in the AF mode (full-time mechanical manual focusing) .
-The wide zoom ring is covered with rubber for linear movement .

The EF 100-400mm f/4.5-5.6L IS USM is Canon's fourth Image Stabilizer lens. It is a high-performance L-series telephoto zoom lens offering sophisticated features and high image quality which is to succeed the existing EF 100-300mm f/5.6L lens. Besides having an Image Stabilizer, this new lens also features enhancements such as ring USM for silent AF, rear focusing, a longer focal length range, and fluorite and Super UD elements which correct secondary chromatic aberrations for high image quality. It is the first EF zoom lens to have both rear focusing and a floating system to obtain high image quality at all focal lengths. Compatible with Extender EF 1.4x and EF 2x. With the EOS 3, autofocusing (at the centre focusing point only) is possible while the EF 1.4x is attached to the lens.

Lens system
Focal length range (f-f)
Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).

Canon EF 100-400mm f4.5-5.6L IS USM features two IS (Image Stabilization) modes, allowing steady far-off shots as well as clear close-up portraits with a blurred background. The use of Fluorite and Super UD-glass elements largely eliminates effects fro...
Bottom line If you're in the market for a telephoto zoom with a pro-quality Canon L-Series lens for your EOS digital SLR, the Canon EF 100-400mm f4.5-5.6L IS USM makes an excellent choice. It's built to pro standards and delivers the performance to match. It's a b...
The Canon 100-400mm ƒ/4.5-5.6 IS USM telephoto zoom lens was released in September 1998. The lens uses an older ''push-pull'' zoom design that extends the lens from its length of 189mm (7.4'') to almost 260mm (10.2'') when set to its most telephoto settin...
Bottom line It's not surprising to hear people swear by this lens: in 1998, there wouldn't have been much else in the price range that would have been as sharp. The push-pull design doesn't appeal to everyone for a variety of reasons, but it's hard to deny the lens'...
The Canon EF 100-400mm f/4.5-5.6 USM L IS is a fairly old design dating back to the late 90s. I still remember those days when I used it on an EOS 1n ... with film if you remember those good 'ol days. Well, time goes by but it's still here - despite a...
Bottom line The Canon EF 100-400mm f/4.5-5.6 USM L IS is almost a boring lens but in a positive sense. It shows no extreme weaknesses nor strengths. You will find sharper lenses - primes that is - but it is very sharp for a zoom lens, especially considering its 4...

The Canon EF 100-400/4.5-5.6L IS USM is Canons premium telephoto zoom lens. It competes with the EF 300/4L IS and the EF400/5.6L prime lenses as a telephoto and with the EF 70-300/4-5.6IS as a wide range telephoto zoom. In this series of tests I sh...
There are many "alternatives" to the 100-400, and for sure it is not the right lens for everyone. If you dont need a lot of reach, and you want the best quality, the 70-200 f/2.8 IS is the best choice. Otherwise, if you dont mind size and...
Good Very versatile zoom range, ideal for wildlife, It is light and small enough be be carried everywhere, and it is easy to handhold, Excellent autofocus, Good image quality between 100 and 300mm, Minimum focussing distance of just 1.8 and macro rati...

The Canon 100-400mm IS L is a very high performance ultra-telephoto zoom. It's also a huge bargain because it's been in Canon's catalog for a while, so it's an incredible deal today for an ultrasharp super long zoom.The 100-400 is a fully professional L l...
