Product description from Canon
At launch 1998 Canon wrote this regarding Canon EF 100-400mm F4.5-5.6 L IS USM :
"L-series super telephoto zoom lens equipped with an Image Stabilizer. The fluorite and Super UD-glass elements largely eliminate secondary spectrum. The floating system also ensures high picture quality at all focal lengths. The Image Stabilizer has two modes and it is compatible with Extenders 1.4x II and 2x II."
Compatibility, autofocus and focal length
This lens is constructed to fit all models of Canon cameras, regardless of camera model or type of sensor.
The ability to use autofocus is available for all cameras.
The lens has a focal length of 100-400 mm. Depending on which camera the lens is used, the experienced and perceived focal length will be different. Please visit the list of compatible cameras below, it will provide the equivalent focal length you get on each camera.
A positive thing is that this lens has a versitale zoom range, where the difference between 'maximum zoomed out' to 'maximum zoomed in' increases the lens versatility since you as a photographer easily can compose your picture without moving yourself physically.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/4,5-5,6.
This lens is not considered to have a good aperture value and brightness. It is something to consider before you purchase the lens. To compensate for this you might, while photographing in less favorable light conditions, be forced to either use higher ISO settings (which generates more noise in the image), slower shutter speeds (which may give some motion blur) or flash lightning. Read more at the link below what lens brightness means to you as a photographer.
One thing to consider is that the lens has a variable brightness, which means that depending on how much you are zooming the lens will have a different maximum aperture value. At 100 mm the lens brightness is f/4,5 and at 400 mm the brightness is f/5,6. Through the link below you can read more about what this could mean for you as a photographer.
Inside the lens there is an image stabilizer, which helps to fend off possible movements and tremors. This is very positive and can be of great help in situations and conditions where the light is inadequate and not enough for decent shutter speeds.

Filter and Lens Hood
The lens has a traditional filter thread on the front and its measuring 77 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.
If you buy this lens it will come with a lens hood, whose model name is "ET-83C".
Tripod Mount
This lens is equipped with a tripod mount, which makes use of a tripod easier and more stable.
