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.

To meet user demands for a fast EF-S zoom lens, Canon has specially designed a lens with a large aperture of f/2.8 for select Canon Digital SLR cameras. The large circular aperture produces a shallow depth-of-field, creating background blur that draws attention to the photographic subject.

The lens construction includes UD and aspherical elements, which deliver impressive image quality throughout the entire zoom range. Image Stabilizer lens groups shift to compensate for camera movement so that the image appears steady on the image plane, ensuring clear, crisp images, even in dim light.

With a Ring-type USM, inner focusing and innovative AF algorithms, this lens achieves autofocus quickly and quietly, and with full-time mechanical manual focusing, manually adjusting the focus is possible even in AF mode.

Customer Reviews

This is an amazing piece of glass!
This lens has the same focal range as the 'kit' canon 18-55mm, so anyone with
that lens will know what kind of range it covers. But this lens is altogether
in a different league in terms of optical quality and price! But if you have the money, get yourself a copy, because used properly, it will amaze you. The build quality is what you can expect from a high end consumer canon. There is no hood or pouch, which is a shame, because canon could have included these. I would recommend this lens if you're serious about getting the best from your APS-C DSLR, and you are not intending to move up to full frame in the next few years.

The star of the EF-S range
I bought this when I had my 400D and it was the reason that I didn't go full frame when I upgraded. So it sits on a 40D now and I love it. The IS system is useful when hand held at it's maximum, and the optics don't let it down at all. If you have a 400 or 40 series using EF-S lenses then your kit is not complete without one.

dont let the price put you off
A truly exceptional item.
I've had this about a year now and it's hardly ever off the camera. Almost all of my other lenses now languish unloved at the bottom of my bag.
Canon make an "L" series of "pro" lenses and the only reason this doesn't get assigned an "L" designation is a plastic lens barrel and the fact that (apparently) Pro-s don't go for this focal range. Other than that it's pro-spec (with a price to match). Oh, and of course the fact that it's an "S" (short back), which means it's designed to be more compact and as such will only fit onto those camera bodies with a reduced size sensor (400d / 40d/ 50d etc and not the "full frame" models that pro's lug around).
Don't overlook the value of that fixed f2.8 across the range with the image stabilisation. With this you can pretty much dump your flash guns as well! It also focuses fast and silently (I forgot just how until I cleaned-off one of my older lenses recently).
If Canon made a 50-200 of the same quality and price range as this you could put all your other lenses on ebay as you wouldn't need anything else. I WAS going to knock half a star off for the weight (yeah it's a brick) but then again......so is my 40d so they do tend to balance.
Highly recommended. You will have to add another 25 quid though for a decent lens hood as for some reason Canon scrimp there and don't give you one.
