I bought this lens about 2 months ago at £435 which was the cheapest I could find at the time.. absolutely gutted that it's dropped in price so much but thought I'd share the deal with you guys anyway. It's the same price at Jessops if that is more convenient for people (as you can collect instore same-day). This is a great all round lens too - and for this price its a steal!

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.
Compact, lightweight and a wide magnification range - this standard zoom lens features a wide focal length range from normal to telephoto equivalent to 29-320mm in the 35mm format. It features an optical image stabilizer for up to 4-stops of effective correction even at full zoom.
Since Canon's optical image stabilization system is in the lens, not in the camera, you can see the stabilized, steadier images through the viewfinder. And the circular aperture can give beautiful background blur effects.
This wide zoom ratio EF-S lens delivers excellent high-speed performance at an affordable price.
