EF 24-105mm f/4L IS USM Lens
This easy-to-use standard zoom lens can cover a large zoom area ranging from 24mm wide-angle to 105mm portrait-length telephoto, and its Image Stabilizer Technology steadies camera shake up to three stops. Constructed with one Super-UD glass element and thee aspherical lenses, this lens minimizes chromatic aberration and distortion. The result is excellent picture quality, even at wide apertures. Canon's ring-type USM gives silent but quick AF, along with full-time manual focus. Moreover, with dust and moisture-resistant construction, this is a durable yet sophisticated lens that meets the demands of advanced amateur photographers and professional photographers alike.
Enjoy.
I own that lens and it is a great price for it. A versatile all-round lens … bought it for around $850 1.5 years ago.
When you don't have a full format body it's a nice lens and you can upgrade one day to a full format camera and still use it (EF mount).
Match it with the a nifty 50 and you have a nice starter lens set.
Saying that it is not my favourite lens … 4.0 is just not wide enough for me and I don't use it a lot anymore.
My dream lens in that range would be the 24-70II … but this is a bit more expensive.
