It's a good lens, have a look here
The high performance standard zoom lens
The high-quality EF-S 15-85mm f/3.5-5.6 IS USM is equivalent to a 24-136mm focal length lens (5.6x standard zoom). Designed for EOS EF-S mount bodies the lens covers wide angle and portrait focal ranges. It also offers a 4-stop Image Stabilizer as well as a close focusing distance of just 0.35m throughout the zoom range.
Versatile super zoom lens
The EF-S 18-135mm f/3.5-5.6 IS is a powerful all-in-one lens for EOS EF-S mount bodies. It features a 4-stop Image Stabilizer and a 7.5x super zoom range (approx. 29-216mm equivalent focal length). The lens covers a wide range of focal lengths with a 0.45m minimum focusing distance. A general-purpose zoom, it is ideal for photographers looking to make the step up from a standard kit lens.
Easy-to-use impressive image quality
Both lenses offer great low-light performance due to the inclusion of a 4-stop Image Stabilizer that automatically detects panning and tripods, responding accordingly to help photographers take steady shots in any situation. The addition of ultra low dispersion (UD) lenses and aspherical lens elements - as well as lens coatings optimised to combat ghosting and flare - ensure high quality throughout. Both products also include a circular aperture for beautiful background blur (bokeh).
