The Canon EF 15-85mm f/3.5-5.6 IS USM is a very attractive do-everything lens for Canon's 1.6x ("APS-C") cameras.

It covers the same range as a 24-135mm lens would cover on a full-frame camera, this is the range you need in 90% of travel photography. It has Image Stabilization (IS) providing up to a 4-stop compensation for image blur caused by camera shake at slow shutter speeds, you may grab the focus ring at any time for instant manual-focus override, and it focuses super-close, eliminating the need for a separate macro lens.

Product Highlights

  • EF-S Mount Lens
  • 24-136mm (35mm Equivalent)
  • UD and Aspherical Lens Elements

  • Ultrasonic Autofocus Motor (USM)
  • Manual Focus Override
  • Lightweight and Compact Design

The Canon EF-S 15-85/3.5-5.6IS USM is a replacement for the original EF-S 17-85/4-5.6IS USM and it offers a number of improvements:

  • A wider view at the short end of the focal length range, 15mm vs. 17mm. In 35mm field of view terms this is equivalent the to difference between a full frame 24mm lens and a full frame 27mm lens, a useful increase.
  • A revised optical design with 2 additional aspheric elements and one UD element. This improves image quality (especially at the edges of the image at wideangle settings)
  • The IS system has been upgraded and Canon rate the 15-85 IS as good for up to 4 stops of stabilization vs. the 3 stops of the original 17-85 IS
  • The diaphragm has one additional blade (7 vs. 6) which should improve the smoothness of out of focus areas of the image (better bokeh)

Since this is a variable max aperture zoom, you have to keep an eye on your shutter speed and ISO levels, especially if you constantly zoom in towards the telephoto end. By 50mm, this lens can only offer you f/5, which is on the slow side of things. Even the cheap EF 50mm f/1.8 II would be a better choice for indoor portraits.
