The EF 24-105mm f/4.0L IS USM is a professional EF mount wide-to-telephoto zoom lens. It was introduced by Canon in 2005 to complement the well-regarded 17-40mm f/4L USM and 70-200mm f/4L USM.

The EF 24-105mm f/4.0L IS USM is a professional EF mount wide-to-telephoto zoom lens. It was introduced by Canon in 2005 to complement the well-regarded 17-40mm f/4L USM and 70-200mm f/4L USM.
The lens is often compared to the other L series zoom of comparable range, the 24-70mm f/2.8L USM, losing 1 full stop but gaining IS in return. It also has rubber gaskets for moisture and dust protection, although this feature is only fully realized if the photographer uses a weather-resistant camera body. Some early production models of the lens had a flare problem (reportedly the first 10,000 batch) and Canon offered to repair them for free.
On a 1.6x APS camera body, this lens' field of view is equivalent to that of a 38mm - 168mm lens on a 35mm film camera; this is a very useful range, covering most normal to medium-telephoto needs.
