The EF 24–105mm f/4.0L IS USM is an 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 lens is often compared to the other L series zoom of comparable range, the 24–70mm f/2.8L USM, losing one full stop but gaining image stabilization (IS) in return, stabilizing camera shake up to three stops. It also has rubber gaskets for moisture and dust protection, although weather sealing is only effective if the photographer uses a weather-resistant camera body and a lens filter. Some early production models of the EF 24–105mm f/4.0L IS USM lens had a flare problem (reportedly the first 10,000 batch) and Canon offered to repair them for free.[1]

This EF 24–105mm f/4.0L IS USM lens is available in kits packaged with the Canon EOS 5D Mk II, 5D Mk III and Canon 6D.

The EF 24-105mm f/3.5-5.6 IS STM is a 'low cost' version of the EF 24–105mm f/4.0L IS USM. It has the same zoom range, but a non constant aperture range. Both lens have image stabilization (IS). The EF 24–105mm f/4.0L IS USM is using USM as engine whereas the new EF 24-105mm f/3.5-5.6 IS STM is using STM as engine, which is more silent during video usage. The new EF 24-105mm f/3.5-5.6 IS STM has slightly less wiegth (525 g / 18.52 oz versus 670g g / 23.6 oz) and hast the half price of the EF 24–105mm f/4.0L IS USM. [1][2][3][4]

On a 1.6x APS-C camera body, this lens' field of view is equivalent to that of a 38–168mm lens on a 35mm film camera; this is a very useful range, covering most normal to medium-telephoto needs.
