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 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 lens had a flare problem (reportedly the first 10,000 batch) and Canon offered to repair them for free.[2]

This lens is available in kits packaged with the Canon EOS 5D Mk II, 5D Mk III and Canon 6D.

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.

Specs[edit]

  • The lens includes sealing against dust and water, although it is not waterproof.
  • It includes an 8-bladed curved diaphragm which remains nearly circular from f/4 to f/8.
  • Uses common 77mm filters.
  • Characteristic of zoom lenses, it exhibits some barrel distortion at its shortest focal length.
