The EF 24–105mm f/4L 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/4L 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/4L 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/4L IS USM lens is available in kits packaged with the EOS 5D Mk II, 5D Mk III and EOS 6D.

The EF 24-105mm f/3.5-5.6 IS STM is a newer 'low cost' alternative to the EF 24–105mm f/4L IS USM. It has the same zoom range, but a non constant aperture range which is typical of many non-professional lenses. Both lenses have image stabilization (IS). The EF 24–105mm f/4L IS USM uses a ring type Ultrasonic motor, whereas the new EF 24-105mm f/3.5-5.6 IS STM uses Canon's STM Stepper motor, which is quieter during video usage. The new EF 24-105mm f/3.5-5.6 IS STM weighs slightly less (525 g / 18.52 oz versus 670 g / 23.6 oz) and costs roughly half the price of the EF 24–105mm f/4L 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.

Specs EF 24–105L IS USM lens[edit]

Optical scheme of Canon EF 24–105L IS USM lens
  • 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.
  • Like many Canon L-series lenses, it uses common 77mm filters.
  • Characteristic of zoom lenses, it exhibits some barrel distortion at its shortest focal length.
  • It contains a single Super-UD glass element (dark blue in diagram) and 3 aspherical lens elements (green in diagram).
