Canon EF24-105mm f/4 L IS USM Lens

The Canon EF 24-105mm f/4L IS USM lens is an easy-to-use standard zoom lens that can cover a large zoom area ranging from 24mm wide-angle to 105mm portrait-length telephoto.

The EF 24-105mm f/4L IS USM incorporates Canon's highest standards of precision optics. The L-series is Canon's flagship professional lens range, combining outstanding image performance and ultimate operability with dust and moisture resistant construction.

Canon's ring-type USM gives silent but quick AF, along with full-time manual focus. Moreover, with dust- and moisture-resistant construction, this is a durable yet sophisticated lens that meets the demands of advanced amateur photographers and professional photographers alike. 

Image Stabilizer

Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane.

The 3-stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions.

Superb Auto-focus

The ring-type USM motor found in the EF 24-105mm f/4L IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. Photographers can choose manual focus instantly and at any time simply by moving the manual focus ring without first having to switch out of auto focus mode.

Constant f/4 Aperture from 24 to 105mm

The EF 24-105mm f/4L IS USM offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 105mm without having to vary the shutter speed. It is the perfect lens for professional photographers looking for a lightweight and extended zoom alternative to its EF 24-70mm f/2.8L USM counterpart. The lens employs an almost perfectly circular barrel aperture, helping create attractive, defocused backgrounds.

Image Quality

To limit lens size and improve image clarity over the total image area, an Ultra-Low Dispersion glass (UD) element is used to eliminate the secondary chromatic aberrations that otherwise reduce sharpness and introduce colour fringing. Aspherical lens elements correct spherical aberration for crisp, high contrast corner-to-corner quality. By optimising Super Spectra lens coatings and lens element shaping, Canon's engineers have been effective in suppressing flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.

Super Spectra Coatings

Optimized Super Spectra lens coatings and lens element shaping suppress flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help achieve true color balance and increase contrast for vivid hi-fidelity images.
