L-series quality
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.

Lightweight and versatile
The EF 24-105mm f/4L IS USM offers a 4.3x zoom ratio, from wide angle to medium telephoto. It is highly portable, weighing just 670g.

Fixed aperture
The f/4 maximum aperture of the EF 24-105mm f/4L IS USM is fixed throughout the lens' focal-length range, so shutter speeds will not change as the lens is zoomed.

Image Stabilizer
The EF 24-105mm f/4L IS USM features Canon's three-stop Image Stabilizer (IS), making it ideal for handheld work. IS permits the use of shutter speeds up to three stops slower than normal, with no perceptible increase in image blur from camera shake.

Super UD and aspherical lens elements
The lens incorporates a Super UD (ultra-low dispersion) glass element to eliminate secondary chromatic aberrations. Aspherical lens elements correct for spherical aberrations. The result is crisp, high-contrast, undistorted optical performance throughout the zoom range, without colour fringing at high-contrast edges.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.

Smooth background blur
A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background.

Accessories
A petal shaped hood and soft case are included.
