EF 24-105mm f4L IS USM
When manoeuvrability is important and lens quality crucial, the L-series EF 24-105mm f/4L IS USM stands alone as the professional's lightweight standard zoom.
L-series quality.
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.
Lightweight.
Weighing just 670g, the EF 24-105mm f/4L IS USM offers 4.3x zoom in a lightweight body.
Fixed aperture.
With no change in aperture over the full focal length range, photographers can set exposure at the widest aperture and zoom through to 105mm without slowing shutter speed.
Image Stabilizer.
The EF 24-105mm f/4L IS USM features Canon's 3-stop Image Stabilizer (IS). Ideal for handheld work, IS allows use of shutter speeds up to 3-stops slower with no perceptible increase in image blur.
Super UD and aspherical lens elements.
The lens incorporates a Super UD (ultra-low dispersion) glass element to eliminate secondary chromatic aberrations and aspherical lens elements to correct spherical aberrations. The result is crisp, high contrast, undistorted images throughout the entire zoom range without colour fringing at subject outlines.
Auto focus.
A ring USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive responsive, near-silent high speed auto focus. Good holding torque stops the focusing lens group with precision without overshoot. Full time manual focus override is available without having to switch out of AF. Minimum focus distance is 0.45m throughout the zoom range.
Super Spectra coatings.
Optimised 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 colour balance and increase contrast for vivid hi-fidelity images.
Pleasing background blur.
An almost perfectly circular barrel aperture helps to create an even and attractive background blur.
Accessories.
A petal shaped hood and soft case are included.
