Quality of the L series
The EF 24-105mm f / 4 L IS USM incorporates Canon’s highest standards of precision optics. The L series is the range of main professional objectives Canon, combining outstanding image performance and maximum ease of use with rugged construction to dust and moisture.
Weighing just 670g, the EF 24-105mm f / 4 L IS USM offers 4.3x zoom in a lightweight body.
No change in the opening over the entire range of focal lengths, photographers can set exposure at the widest aperture and zoom to 105mm without slowing shutter.
The EF 24-105mm f / 4 L IS USM includes an image stabilizer (IS) Canon 3 levels. Image stabilizer, ideal for working without a tripod, allows the use of shutter speeds up to 3 levels under no perceptible increase in image blur occurs.
Aspherical lens elements and Super UD
The objective incorporates a Super UD glass element (ultra-low dispersion) to eliminate secondary chromatic deviations and aspherical lens elements to correct spherical deviations. As a result, sharp images with high contrast and distortion are obtained throughout the zoom range without color distortion at the edges of the subjects.
The USM (Ultrasonic Motor) ring uses ultrasonic frequency vibrations to allow high-speed autofocus response and almost silent. The pair of perfect maintenance stops the focusing lens group with precision and without excesses. The manual focus override is available without having to disconnect the AF system. The minimum focusing distance is 0.45m throughout the zoom range.
Super Spectra coatings
The Super Spectra lens coatings optimized and the design of the lens elements suppress flare and ghosting, which tends to occur more often with digital cameras due to reflection of the image sensor. Coatings also help achieve true color balance and increase contrast for vivid images provide high fidelity.
Nice background effect
An almost perfectly circular aperture helps to create an effect of uniform and pleasant background.
