Offering a greater focal-length range and a more compact construction than other standard zooms, the EF 24-105mm f/4 IS USM is the ideal lens for the professional travel photographer.
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.
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.
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.
