Special lenses enable the highest image quality across the entire focal length range with reduced visible distortions. The ASC coating (Advance Air Sphere Coating) minimizes lens reflections and stray light when shooting under unpredictable outdoor lighting conditions. The image stabilizer reduces the risk of motion blur, allowing for exposure times up to four stops longer. With a constant aperture of f/4, you can quickly switch between wide-angle, standard, and medium telephoto. The EF 24-105mm f/4L IS II USM is suitable for both photo and video recording, offering an ideal focal length range for a variety of subjects in a compact package. The modern autofocus enables smooth, professional-looking focus transitions, virtually silent focusing, and stable focus tracking with manual fine-tuning available at any time. The EF 24-105mm f/4L IS II USM features the new design of the L-series. Its robust construction provides enhanced protection against shocks and vibrations, making it capable of withstanding demanding professional use. Compared to its predecessor, the optical system of the EF 24-105mm f/4L IS II USM has been completely redesigned, offering even better resolution and higher sharpness from the center of the image to the edges. The newly developed image stabilizer allows for exposure times up to 4 stops longer, while the EF 24-105mm f/4L IS USM only provided 2.5 stops.
