If you could just have 1 lens, many photographers would select the upgraded EF 24-105mm f/4L IS II USM Lens from Canon due to its remarkably adaptable zoom range from large angle to short telephoto, a constant f/4 aperture, and an exceptional build quality be suitable an L-series lens. This version II of the admired lens makes enhancements to image worth through the use of a latest optical design with 4 glass-molded aspherical elements that helps to limit igniting in the images. Also, it uses an Air Sphere Coating to minimize flaring and ghosting.
A ring-type Ultrasonic Motor AF system offers quick and precise autofocus while integrated optical image stabilization can help recompense for about 4 stops of shutter rate, reducing the effects of camera tremble. This lens also provides a zoom lock button to prevent lens steal when not vigorously in use as well as an inner focus system. Full-time manual focus override is available for making modifications regardless of the AF mode. Furthermore, it has a curved 10-blade aperture diaphragm for even out of focus elements.

An Air Sphere Coating (ASC) has been applied to elements of lens to minimize backlit ghosting and flaring for maintained transmission of light and high contrast in powerful lighting conditions. A ring-type Ultrasonic Motor (USM), along with an inner focusing system, optimized AF algorithms and high-speed CPU, are employed to deliver quick, complete, and near-silent autofocus performance.
