Sleek and versatile, the Canon RF 24-105mm f/4-7.1 IS STM is a well-rounded zoom covering wide-angle to short telephoto focal lengths to benefit working in a wide variety of conditions. A variable maximum aperture also helps to maintain an impressively compact profile to suit everyday shooting needs. Complementing the flexible design is a unique Center Macro Focus position, which enables working with close-up subjects at a 1:2 maximum magnification ratio, and an Optical Image Stabilizer also helps to achieve sharp imagery by minimizing the appearance of camera shake. Also, an STM motor affords impressively quiet and smooth autofocus performance and full-time manual focus override. Additionally, a configurable Control Ring lets you adjust exposure settings, including ISO, aperture, and exposure compensation, from the lens itself.
