Canon EF 24–105mm f/4L IS II USM is a professional standard zoom with constant f/4 aperture, compatible with full-frame and APS-C Canon EF cameras (38–168mm equivalent on APS-C). It offers excellent versatility for photo and video when lens changes are impractical. Air Sphere Coating minimizes flare and ghosting in backlit scenes. A rounded 10-blade diaphragm improves bokeh quality. Ring-type USM autofocus is fast and accurate, while optical IS compensates up to four stops of shake. A zoom lock prevents lens creep, and internal focusing supports full-time manual adjustment. Included: Canon EF 24–105mm f/4L IS II USM lens, front and rear caps, hood, pouch.
