The Canon RF 28-70mm F2 L USM is an exceptionally versatile standard zoom lens that maintains a constant f/2 maximum aperture throughout its entire 28-70mm focal range. This rare combination of wide focal length coverage with professional-grade speed makes it an ideal choice for photographers seeking premium image quality across multiple shooting scenarios, from wide environmental shots through to flattering portrait perspectives. Built on Canon's advanced RF mount platform, this L-series lens features ultra-low dispersion glass elements and a ring-type ultrasonic autofocus motor for fast, quiet focusing with full-time manual override. The customisable control ring allows you to adjust exposure settings directly from the lens, whilst Air Sphere Coating minimises lens flare and ghosting for clean, distraction-free results. As a secondhand lens, this is an excellent opportunity to acquire premium Canon optics at considerable savings.
