Canon RF 28-70mm f/2L USM 70-28mm
Delivering a constant f/2 aperture across the entire 28-70mm zoom range, this lens effectively replaces multiple fast primes for low-light shooting and shallow depth of field control. Its robust, weather-sealed L-series build incorporates a customizable control ring and a ring-type USM motor for fast, silent autofocus. This lens is best for wedding and event photographers who need prime-like speed with the flexibility of a zoom in fast-paced environments.
