Lens Overview — Canon 28-70mm f/2.8 IS STM

The Canon RF 28-70mm F2.8 IS STM is a full-frame standard zoom lens built for Canon RF mount mirrorless cameras. Covering a 28-70mm focal length range, it delivers a constant maximum aperture of f/2.8 throughout the entire zoom range, making it a reliable choice for photographers who need consistent exposure and depth-of-field control whether shooting wide or at longer focal lengths. The lens supports both autofocus and manual focus operation, giving shooters flexibility depending on the situation.

Optical image stabilization is built in, helping to manage camera shake during handheld shooting. The 82mm filter thread is a standard size for lenses in this class, allowing compatibility with a wide range of circular filters. At 1,430g, this is a substantial lens, which is worth factoring in if weight is a consideration for your kit.

Designed specifically for the Canon RF mount, it is compatible with Canon's lineup of RF-mount mirrorless camera bodies. The combination of a standard zoom range, fast constant aperture, optical stabilization, and autofocus capability makes this lens a well-rounded option for portrait, event, travel, and general-purpose photography on Canon's mirrorless platform.
