Canon RF 16-28mm f/2.8 IS STM Lens

The Canon RF 16-28mm f/2.8 IS STM is a fast and versatile ultra-wide zoom for Canon’s RF-mount full-frame mirrorless systems, offering a constant f/2.8 aperture, built-in image stabilization and a compact, lightweight design. Whether you’re shooting landscapes, architecture, travel, or video, this lens gives you high performance and professional-grade optics without the bulk of traditional “L-series” wide zooms. With 16 mm on full-frame you capture immersive ultra-wide scenes, while 28 mm gives more natural context for portraits or interiors — all the while benefiting from excellent stabilization and sharpness from edge to edge.

Key Features:

• Full-frame RF-mount ultra-wide zoom: 16-28 mm focal length. 

• Constant f/2.8 maximum aperture throughout the zoom range for better low-light and depth-of-field control. 

• Built-in Optical Image Stabilization (IS) rated up to 5.5 stops; up to 8 stops when paired with a body with in-body stabilization (IBIS) via Coordinated Control IS. 

• Compact and lightweight: approx. φ76.5 mm × 91.0 mm (retracted) and weight approx 445 g — making it very travel-friendly.

• Minimum focusing distance down to 0.20 m (20 cm) at 28 mm end, with maximum magnification up to 0.26x — great for close-up wide-angle shots. 

• Nine-blade circular aperture for pleasing bokeh and smooth rendering of out-of-focus highlights. 

• Robust build with dust- and drip-resistant design comparable to Canon’s L-series lenses. 

• Filter thread size: 67 mm, making accessory filters (ND, polarizers) easier to source.
