What We Like
+Constant f/2.8 aperture throughout zoom range with excellent low-light and depth-of-field control
+Compact and lightweight design—smallest and lightest RF zoom lens at 445g, ideal for travel and gimbal work
+Exceptional sharpness comparable to or exceeding L-series lenses despite non-L designation
+Impressive optical IS with 5.5 stops correction solo or up to 8 stops coordinated with IBIS
+Fast, silent STM autofocus with smooth video performance and focus breathing correction
+Weather-sealed construction matching L-series durability standards at a lower price point
Worth Knowing
−Limited focal length range (16-28mm) lacks the extra reach of competing 16-35mm or 15-35mm zooms
−Requires in-camera digital distortion correction—native barrel distortion of ~8.2% at 16mm relies on software correction
−Retractable barrel design adds minor inconvenience and durability concerns for frequent extension/retraction
−Lens hood not included in box; must be purchased separately as optional accessory
