Should you buy the Canon RF 15-35mm f/2.8 L IS USM Wide-Angle Zoom Lens?
The Canon RF 15-35mm f/2.8 L IS USM Wide-Angle Zoom Lens is the pro wide zoom for RF mount full-frame bodies at $2399. The constant f/2.8 aperture across 15 to 35mm holds exposure for video racks and event work, the 5-stop optical image stabilization combines with R5 or R6 II IBIS for up to 8 stops total stabilization, the 82mm filter thread matches the L trinity for screw filter compatibility, the Nano USM motor drives quiet AF for video, the dust and moisture sealing extends mount to front, and the 15mm wide end pulls in more frame than 16mm rivals for cramped interiors. The trade is the 840g weight that taxes a strap day for travel and the $2399 price that runs above the Sigma Art alternative.
