Canon's new RF16-28mm is a less expensive F2.8 zoom
The 16-28mm F2.8 becomes Canon's fourth wide-angle option, sitting between the $550 RF 15-30mm F4.5-6.3 IS STM and the $1400 RF 14-35mm F4 L IS USM. The new lens has better weather-sealing than the variable aperture zoom but, is less well-sealed than the slower-but-wider F4 'L' series lens. Above all of these sits the $2400 15-35mm F2.8 L IS USM.
