The verdict
The primary trade-off between these professional zooms is a $400 price difference and the fundamental choice between a standard 24-70mm focal range and a telephoto 70-200mm reach.
Choose Canon RF 24-70mm F2.8L IS USM if you require a versatile walk-around lens with a shorter 125mm physical length and a dedicated control ring for tactile settings. This lens also offers a superior 5-stop optical image stabilization system for stable handheld shooting.
Choose Sony FE 70-200mm F2.8 GM OSS II if your work demands long-range compression and the smooth bokeh provided by its 11 aperture blades. Its 4 XD Linear Motors ensure rapid tracking for distant subjects, justifying the higher $2799 investment.
