The verdict
Choosing between these optics involves a $500 price gap and a trade-off between the f/1.2 maximum aperture of the prime and the 70-200mm focal range of the zoom.
Choose Canon RF 50mm F1.2L USM if you prioritize extreme low-light performance and shallow depth of field, as its f/1.2 maximum aperture is significantly wider than the zoom. This prime lens is the definitive choice for photographers needing maximum light gathering capabilities.
Choose Canon RF 70-200mm F2.8L IS USM if you require handheld stability while shooting distant subjects, utilizing its 5-stop optical image stabilization system. This zoom provides the necessary reach and stabilization for versatile event photography where subject distance varies.
