GearScore™ Verdict — Which should you buy?

Entry To Full-Frame Mirrorless & Rf Lens Exploration — EOS R (2018): The RF mount's founding camera — 30MP, Dual Pixel CMOS AF, and the proof-of-concept that launched Canon's mirrorless era.

Professional Sports, Wildlife & Action Photography — A9 (2017): The camera that changed professional photography — the A9's 20fps blackout-free burst and silent shutter proved mirrorless had definitively surpassed the DSLR.
