Which should you buy?

Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.

Professional Video & Hybrid Shooting — Lumix S5 (2020): The S5 is an outstanding video camera that also takes excellent stills. 10-bit 4K/60p, dual native ISO and 6.5-stop IBIS in a weather-sealed body is a compelling package. The contrast-detect AF is its main weakness vs Sony and Canon — but for controlled shooting it doesn't hold it back.

Street Photography & Urban Reportage — Ricoh GR III (2019): The purest street photography compact — APS-C sensor, 28mm perspective, IBIS, and cult-favourite JPEG rendering in a shirt pocket.
