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.
Landscape & Studio / High-Resolution — Z7 II (2020): The Z7 II is a landscape and studio camera first, everything else second. 45.7MP with weather sealing and dual card slots is a compelling package. If you need resolution, it delivers. If you don't, the Z6 II is the smarter buy.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
