GearScore™ Verdict — Which should you buy?
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
Professional Sports, Wildlife & Photojournalism — A9 II (2019): The A9 II polished the A9's groundbreaking formula — 20fps blackout-free, improved subject tracking, and a LAN port made it the professional sports standard.
