Lumix G9vs A7 III
VS
GearScore™ Verdict — Which should you buy?
Wildlife, Sports, Travel — Lumix G9 (2017): The G9 showed that Micro Four Thirds could compete for fast-action stills.
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.
