GearScore™ Verdict — Which should you buy?
Professional Sports, Press & Wildlife Photography — D6 (2020): Nikon's final and finest DSLR — the D6 brought 105 all-cross-type AF points, 14fps, and built-in LAN to the F mount. The last word in optical viewfinder photography.
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.
