EOS R6 Mark IIvs Lumix S5 IIvs A7 III
Which should you buy?
Portraits & Action — EOS R6 Mark II (2022): 40fps burst, 8-stop IBIS, and Canon's best-in-class Dual Pixel AF — exceptional for action, sports, and portrait work.
Hybrid Video & Photography — Lumix S5 II (2023): Phase-detect AF changed everything for Lumix — the S5 II delivers exceptional hybrid performance with 6K video and genuine full-frame value.
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.
