EOS RPvs Leica Q3vs A7 III
Which should you buy?
Entry Full-Frame Stills Photography — EOS RP (2019): An affordable gateway into the RF system. The RP makes sense as a stepping stone camera — if you're committed to Canon RF glass, this is the cheapest full-frame body to buy those lenses for. Just manage expectations on video and battery life.
Travel, Street & Premium Compact Shooters — Leica Q3 (2023): 60MP, Summilux 28mm, IBIS, and weather sealing — the Q3 is the ultimate fixed-lens camera for those who can justify the cost.
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.
