GearScore™ Verdict — Which should you buy?
Professional Video, Filmmaking & Hybrid Shooters On L-Mount — Lumix S5 IIX (2023): The S5 II with ProRes RAW and 6K Open Gate — the most serious L-mount video tool in a portable, weather-sealed body.
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.
Who should buy what
Lumix S5 IIX (2023)
- Video professionals who need ProRes RAW output and 6K Open Gate in a portable L-mount body
