GearScore™ Verdict — Which should you buy?
Professional Video, Documentary & Hybrid Commercial Work — EOS R5 C (2022): Canon's R5 reborn for cinema — 8K RAW unlimited, Cinema EOS colour science, and 45MP stills in a 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
EOS R5 C (2022)
- Videographers and cinematographers who want Canon Cinema EOS quality in a compact, run-and-gun body
