GearScore™ Verdict — Which should you buy?
Vlogging, Content Creation & Lightweight Travel — DC-G100D (2023): The lightest capable MFT mirrorless for vloggers — phase-detect AF, directional audio, and the full Lumix lens ecosystem under 350g.
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
DC-G100D (2023)
- Content creators who want better quality than a smartphone without the weight of a full-size camera

A7 III (2018)

- Anyone who shoots in low light regularly
- Hybrid shooters needing both stills and video performance
