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.
Professional Sports, Wildlife & Action Photography — A9 (2017): The camera that changed professional photography — the A9's 20fps blackout-free burst and silent shutter proved mirrorless had definitively surpassed the DSLR.
