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.
Low-Light Video, Documentary & Available-Light Filmmaking — A7S II (2015): A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
