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.
Astrophotography & Low-Light — A7S (2014): The original A7S pioneered the concept of a camera optimised entirely for low light. Its 12.2MP sensor has enormous photosites — extraordinary high-ISO performance that still holds up. Lacking IBIS and limited to 1080p internally (4K requires external recorder), it is a specialist tool. For astrophotography, event videography, or any scenario where light is genuinely scarce, it remains outstanding.
Who should buy what
DC-G100D (2023)
- Content creators who want better quality than a smartphone without the weight of a full-size camera

- G100 owners who want the upgraded phase-detect AF for better subject tracking
A7S (2014)
