GearScore™ Verdict — Which should you buy?
Wildlife, Sports & Hybrid Mft Shooters — Lumix G9 II (2023): Phase-detect AF transforms the G9 II into a genuine MFT all-rounder — the best Lumix MFT camera for both stills and video.
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.
