Verdictwhich should you buy?
G9 II — Wildlife, Sports & Hybrid Mft Shooters: Phase-detect AF transforms the G9 II into a genuine MFT all-rounder — the best Lumix MFT camera for both stills and video.
S1 — Landscape, Studio & Professional Stills On L-Mount: Built like a tank with one of the finest viewfinders ever made — the S1 is the choice for photographers who prioritise build quality and IBIS over AF speed.
