Verdictwhich should you buy?
GH5 — Video, Filmmaking & Hybrid Shooting: The GH5 redefined what a consumer video camera could do — 4K/60p and 10-bit 4:2:2 internal recording made it the independent filmmaker's tool of choice for years.
OM-D E-M5 III — Travel & Lightweight Outdoor Photography: The lightest weather-sealed MFT camera — compact, travel-friendly, and capable with 7.5-stop IBIS in a body that fits in a jacket pocket.
