Which should you buy?
Commercial, Studio & Landscape Professionals — Fujifilm GFX 100S II (2024): 102MP medium-format quality in the most accessible GFX body — the best entry point to the Fujifilm GFX system.
Professional & Luxury Hybrid Shooters — Leica SL3 (2024): Leica's most capable mirrorless — 60MP, 30fps burst, 8K ProRes, and 7.5-stop IBIS with L-mount's growing lens ecosystem.
Professional Video & Low-Light Filmmaking — A7S III (2020): If video is your primary discipline, the A7S III is the camera. 4K/120p at 10-bit in a weather-sealed body with a 9.44M dot EVF is an extraordinary package. The 12MP sensor isn't limiting for video — and it's usable at ISO 409,600 in a pinch.
