Which should you buy?
Collectors, Fine Art & V-System Users — Hasselblad 907X & CFV 100C (2023): An engineering icon — the 907X + CFV 100C bridges Hasselblad V lenses from 1957 with a 100MP digital back in a form that is unmistakably Hasselblad.
Travel & Lightweight Outdoor Photography — Olympus OM-D E-M5 III (2019): 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.
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.
