Which should you buy?
Beginner Fujifilm — X-A7 (2019): The most affordable X-mount entry — Fujifilm colour and film simulations with a large flip screen for beginners.
Sports, Wildlife & Hybrid Professionals — Nikon Z8 (2023): Z9 performance in a compact body — 45MP, 8K/60p RAW, and 20fps burst without the bulk or price of the flagship.
Adventure, Underwater & Outdoor Use — OM System TG-7 (2023): Waterproof to 15m, freezeproof and shockproof — the TG-7 is the most capable rugged compact for adventure and outdoor use.
