Which should you buy?
Wildlife, Sports & Action — EOS R7 (2022): The EOS R7 is one of the most complete APS-C cameras ever made. It combines a class-leading resolution sensor with best-in-class IBIS, 4K/60p video, weather sealing and 15fps burst. For wildlife, sports and action photographers on an APS-C budget, nothing else comes close.
Hybrid Video & Action — Z6 III (2024): Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
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.
