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.

High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.

Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
