EOS R7vs Z7 IIvs A7 III
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.
Landscape & Studio / High-Resolution — Z7 II (2020): The Z7 II is a landscape and studio camera first, everything else second. 45.7MP with weather sealing and dual card slots is a compelling package. If you need resolution, it delivers. If you don't, the Z6 II is the smarter buy.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
