EOS R7vs Z6 IIvs A7 IV
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.
All-Round Full-Frame Photography — Z6 II (2020): The Z6 II is the Nikon most photographers should buy. It's balanced across every discipline — stills, video, autofocus, weather sealing — without overpaying for megapixels you don't need. The Z-mount glass is superb.
Portrait & Wedding Photography — A7 IV (2021): The full-frame portrait benchmark — 33MP, AI Eye AF, and exceptional skin-tone rendering in a pro-grade hybrid body.
