GearScore™ Verdict — Which should you buy?
Professional Hybrid Shooters, Portrait & Wildlife — EOS R5 (2020): A landmark camera — 8K video and 45MP in one body set the standard for what mirrorless could be.
Portrait, Landscape & Studio Photography — A7R II (2015): The A7R II transformed the A7R series — adding IBIS, 4K video, BSI sensor tech, and phase-detect AF in one generation. A landmark Sony camera.
Who should buy what
