Sony a7R VI: Speed vs Shadow Detail, Tested

There's a real tradeoff buried in the a7R VI's spec sheet that Sony's marketing doesn't lead with. The improved shadow performance is genuine — that dual-readout trick works — but it only fires when the mechanical shutter is in play. The moment you tap into e-shutter for the fast burst rates Sony is selling this camera on, you trade some of that shadow headroom back. For landscape and architecture shooters on a tripod, this is a clean win over the a7R V. For anyone who bought the 'faster and better DR' pitch and plans to run e-shutter at a stadium or in a dark reception hall — the improvement is measurable in a lab, not in your actual files.
