The A7 V keeps the same 33 MP full-frame resolution as the A7 IV but adds a partially stacked sensor and a new BIONZ XR2 processor with AI — enabling blackout-free 30 fps bursts (vs 10 fps), far better autofocus, and up to 7.5-stop IBIS stabilization (vs ~5.5). Video gets stronger too, with oversampled 4K60 and 4K120 options and improved battery life.
