Sony a1 II Still Leads in Speed Despite a7R VI Advancements
The Sony a7R VI brings a higher 66.8MP stacked sensor, 30fps RAW bursts, and strong autofocus, but the a1 II remains unmatched for action due to its far faster sensor readout (sub-4 ms), near-global shutter performance, quicker AF calculations, and faster drive controls, plus a higher flash sync and faster shutter speeds. This keeps the a1 II relevant for speed‑driven work, while the a7R VI shines in high‑resolution landscapes and general use.
