The Sony A9 III’s global shutter eliminates rolling shutter entirely. Every pixel is read at the same instant, not sequentially. At 120 fps continuous shooting with no blackout, the camera captures a bird in flight at intervals of 8.3 milliseconds. The FE 200-600mm f/5.6-6.3 G OSS is the lens that makes this frame rate useful rather than theoretical — long enough to fill the frame with a subject at distance, stabilized well enough for handheld tracking.
