BurstThe fastest frames per second the maker quotes. Top speeds often use the electronic shutter and may limit autofocus. Higher helps for sports, wildlife and kids.30 fpsBEST10 fps
StabilizationIn-body stabilisation. Each stop lets you shoot at half the shutter speed without blur, so 8 stops means very steady handheld shots.8.5 stopsBEST5.5 stops
ShutterFastest mechanical and electronic shutter speeds. The silent electronic shutter can freeze faster motion, but may bend fast subjects on slower sensors.1/8000 mech · 1/32000 elec1/8000 mech

Rolling shutterHow fast the sensor reads out, measured in lab tests. Slower readout bends fast-moving subjects and quick pans in video and electronic-shutter photos; under 10 ms is very good.16.5 ms · 8K full width, CineD26.8 ms · 4K full width, CineD
