PHOTO
Resolution20.4 MP26 MPBEST
SensorMegapixels and sensor size. Full-frame gathers more light than APS-C or Micro Four Thirds, for cleaner low-light shots and more background blur.Micro Four ThirdsAPS-C
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 fpsBEST11 fps
StabilizationIn-body stabilisation. Each stop lets you shoot at half the shutter speed without blur, so 8 stops means very steady handheld shots.7.5 stopsBEST5 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 elec1/4000 mech · 1/8000 elec
AutofocusWhat the camera recognises and tracks automatically, and how dark it can get before focus struggles (lower EV is better in low light).PeoplePeople, animals, birds, insects, vehicles, aircraft, trains · down to −3 EV
VIDEO
Best 4K frame rateThe fastest 4K frame rate. 60p and above lets you slow footage down smoothly, and 120p gives 5× slow motion.4K 30p4K 120p
Crop at 4K 60pWhether 4K 60p uses the full sensor width. A crop makes your lens act longer, so wide shots get harder.No 4K 60pNone, full width
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.10 ms · 4K full width, DPReview15.9 ms · 4K full width, CineD
Colour depth10-bit records far more colour detail than 8-bit, so footage holds up when you grade it. Worth it if you edit video.8-bit 4:2:010-bit 4:2:2
