Max Shutter speed
Nikon Z7 can shoot continuously at max speed of 9.0 fps
and has max shutter speed of 1/8000 sec
Unfortunately Z7 doesn't have a built-in flash but it has a flash shoe for mounting external flashes.
Nikon Z7 features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. The AF system has 493 points to choose from. Nikon Z7 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
Macro shooters will love Nikon Z7's Focus Stacking feature. In this mode, Z7 automatically composites multiple shots taken at different focal positions using focus bracketing to create a single image with maximum depth of field.
