Max Shutter speed
Sony RX100 VI can shoot continuously at max speed of 24.0 fps
and has max shutter speed of 1/2000 sec
. RX100 VI also has an electronic shutter which can shoot silently at max speed of 1/32000s
. One thing to keep in mind is that electronic shutter may cause rolling shutter / jello effects, and also banding issues under artificial light on your images.
Unfortunately RX100 VI doesn't have an external flash shoe so you are limited with the built-in flash.
One neat feature that we like about RX100 VI's built-in flash has is that the flash head can be tilted upwards manually using your finger, which can be used to bounce the flash light and create a more pleasing lighting on your subject. It is not a very strong flash so the ceiling/wall or the surface you use for bouncing must be relatively close to the camera.
Sony RX100 VI features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. The AF system has 315 points to choose from. Sony RX100 VI also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
