Max Shutter speed
Sony A6100 can shoot continuously at max speed of 11.0 fps
and has max shutter speed of 1/4000 sec
A6100 has a built-in flash, and it also has a flash shoe to mount your external flashes too.
One neat feature that we like about A6100'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 A6100 features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. The AF system has 425 points to choose from.
Sony A6100 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically. In addition to the face detect AF, A6100 has a more sophisticated feature called Eye Tracking AF
which detects and locks focus to the selected eye of the person in the frame accurately and tracks as the subject moves. Eye tracking AF of Sony A6100 is a perfect feature for shooting portraits and is especially useful when fast lenses are used and the depth of field is very narrow.
