Max Shutter speed
Sony A7c can shoot continuously at max speed of 10.0 fps
and has max shutter speed of 1/4000 sec
. A7c also has an electronic shutter which can shoot silently at max speed of 1/8000s
. 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 A7c doesn't have a built-in flash but it has a flash shoe for mounting external flashes.
Sony A7c features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. The AF system has 693 points to choose from. Sony A7c 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, A7c 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 A7c is a perfect feature for shooting portraits and is especially useful when fast lenses are used and the depth of field is very narrow.
