Max Shutter speed
Fujifilm XQ1 can shoot continuously at max speed of 12 fps
and has max shutter speed of 1/4000 sec
Unfortunately XQ1 doesn't have an external flash shoe so you are limited with the built-in flash.
Fujifilm XQ1 features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. Fujifilm XQ1 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
