Max Shutter speed
Leica Q2 can shoot continuously at max speed of 20.0 fps
and has max shutter speed of 1/2000 sec
. Q2 also has an electronic shutter which can shoot silently at max speed of 1/40000s
. 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 Q2 doesn't have a built-in flash but it has a flash shoe for mounting external flashes.
Leica Q2 features a Contrast Detection autofocusing system. The AF system has 49 points to choose from. Leica Q2 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
