Max Shutter speed
Panasonic S1 can shoot continuously at max speed of 9.0 fps
and has max shutter speed of 1/8000 sec
. S1 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 S1 doesn't have a built-in flash but it has a flash shoe for mounting external flashes.
Panasonic S1 features a Contrast Detection autofocusing system. The AF system has 225 points to choose from. Panasonic S1 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
Macro shooters will love Panasonic S1's Focus Stacking feature. In this mode, S1 automatically composites multiple shots taken at different focal positions using focus bracketing to create a single image with maximum depth of field.
Panasonic S1 has a special Post Focus mode which uses its 4K video and focus bracketing features together to shoot and stack a burst of images into a single image which you can change the focus point on the LCD screen after it is taken.
