Max Shutter speed
Panasonic GF8 can shoot continuously at max speed of 5.8 fps
and has max shutter speed of 1/500 sec
. GF8 also has an electronic shutter which can shoot silently at max speed of 1/16000s
. 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 GF8 doesn't have an external flash shoe so you are limited with the built-in flash.
Panasonic GF8 features a Contrast Detection autofocusing system. The AF system has 23 points to choose from. Panasonic GF8 also features Face detection AF
where it intelligently detects the faces in the frame and locks the focus automatically.
