Ok, this one is the fastest, but the most stupid one;) However it will take photo after a photo without any additional delay. What does it do - it just press shutter button again and again without any thinking.
In fact - it's not really intervalo
meter but should do, what you want
repeat
click("shoot_full")
sleep(10)
until false
PS. Note that for fast shooting you should disable RAW save. RAW save takes 1-2 sec., depending on camera and SD card.
PS2. DO NOT use camera continous mode, rather manual mode with single photo.
