The Action head offers the fastest flash duration.
If you want to go with the ELB 400 portable battery flash, you'll have to choose between 3 flash heads: the Pro, the Action and the HS head.
The Action head offers the fastest flash duration to freeze moving subjects with the normal flash sync shutter speed of your camera (1/200th a second) without the use of Hi-Sync technology. When shooting with a Hasselblad or shooting with a DSLR at the standard sync speed or below, you should use the Action heads.
