The NW655S 2.4 GHz Wireless Flash Speedlite for Sony from Neewer features multiple modes of operation, including E-TTL mode, which lets you use the actual amount of light passing through the lens to determine the corresponding flash output. In manual mode, the speedlite provides 8-level light quantity control (1/128 to 1/1) for setting the flash brightness. S1/S2 mode lets you use your main light to control the sub light to flash. Also, with 1/8000 HSS, a continuous light source is produced in a short time, and the actual flash output varies according to the shutter speed.
