NEEWER Upgraded NW645II TTL Flash Speedlite

Description

• Upgraded Multifunctional Speedlite– NW645II Speedlite supports TTL, HSS (high speed sync) up to 1/8000s, optical slave mode, stroboscopic flashes, flash exposure compensation, rear curtain sync, and other features. A high guide number (GN58, ISO100m) allows lighting from a longer distance. A clear LCD screen displays all the information you need for precise settings
• Premium Flash Output– Flash output is adjustable from 1 to 1/128 in 1/3 increments according to the actual ambient light. 0.1-3.5s short recycle time and 1/300-1/20000s flash duration let you capture every transitory moment. An CP-E4 external charging port is available to speed up the recycling. Stable 5600K±200K daylight delivers a consistent color temperature to all shots
• Rear Curtain Flash Sync– NW645II supports rear curtain sync in which flashes burst at the end of exposure and freeze movements in the meantime. With this useful feature at hand, you can easily achieve a well illuminated photoshoot with smooth, expressive motion trails
• Optical Slave Control – It is compatible with original master flash units and can be activated when set on the same channel and group. Also supports S1 & S2 modes, where it can be triggered when the master units are in the manual mode and TTL mode, respectively
• Flexible Bounce Angles– Flash head can swivel up and down between -7° and 90° and rotate 270° to bounce the light off a wall and help you get natural photographs with fewer shadows. The diffusers and reflector create a broad and diffused output with less harsh shadows
