Description
- Upgraded Multifunctional Speedlite- NW645II-N Speedlite supports TTL, HSS (high-speed sync) up to 1/8000s, optical slave mode, stroboscopic flashes, 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 SD-9 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-N 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- The 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 Compatible with Nikon D4 D5 D6 D60 D70S D90 D100 D200 D300 D610 D700 D750 D780 D800 D810 D850 D3100 D3200 D3300 D3400 D3500 D5000 D5100 D5200 D5300 D7100 D7500 Z9 Zfc Z50 Z5 Z6 Z7 Z6II Z7II cameras
