Overview

The Neewer NW665-C E-TTL II Speedlite Flash is a feature-rich lighting solution built specifically for Canon EOS cameras. With a guide number of GN60 and flash output adjustable from 1/1 to 1/256 power, it delivers enough output for a wide range of shooting scenarios — from intimate portraits to event coverage. The flash supports TTL, Manual, and Multi (stroboscopic) modes, and its high-speed sync capability up to 1/8000s allows photographers to use wide apertures in bright daylight while still benefiting from flash fill. Additional professional features include flash exposure compensation, flash exposure bracketing, flash exposure lock, and first/second curtain sync, giving users fine-grained control over their lighting.

One of the standout features of the NW665-C is its built-in 10.8V 2040mAh rechargeable lithium battery, which delivers up to 650 full-power flashes with a fast 1.5-second recycle time. This eliminates the recurring expense and inconvenience of disposable batteries while providing consistent performance throughout a shoot. The integrated 2.4G wireless system supports 99 IDs across 32 channels with multi-group master and slave configurations, enabling complex multi-flash setups without additional accessories. The zoom head covers 20mm to 200mm in both auto and manual modes, and the flash head offers full 360° horizontal and -7° to 90° vertical rotation for versatile bounce and directional lighting. Compatibility spans a broad range of Canon bodies, and firmware upgradability provides a measure of future-proofing.
