Overview

The Neewer NW635 is a TTL-capable speedlite designed specifically for Sony MI hot shoe mirrorless cameras, covering a broad compatibility range from the A7 and A9 series to the A6000 line and select RX models. It offers three core flash modes—TTL for automated exposure, Manual with 22 output levels from 1/128 to full power (with ±0.3EV fine-tuning), and Multi mode for stroboscopic effects. Optical slave modes S1 and S2 are also available for off-camera triggering. The motorized zoom head covers 24mm to 180mm and can be set to track your lens focal length automatically in TTL mode or adjusted manually for precise light control.

With a guide number of 58 meters at ISO 100 and 180mm zoom, the NW635 provides ample power for most indoor and moderate outdoor shooting scenarios. The flash head offers full bounce flexibility, tilting from -7° to 90° vertically and rotating -90° to 180° horizontally. It maintains a stable color temperature of 5600K ±200K for consistent results. A PC sync jack enables wired off-camera triggering, and the integrated 1/4" threaded base allows direct mounting on light stands for use with softboxes, color gels, and other Bowens S-type accessories. Overheating protection is built in to safeguard the unit during extended shooting sessions. At approximately 400g, the NW635 is lightweight and portable, powered by four AA batteries.
