The Viltrox Spark Z3 is a small TTL (Through-The-Lens) on-camera flash that offers advanced features, combined with a special "Cyber Mech" style, at an affordable price point. At only 144g, the Z3 features a palm-sized body (approximately 78×67×56 mm) that makes it perfect for travel and street photographers who want a lot of light but do not want a large flash.
The unit offers 26Ws of output power with a respectable 1-second recycle time at full power. It features both TTL auto-metering function (for almost instant exposure correction) and Manual mode, which allows for a total of seven levels of adjustable power (1/64 to 1/1), providing precise power adjustment. A built-in 1800mAh lithium-ion battery provides up to 650 full-power flashes on a single charge, and it can be recharged quickly through the USB-C port in approximately 70 minutes.
In addition to its on-camera function, the Spark Z3 offers S1 and S2 optical slave modes, enabling wireless off-camera flash synchronization with other flashes in configurations with even more lights. The intuitive dial-based control scheme minimizes confusing LCD screens, making it a great, stylish upgrade for practitioners moving beyond their camera's built-in flash.
