Viltrox Unveils Spark Z3 Compact TTL Flash
Viltrox has introduced the Spark Z3, a compact TTL on-camera flash adopting a “cyber-inspired” design and featuring a matte metallic body with a translucent panel on the top that exposes part of the internal circuitry. The unit is available in gray and green, making it visually distinct in a segment usually dominated by neutral finishes.
The Spark Z3 measures 78.4 × 67.2 × 55.9 mm and weighs 144 grams: despite its small form factor, it delivers 26 watt-seconds of output, which is sufficient for close-range subjects, fill light or casual event photography. The guide number is 16 meters at ISO 100. While less powerful than larger or professional flash units, it maintains a one-second recycle time at full output, enabling continuous use in dynamic situations.
The device offers both TTL auto exposure and manual operation, with seven power levels ranging from 1/64 to full output. This provides entry-level accessibility while still allowing more experienced users to take control of the lighting. The color temperature is rated at 6,500 K ±200 K, with flash durations between 1/3000 and 1/30000 of a second. The unit also supports optical triggering with two slave modes (S1 and S2), which allows it to be integrated into multi-light setups.
Power comes from a built-in 1,800 mAh lithium-ion battery, capable of up to 650 full-power flashes on a single charge. Recharging is handled via USB-C in approximately 70 minutes. A snap-on diffuser is included, though it reduces output. The flash lacks a bounce and swivel head, meaning it is limited to direct illumination, and it does not feature a digital display.
The Spark Z3’s styling continues Viltrox’s move into accessories beyond lenses, following earlier releases such as the Vintage Z1 flash. Compared to that earlier model, which was manual only and featured a universal pin, the Spark Z3 adds TTL support for Fujifilm, Nikon, Canon, and Sony hot shoes.
The Spark Z3 is priced at around $55 (approximately €63 or £52). It is already available for Fujifilm (Z3-F) and Nikon (Z3-N) cameras, with Sony (Z3-S) and Canon (Z3-C) versions scheduled for release in the near future.
