Viltrox has just released a new contender in the mini-flash market, and I tested the new Viltrox Spark Z3 TTL on-Camera Mini Flash ahead of its release. I was excited to add some fun back into my photography. What I didn’t expect was for this cool cyberpunk-looking mini flash to win me over so much that I can’t stop talking about it. In this review, I will demonstrate why, as I put this pocket-sized flash through its paces.
In the past year, there has been a huge resurgence of portraits featuring harsh direct flash to illuminate all manner of subjects, in styles reminiscent of the user-friendly point-and-shoot camera era. This look is often associated with the lo-fi photography movement, but this style can be carried forward today with better quality and better results when pairing external flash units with the capabilities of modern cameras. Whatever mirrorless or DSLR camera you shoot with, adding an external flash can elevate your shots in a number of scenarios.
Small Size, Big Impact
If you are a photographer who currently shoots with speedlights, you will find the Viltrox Spark Z3 tiny in comparison to anything else you have used before. Measuring 78.4 × 67.2 × 55.9 mm and weighing just 144 g, this certainly won’t weigh down your setup—in fact, you will hardly realize it is there. It is smaller than my strobe triggers! Don’t let its size fool you; with 26 Ws of power output (adjustable from 1/1 to 1/64) and a fast-enough 1-second recycle time, this mini flash delivers in a way that enables you to keep up with the action and add a punch to your portraits. Whether you’re shooting indoors or out, still or moving subjects, that edgy direct flash adds a vibrant pop of contrast to your images. It is, of course, perfect for portraits, but versatile enough to light up a range of subjects.

Solid Performance for Different Types of Shooter
With a color temperature of 6,500 K ±200 K and flash durations from 1/3000 s to 1/30000 s, the flash handles a range of diverse lighting scenarios and is capable of freezing fast motion. It offers Manual (M) mode for scenarios where precise control is required and TTL Auto (A) mode for ease. You can use this flash in conjunction with other lighting, thanks to the S1/S2 modes for triggering other units.
My daughter, a casual photographer, paired the Spark Z3 with her Fujifilm X-T10 for a lightweight setup that gave her shots a high-end polish. The battery takes just over an hour to fully charge and delivers a whopping 650 flashes at full power before needing to be recharged again, which is ideal for creators on the move.
I shot a few images of my nephews outdoors, and while TTL mode worked well, switching to Manual mode let me fine-tune the balance between sky and subject when needed. In the above image, I exposed for the background and used the Spark Z3 to illuminate my nephew, who was gracious enough to spare a few minutes of his time before going to play with friends. It used to be much easier to convince my nephews to sit for portraits, but now the Spark Z3 allows me to keep up with them, shooting at their pace in a way that feels informal and fun, which is perfect for capturing quick snaps with great quality that mark that milestone of growing kids. Once one nephew agrees, the younger is automatically on board too, and wanted to show off some of his football skills for his photos, which in turn allowed for a few posed portraits before he was on the move again.
Cyberpunk Style That Turns Heads
The Spark Z3’s Gunmetal Gray in a matte finish (green also available) and cyberpunk-inspired design make it a standout from anything else in its category on the market right now. Its sci-fi-styled silhouette, with a window to see the inner workings of the unit, adds to the excitement of the product. I photographed a few fellow photographers who couldn’t believe the quality at a comparatively low price point. My nephews thought it looked like a spaceship toy. Among creative communities and beyond, this little flash is setting up to be a conversation piece that makes shooting feel fresh and fun.
Budget-Friendly and Broadly Compatible
Available worldwide and priced modestly, the Spark Z3 really is a steal. Its rugged build, auto-sleep feature (after 15 minutes), and compatibility with Nikon Z and Fujifilm X (I tested the Fuji X version) make it a practical choice for portraits, some events, or content creation. A 5% launch discount runs from September 25 through October 1.
What I Liked
- User-friendly dial interface is great for creators who are new to flash control
- Affordable price point at $54.99 USD / €62.99 / £51.99 / $79.99 CAD / ¥9,800
- Compact and lightweight design
What Could Be Better
- Fixed flash head, with no tilt or swivel options—at this price point, though, I wouldn’t expect any tilting flash head
- A storage pouch would be a great inclusion
Why the Viltrox Spark Z3 Is a Must-Have
Shooting with the Viltrox Spark Z3 Mini Flash has felt like a renewed experience. This simple-to-use mini flash feels fun and experimental, allowing creators to join the current direct flash trend but with polished results thanks to the quality of the output that you’d expect from more expensive units. Its compact design, simple operating controls, and consistent performance, along with head-turning style, make this a hit for hobbyists, pros, and everyone in between. Would I buy it? In a heartbeat. I now have my eye on the Green version for my Nikon camera. I’m betting this will be a hot holiday gift for creators this Christmas too.
