Z3-S-Gray (for Sony)Gray 1

✓USB‑C recharging in about 70 minutes provides convenient on‑the‑go power management.

✓Built‑in lithium‑ion battery eliminates the need for external AA batteries or separate power packs.

✓Snap‑on diffuser allows softening of light while keeping the flash unit portable.

✓Unique cyber‑inspired matte metallic design with visible internal circuitry adds aesthetic appeal.

Cons

✗Low power output of only 26 Ws (GN 16 m) limits use to close‑range or fill lighting.
✗Fixed flash head with no bounce or swivel restricts lighting direction and diffusion options.
✗Absence of a digital display makes it harder to verify settings at a glance.
✗Using the snap‑on diffuser further reduces the already modest output.
✗Reported guide‑number inconsistencies (e.g., 0.9 m) create uncertainty about true performance.

✗Some users reported delivery issues unrelated to product quality.

Expert Opinion

Professional reviewers highlight the Spark Z3’s futuristic design, ultra‑compact size and fast 1‑second recycle as strong points, noting its reliable TTL and manual modes with 7‑stop control. They commend its optical slave capability and short flash durations for motion freezing, but consistently point out the limited power (GN 16 m) and fixed head as drawbacks for serious lighting work.

What Users Say

Everyday users repeatedly praise the flash’s tiny footprint, lightweight feel, built‑in battery and eye‑catching design, calling it a perfect pocket‑sized addition for casual shooting. Complaints are minimal, mainly concerning occasional delivery problems, while performance expectations align with its intended use as a portable fill light.

Common Complaints

Low output power, guide‑number inconsistencies, fixed head without bounce, and lack of a digital display are the most frequently mentioned issues.

How It Compares

vs. Godox TT350

Advantages

✓Higher guide number (GN 36) provides more illumination power.
✓Bounce head allows directional and softened lighting.
✓Similar 1 s recycle time.

Disadvantages

✗Heavier (≈200 g) and larger than the Spark Z3.
✗Requires external AA batteries or separate power pack.
✗No built‑in battery for on‑the‑go charging.

Choose Godox TT350 when you need more power and a bounce head, and size/weight are less critical.

vs. Yongnuo YN560‑IV

Advantages

✓Very high guide number (GN 58) for strong main lighting.
✓Bounce head offers flexible light shaping.
✓Manual control suitable for experienced users.

Disadvantages

✗Significantly heavier (≈350 g) and bulkier.
✗Uses AA batteries, lacking built‑in rechargeable power.
✗No TTL functionality, limiting automatic exposure.

Select Yongnuo YN560‑IV for high‑power, bounce‑head needs where weight and battery convenience are secondary.
