4.2. TTL (Through-The-Lens) Automatic Flash

In TTL mode, the flash automatically meters the scene to achieve accurate flash exposure, adjusting for complex lighting changes. This mode supports automatic zoom (28-105mm) and exposure compensation (FEC/FEB/FEL).

Manual mode allows for precise control over flash output, ranging from 1/1 to 1/256. This is ideal for controlled lighting environments or when consistent output is required.

4.4. Multi-Strobe Mode

The multi-strobe mode enables a series of rapid flashes within a single exposure, creating dynamic motion effects. Flash duration can be as short as 1/180s to 1/20000s.

4.5. High-Speed Sync (HSS)

The Z2-C supports 1/8000s HSS, allowing you to use flash at shutter speeds faster than your camera's native sync speed. This is particularly useful for overpowering ambient light outdoors or using wide apertures.

4.6. Front/Rear Curtain Sync

Synchronize the flash with either the opening (front curtain) or closing (rear curtain) of the camera's shutter for creative motion blur effects.

4.7. S1/S2 Optical Slave Modes

The flash can be triggered optically by another flash unit in S1 (standard slave) or S2 (pre-flash cancel slave) modes, providing off-camera lighting without a radio trigger.

4.8. Flexible Flash Head

The flash head can swivel 0-330° horizontally and tilt -7-120° vertically, allowing for bounce flash and precise light direction.

4.9. Modeling Lamps

The Z2-C features two upgraded 2W 3300K LED modeling lamps (one below the flash head) with 10 adjustable brightness levels (01-10). These lamps assist in visualizing light patterns and focusing in low light.
