4.1 Selector Dials
The i40C features two main selector dials for control:
- 기능 다이얼: Controls the flash mode (e.g., TTL, Manual, Wireless, Slave).
- 전원 다이얼: Adjusts flash output or exposure compensation depending on the selected mode.
표시기 lamps (A/B/C) illuminate to show the current adjustment position, providing clear visual feedback.
4.2개의 플래시 모드
- TTL(Through-The-Lens): Automatic flash exposure control. The flash output is determined by the camera's metering system.
- 수동 : Allows manual adjustment of flash power from full power down to 1/256.
- Wireless TTL: Enables off-camera flash control with compatible camera systems.
- Slave Mode (SF/SD): The flash can be triggered by another flash unit. SF (Slave Film) mode is for traditional flash, while SD (Slave Digital) mode is for digital pre-flash systems.
4.3 LED Video Light
The Nissin i40C includes an integrated LED video light. This light has 9 steps of output level adjustment, controlled via the power dial, and is suitable for close-distance illumination.
4.4 고속 동기화(HSS)
The i40C supports high-speed synchronization, allowing the flash to sync with shutter speeds up to 1/8,000 seconds. This feature is useful for freezing fast motion or using flash with wide apertures in bright conditions.
4.5 Soft Box Usage
The included soft box diffuser softens the flash output and reduces harsh shadows. Attach it to the flash head when a softer, more diffused light is desired, particularly for close-up fill-in flash.
