6. Operating Modes
The MK-14EXT-C offers several operating modes to suit different photographic needs:
- Manual Mode: Allows precise control over flash output. You can adjust the power level in 8 steps, with each step offering 3 fine-tuning adjustments. This mode is ideal for consistent lighting in controlled environments.
- E-TTL Mode: (Evaluative Through-The-Lens) Automatically adjusts flash output based on the camera's metering system. This mode simplifies exposure settings and is suitable for dynamic shooting conditions. Flash exposure compensation (FEC) can be adjusted in 1/3-stop increments.
- Multi Mode: Fires the flash multiple times during a single exposure, creating stroboscopic effects. Settings for flash frequency and number of flashes can be adjusted.
- LED AF Assist Lamp: Provides continuous light to assist the camera's autofocus system in low-light situations. This can be activated independently of the flash modes.
- Individual Lamp Control: The ring flash features two independent flash tubes (Lamp A and Lamp B). You can select to fire Lamp A only, Lamp B only, or both lamps simultaneously. This allows for creative lighting control, such as creating directional light for texture.
- Long Brightness Mode: Provides continuous LED light for video recording or as a modeling light.
