Advanced TTL Performance for Olympus & Panasonic: This compact lighting unit delivers full TTL support for Four Thirds & Micro Four Thirds cameras, enabling accurate automatic exposures, seamless high-speed sync, and both 1st and 2nd curtain sync. Photographers can rely on consistent, intelligent output whether shooting fast action, portraits, or dynamic low-light scenes. Flexible Remote Triggering System: This lighting unit includes an integrated control system that allows it to coordinate with compatible off-camera flashes for easy multi-light arrangements. It supports long-distance triggering, multiple groups, and intuitive remote adjustments without requiring direct line-of-sight. Powerful Output with Versatile Zoom Range: A guide number of 118' at ISO 100 (105mm position) ensures strong illumination for most shooting environments. The motorized zoom head covers 24–105mm, while the 14mm built-in wide panel supports ultra-wide lenses, providing excellent flexibility for everything from environmental shots to tight telephoto compositions. Full Bounce, Tilt & Rotation Control: The flash head tilts from –7° to +90° and rotates a full 270°, enabling complete control over directional light. Users can bounce light off ceilings, walls, and modifiers to create soft, natural-looking lighting effects instead of harsh direct flash—ideal for weddings, events, indoor portraits, and product photography. Fast Recycle Times & Efficient Power: Powered by two AA batteries (alkaline or NiMH), the unit delivers up to 210 full-power flashes with recycle times ranging from 0.1 to 2.2 seconds. Whether shooting in rapid bursts or pacing through a long photo session, performance remains quick, reliable, and consistent. Firmware updates are also supported via the USB port, ensuring long-term functionality.
