Full details

It provides the essential benefit of flexible, on-camera lighting that assists with low-light autofocus and depth, though its GN8 power output is best suited for close-range subjects rather than large-scale studio photography.

Setup, Compatibility & Care

To set up the SL03, simply slide the unit onto your camera's hot shoe and tighten the locking dial to ensure a stable connection. For compatibility, the universal shoe fits the vast majority of DSLR and mirrorless cameras currently on the market. To maintain the device, ensure the hot shoe contacts remain free of dust and debris, as build-up can interfere with the connection. When not in use, store the unit in a cool, dry place and ensure it is powered off to prevent accidental discharge. Periodically charge the internal battery even if the unit is not frequently used to ensure the battery cells remain healthy.
