Employ through-the-lens flash exposure in your underwater photography with Ikelite's DL4 DS Link Fujifilm TTL Converter and FT1 Hot Shoe Kit. Faster, more accurate and more reliable than fiber-optic TTL triggers, this converter allows you to set exposure value compensation in your camera, and to switch between TTL and manual exposure with the simple click of a button. It supports rear curtain sync and improves your strobe's battery life and recycle time. This converter comes with a hot shoe that's compatible with the FUJIFILM X-T3 camera and Ikelite 200DL Housing #71503.
