Yes, the DJI Mic Mini works with the Fujifilm X100VI — with conditions (see below).
Fujifilm X100VI has a 2.5mm TRRS microphone/shutter release input. DJI Mic Mini has a 3.5mm TRS analog output. Requires a 2.5mm TRRS to 3.5mm TRS adapter — compatible when adapter is used, but the adapter is sold separately and not included with any of these mics.
Conditions for compatibility
Requires 2.5mm TRRS to 3.5mm TRS adapter (sold separately, not included with any of these mics)
