FAQ:
1. Why I need this microphone cable adapter
----This is specially designed for select Fujifilm cameras, as some of the Fujifilm cameras have a 2.5mm mic jack instead of a standard 3.5mm mic jack, while most of the camera microphones sold in the market are with 3.5mm TRS mic jack, if you want to use these microphones with 3.5mm TRS jack, you need to get this mic audio adapter, otherwise, you will have to get the OEM Fujifilm microphone with 2.5mm TRS jack.
2. Where is the 2.5mm mic jack of the X-T3
----It is the 2.5mm remote socket on your camera, as a matter of fact, the 2.5mm remote socket on some of these Fujifilm cameras is also a microphone socket. So both a mic and remote go into this 2.5mm socket.
3. Does it work with the Fujifilm X-T4
----It does not work with the Fujifilm X-T4 as this camera already has a 3.5mm (1/8 inch) TRS female mic jack. As a matter of fact, other Fujifilm cameras such as Fujifilm X-T3, X-T2, X-H1, X-E4, X-S10, X-T200, GFX 50R, GFX 50S and GFX 50S II don't require the need of this mic audio adapter, you can use a microphone with standard 3.5mm TRS jack on these cameras directly.
4. Does it work with the Canon Rebel T7
----No, it does not work with any Canon camera, this mic cable adapter is only designed for selected Fujifilm cameras, though there is a 2.5mm socket on this camera, it is for the use of a remote shutter cord instead of a microphone.
5. I have a microphone with TRRS jack (4 poles), is it compatible with this mic cable
----No, it is not compatible. Your mic with TRRS jack is designed for smart devices such as phone and tablet with a 3.5mm TRRS female headphone jack, since the 3.5mm female mic jack on this cable adapter is a TRS type (3 poles), if you want to use your existing mic with this mic adapter cable on your Fujifilm camera, you need to extra buy a 3.5mm male TRS to 3.5mm TRRS female adapter.
