Fringer's EF-FX: Canon EF lenses on Fujifilm X cameras
Fringer lists 86 Canon EF and EF-S lenses and 78 from Sigma, Tamron and others that it has tested and set up for the camera's phase-detection autofocus (firmware 3.10). On these, autofocus works in AF-S and AF-C; most other EF lenses work with contrast autofocus only, which is slower. Its camera list names 12 of the 13 Fujifilm X cameras here; the X-T30 III is not on it.
Fringer's EF-FX adapters fit Canon EF and EF-S lenses to Fujifilm X cameras with autofocus. Fujifilm does not make or support them; these are Fringer's own lists of the lenses and cameras it has tested, and what to set on the camera.

Fringer EF-FX Pro III
A ring on the adapter sets the aperture in third stops, like an XF lens, with an A position for the camera to choose. Brass mounts and a weather-sealed design. The Pro II before it works the same way and takes the same firmware.
A focal reducer: about 0.74 times the focal length and about one stop brighter, for full-frame EF lenses only. You set the aperture with the camera's dial.
On every camera on the list, a lens Fringer has set up focuses with phase detection at every focus point, Wide and Tracking included. Boost mode: Fringer's manual says the X-Trans IV cameras may then prefer contrast autofocus, and that the X-Trans V cameras have no such limit. Stabilisation: with a lens that has none, the camera's own works, and Fringer says it handles lenses shorter than 100 mm well. Fringer's page
Which lenses
Fringer's list for firmware 3.10 has 223 lines, a lens with a teleconverter counted as a line of its own: 86 Canon lenses and 78 from other makers. Canon's TS-E tilt-shift lenses also work, focused by hand, so Fringer leaves them off the list.

Teleconverters: Fringer tested Canon's EF 1.4X II and III and EF 2X II and III. Sometimes a lens from another maker is no longer recognised after its own firmware update; Fringer asks for a JPEG with its EXIF data and adds the lens in the next adapter firmware. Fringer's list
What carries across
Autofocus with the camera's phase detection, in AF-S and AF-C, on the lenses Fringer lists.
Stabilisation in IS lenses, switched by the camera's IS MODE setting.
The aperture, set by the adapter's ring on the Pro versions and by the camera's dial on the others.
The lens data in each file: the lens, its focal length and the f-number.
What to know first
Lenses not on the list: most work, with contrast autofocus only, which is slower; a few may not work until a later adapter firmware adds them.
EF-M lenses do not fit, and EF-S lenses do not fit the Ultra.
A small focus point uses contrast autofocus only: Fringer suggests the medium size.
The first time you mount a lens, the adapter may run its focus to both ends to calibrate it, and it always does for a lens not on the list. Leave the focus ring alone while it does.
Aperture noise: in aperture priority the lens's aperture moves as the light changes while you frame, with a small click. Setting the shutter speed yourself stops it.
Framing
On these cameras an EF lens frames 1.5 times tighter than its focal length: a 50 mm frames like 75 mm. Through the Ultra, the same 50 mm frames like about 56 mm (50 × 0.74 × 1.5), and an f/1.4 lens becomes about f/1.0.
Updating it
Fringer adds lenses through firmware updates; the current one is 3.10. There is one file for the Pro versions, one for the Ultra and one for the II: take the one for yours. Take the adapter off the camera, connect it to a computer through the USB port inside its lens mount with a cable that carries data, and copy the file to the drive named FRINGER. To see which version an adapter has, hold the camera's DISP button while you switch it on: the “Lens version” it shows is the adapter's firmware.
Facts from the makers' specification pages. How we check
Questions
Does the Fringer EF-FX autofocus on the X-T5?
Yes. Fringer's camera list names the X-T5, and the lenses on its list focus with the camera's phase detection at every focus point, in AF-S and AF-C.
Does the Fringer EF-FX work on the X-T30 III?
Fringer's camera list does not name it yet. That means Fringer has not listed it, not that it fails.
What is the difference between the EF-FX Pro III and the EF-FX II?
The Pro III has a ring that sets the aperture like an XF lens, brass mounts and a weather-sealed design. On the II you set the aperture with the camera's dial. Both take the same lenses.
Can I use EF-S lenses on the EF-FX?
Yes on the Pro and II versions; Fringer lists EF-S lenses it has set up. Not on the Ultra, whose glass is made for full-frame EF lenses: an EF-S lens may not mount, or may leave dark corners.
