Verdict: Yes — a simple 17.3 mm adapter keeps infinity focus.
What to expect#
Aperture control: lenses with a manual aperture ring work directly; electronically controlled lenses (no ring) need a smart adapter or one with a built-in aperture lever.
Focus: use focus peaking and magnification in the viewfinder. Exposure metering works normally because the camera meters through the lens at working aperture.

Frequently asked questions#
Will Canon EF lenses autofocus on Fujifilm G-mount?
No — adapted lenses are manual focus on this combination.
Does a Canon EF to Fujifilm G-mount adapter affect image quality?
A glass-free adapter is just a precisely machined spacer, so image quality is unchanged when it is built to the right thickness. Cheap adapters can be slightly too thin or thick, which shifts the infinity mark.
