This compact power zoom uses the camera menu for OIS and a command dial for aperture. X-S20’s +MOTION option depends on exposure settings.

Physical connection
SupportedXC15-45 is a native lens for X-S20’s Fujifilm X mount.
- Digital Fujifilm X mount; no adapter; not the historical film-camera X mount.
Stabilization
SupportedThe lens’s OIS is controlled by the camera menu and X-S20 also has sensor-shift stabilization. +MOTION variants can adjust shutter speed for detected movement.
- Use still-photo IS MODE; +MOTION has no effect at fixed ISO and may be unavailable with other settings.
- The X-S20 manual recommends IS MODE OFF for a tripod.
- No sum of lens and body stop ratings is claimed.
Aperture control
SupportedUse X-S20’s front command dial to choose aperture with this lens: f/3.5 maximum at wide angle, f/5.6 at telephoto, and f/22 minimum.
- Exposure mode A or M.
- Aperture control can be reassigned to the rear command dial.
Focus aids
LimitedThe camera’s focus-distance display is only a guide with XC15-45.
- The lens manual warns that the displayed value can differ from actual distance.
- Its specified focus range is measured from the focal plane, not the lens front.
Not covered by the sources
- Exact-pair stabilization effectiveness and any firmware minimum for the cited menu behavior remain unverified.
- No power-zoom speed, AF tracking performance or smooth aperture-transition guarantee is inferred.
