Changing Aperture/Iris on Fuji Cameras with Mode Dial

The X-A series, X-M series and X-T100 have a mode dial on the top plate of the camera. Set to A mode or M mode and use the command dial to manually set the aperture/iris. To have the camera choose the aperture/iris value automatically, set to S or P.

 

Changing Aperture/Iris on Fuji Cameras without Mode Dial

The X-Pro, X-T (except X-T100/X-T200) and X-E series do not have a mode dial on the top plate of the camera. Under the 'Wrench' tab, Button/Dial Setting, Aperture Setting, choose 'AUTO' to always have the camera choose the aperture/iris value automatically, 'MANUAL' to always choose your own aperture/iris value using the command dial, and 'AUTO+MANUAL' to use the command dial to change the aperture/iris manually until the dial is turned beyond the minimum aperture/iris and the camera will switch to automatically choose the aperture/iris value. The camera will display 'P' or 'S' instead of 'A' or 'M' when it is choosing the aperture/iris value automatically.

 

Using a Cinema Lens with Manual Iris

You may choose between T-stop display or F-stop display by pressing MENU => 'Wrench' tab => SCREEN SETTING => Page 2 => APERTURE UNIT FOR CINEMA LENS. Choose T NUMBER or F NUMBER.

Note:

  1. Your cinema lens must have electronic contacts to transmit iris position. Ordinary lenses do not transmit T-stop data and they always show the F-stop.
  2. At the time of writing T-stop display is an exlusive feature of CINE Speed Booster ULTRA and CINE Smart Adapter. It will come to the non-CINE variants at a later date by firmware update.

 

Auto Iris

We recommend against uing auto iris/aperture during video capture. EF mount lenses adjust iris in 1/8th stop steps which may result in visible disruption in the footage or oscillation of the iris. Use A (Aperture Priority) or M (Manual) exposure modes.
