Its metal barrel gives the XF 18mm F1.4 R LM WR a familiar high-quality feel while its weight of 370g /0.81lb hints at the high status of the glass within its 68.8 x 75.6mm dimensions.
Should you wish to focus manually, you’re likely to find that the broad focus ring is within natural reach of your index finger and thumb as you support a camera such as the X-S10 or X-T4. The ring has a smooth action with enough tension to make subtle focus shifts easy with pressure from your finger.
It takes roughly a 180° rotation to adjust from the closest to the furthest focusing point. However, the mechanism is focus-by-wire and there are no physical stop points, you just see that the endpoint has been reached on the viewfinder or screen display.
As usual, the aperture ring is between the lens mount and the focus ring. This is marked in whole stops from f/1.4-16 with click-stops enabling the aperture to be adjusted in 1/3EV steps.
Like the recently announced (and reviewed) Fujinon XF 27mm F2.8 R WR and Fujinon XF 10-24mm F4 R OIS WR, the XF 18mm F1.4 R LM WR’s aperture ring has a lock button that comes into play when it’s set to the ‘A’ for automatic position. The lens can only be rotated away from the ‘A’ setting when the button is pressed. That’s very handy as it’s easy to rotate the ring accidentally if you’re gripping it as you raise the camera to your eye.
