2. Setup and Installation

This section provides general guidance for attaching and preparing your Fujinon XF 23mm F1.4 R lens for use. For detailed camera-specific instructions, please refer to your camera's user manual.

Attaching the Lens:

1. Ensure both the camera and lens are powered off.
2. Remove the rear lens cap from the Fujinon XF 23mm F1.4 R lens and the body cap from your Fujifilm X-Mount camera.
3. Align the white mounting mark on the lens barrel with the white mounting mark on the camera body.

3. Operating the Lens

The Fujinon XF 23mm F1.4 R lens offers both autofocus and manual focus capabilities, along with an aperture ring for direct control over depth of field.

Focusing:

• Autofocus: When the camera is set to autofocus mode, the lens will automatically adjust focus. The built-in high-torque DC coreless motor ensures fast and precise autofocus performance.
• Manual Focus: To engage manual focusing, pull the focus ring towards the camera body. This will reveal distance markings on the barrel. Rotate the focus ring to adjust focus manually. This feature is particularly useful for pre-focusing on fast-moving subjects or minimizing shutter lag.
• Depth-of-Field Scale: The lens barrel includes a depth-of-field scale, which can assist in understanding the range of acceptable sharpness at different apertures and focus distances.

Aperture Control:

The lens features a dedicated aperture ring, allowing for direct and tactile control over the lens's aperture. The seven round-edged aperture blades contribute to smooth and pleasing bokeh, even when shooting at medium apertures.

4. Maintenance and Care

Proper care and maintenance will ensure the longevity and optimal performance of your Fujinon XF 23mm F1.4 R lens.

• When using a lens hood, do not pick up or hold the camera using only the hood.
• Keep the lens signal contacts clean.
• Use a blower to remove dust and lint from the glass surfaces of the lens or filter.
• To remove smudges and fingerprints, apply a small amount of lens cleaner to a soft, clean cotton cloth or lens-cleaning tissue and clean from the center outwards using a circular motion, taking care not to leave smears or touch the glass with your fingers.
• Never use organic solvents such as paint thinner or benzene to clean the lens.
• Attach the front and rear caps when the lens is not in use.
• Store the lens and filter in cool, dry locations to prevent mold and rust. Do not store in direct sunlight or with naphtha or camphor moth balls.
• Keep the lens dry. Rusting can cause irreparable damage. Wipe off rain and water droplets immediately.
• Leaving the lens in extremely hot locations could cause damage or warping.
