Operating the Lens

Aperture Control

The GF45mmF2.8 R WR lens features an aperture ring with marked f-stops from F2.8 to F32, and an 'A' (Auto) position. It also includes a 'C' (Command Dial) position. When the aperture ring is set to 'A', the camera automatically controls the aperture. When set to 'C', the aperture can be adjusted using the camera's command dial, allowing for flexible control based on photographer preference.

Autofocus and Manual Focus

This lens supports both autofocus (AF) and manual focus (MF). The focus mode can be selected via the camera body. For autofocus, ensure the camera's focus mode is set to AF. For manual focus, set the camera's focus mode to MF and rotate the focus ring on the lens to achieve desired sharpness. The lens features internal focusing, meaning its length does not change during focusing.

Weather Resistance

The GF45mmF2.8 R WR lens is designed with weather and dust resistance, making it suitable for use in various outdoor conditions, including temperatures as low as -10°C. While resistant, it is recommended to avoid prolonged exposure to heavy rain or extreme conditions. Always ensure the lens is properly mounted to a weather-sealed camera body for optimal protection.

Maintenance and Care

Cleaning the Lens

• Lens Elements: Use a blower brush to remove dust and debris. For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optics, along with a small amount of lens cleaning solution. Wipe gently in a circular motion from the center outwards.
• Lens Body: Wipe the lens barrel with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using organic solvents like thinner or benzene.
• Fluorine Coating: The front element features a fluorine coating, which repels water and dirt, making it easier to clean.

Storage

When not in use, store the lens with both front and rear caps attached in a cool, dry place away from direct sunlight and high humidity. If storing for extended periods, consider using a dehumidifying cabinet or silica gel packets to prevent mold and mildew growth.

Troubleshooting

Common Issues and Solutions

• Lens not recognized by camera: Ensure the lens is securely mounted to the camera body. Turn the camera off and on again. Clean the lens and camera electrical contacts with a dry, soft cloth.
• Autofocus not working: Check that the camera's focus mode is set to AF. Ensure there is sufficient light and contrast in the scene for the autofocus system to operate effectively.
• Image quality issues (e.g., blur, softness): Verify that the lens elements are clean. Check camera settings such as shutter speed and ISO to avoid motion blur or noise. Ensure proper focus.
• Lens not responding: Turn off the camera, remove the battery, wait a few moments, then reinsert the battery and turn the camera back on. If the issue persists, consult the camera's instruction manual or Fujifilm support.
