5. Manutenzione

5.1 Pulizia della lente

To maintain optimal image quality, keep the lens elements clean. Use a lens blower to remove dust, followed by a soft lens brush. For smudges or fingerprints, use a clean microfiber lens cloth with a small amount of lens cleaning solution. Avoid touching the lens elements directly with your fingers.

5.2 Conservazione

When not in use, store the lens with both front and rear caps attached in a dry, cool place away from direct sunlight and extreme temperatures. If storing for extended periods, consider using a desiccant to prevent mold growth.

5.3 Dust and Water Resistance

The lens is equipped with a dust and water-resistant rubber ring at the mount. While this provides enhanced protection against dust and light moisture, the lens is not fully waterproof. Avoid exposing the lens to heavy rain or submerging it in water.

6. Risoluzione Dei Problemi

6.1 Problemi di messa a fuoco automatica

• L'obiettivo non mette a fuoco: Ensure the lens is securely mounted on the camera. Check if the camera's focus mode is set to AF. Clean the lens contacts on both the lens and camera body.
• Slow or inaccurate autofocus: This can occur in very low light conditions or with subjects lacking contrast. Try using a brighter light source or focusing on a high-contrast edge. Ensure your camera's firmware is up to date.

6.2 Problemi di qualità dell'immagine

• Soft images: Ensure proper focus. Check if the aperture is set too wide (e.g., F1.8) for certain scenes, as lenses often perform optimally when stopped down slightly. Use a tripod for stability in low light.
• Vignetting or distortion: These are common characteristics of ultra-wide-angle lenses. Most modern cameras and post-processing software can correct these automatically or manually.

6.3 Obiettivo non riconosciuto dalla fotocamera

• Turn off the camera, remove the lens, and reattach it securely.
• Clean the electronic contacts on both the lens and camera body with a clean, dry cloth.
• Ensure your camera's firmware is updated to the latest version, as new lenses may require updated camera firmware for full compatibility.
