Maintenance Tips

• Lens Cleaning: Use a blower to remove dust, then gently clean the lens elements with a microfiber cloth and lens-safe solution to prevent smudges and scratches.

• Storage: Store the lens in a cool, dry place with both front and rear caps on. Utilizing a padded case offers additional protection against dust, moisture, and physical impacts.

• Built-in Lens Hood: The lens features a built-in lens hood to reduce flare and protect the front element. Ensure it's clean and free from obstructions to maintain optimal image quality.

• Moisture Protection: While the lens is designed with weather sealing, it's advisable to avoid excessive exposure to moisture. If the lens becomes wet, promptly dry it with a soft cloth and allow it to air dry completely before storage.

• Image Stabilization (IS): The lens is equipped with optical image stabilization. For best results, enable IS during handheld shooting, especially in low-light conditions. When using a tripod, it's recommended to disable IS to prevent potential feedback loops that might affect image sharpness.

• Regular Inspection: Periodically examine the lens for signs of wear, such as loose components or debris around the control rings. Addressing issues early can prevent potential damage and maintain the lens's performance.
