6.2 Aperture Control
The F1.8 maximum aperture allows for excellent low-light performance and beautiful background blur (bokeh). Aperture settings are controlled via your camera body. Consult your camera's manual for specific instructions on adjusting aperture.
6.3 Weather Sealing (Splashproof, Dustproof)
The lens boasts an IPX1 rating, making it splashproof and dustproof. This allows for shooting in light rain or dusty environments. However, it is not waterproof; avoid submerging the lens in water or exposing it to heavy rain.

The weather-sealed design of the lens allows for use in challenging conditions.
7. Maintenance

- For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optical lenses. Apply a small amount of lens cleaning solution to the cloth, not directly to the lens.
- Never use abrasive materials, solvents, or harsh chemicals to clean the lens.
7.2 Storage
- When not in use, attach both front and rear lens caps.
- Store the lens in a dry, cool, and well-ventilated area, away from direct sunlight and high humidity.
