Installation Guide

1. Clean the Lens: Before attaching, wipe the lens front element with a microfiber cloth to remove dust.
2. Align Threads: Hold the filter protector by its edge and align the screw thread with that of the lens.
3. Screw On: Turn clockwise until snug. Avoid over‑tightening to prevent damage to the threads.
4. Check Alignment: Ensure the filter sits flush against the lens without wobble.

Care and Maintenance

• Use a soft, lint‑free cloth for routine cleaning. Avoid abrasive materials that could scratch the glass.
• Store in a dust‑free case when not in use to prevent accumulation of particles on the optical surface.
• Avoid exposure to extreme temperatures or direct sunlight for prolonged periods, as this may affect the coating integrity.

Benefits for Photographers

• Prevents Dust Accumulation: Acts as a barrier against airborne particles that could settle on the lens during shooting.
• Maintains Optical Clarity: Unlike some protective films, the glass filter does not degrade image sharpness or introduce flare.
