Features 1. Material: Crafted from optical tempered glass, this lens protector features advanced coatings including anti-reflection (AR), anti-fog, and hydrophobic layers. It also undergoes an extra hardening treatment to achieve a surface hardness of 9H approximately ten times harder than standard plastic protectors (typically around 1H). Highly durable and scratch-resistant, it ensures long-lasting clarity and protection. With a native light transmittance of around 95%, the AR coating further enhances it to over 98%, delivering sharp, true-to-life image quality. 2. Anti-Fog & Waterproof Protection: Coated with a hydrophobic layer, it achieves a water contact angle of 115 degree preventing water droplets from sticking to the lens. The anti-fog feature ensures clear performance in both cold outdoor environments and humid indoor settings. 3. Deformation-Resistant & High Temperature Resistant: Maintains stable performance even in high-temperature environments, resisting warping or damage, and making it reliable for all-weather use. 4. Installation: Features a user-friendly twist-lock design for fast and tool-free installation and removal. You can quickly attach or detach the lens protector without hassle, saving time and allowing you to focus more on shooting. 5. Portability: Weighing only 8.3g (net) and 44.3g (with packaging), the lens protector is compact and lightweight. It fits easily in your pocket or camera bag, offering convenient, on-the-go protection without adding bulk. Package List 1. Protective lens x 2 2. Alcohol cotton x 2 3. Instruction manual x 1
