GiAi Magnetic Neutral Density Filter ND16 4 Stops for iPhone 17 Pro/Pro Max - Lens Protector phone Camera Accessories [REQUIRES Case SOLD SEPARATELY]

1-Second magnetic quick release – use only with the GiAi phone case. The powerful magnetic system allows you to attach and remove the ND filter one-handed in just one second, ensuring you never miss a fleeting moment. ND16 Optical Performance - Reduces the aperture by 4 diopters to achieve a slow shutter effect: blur flowing water, smoothing crowds or reaching a shallow depth of field with a large aperture in bright light. This magnetic ND filter evenly reduces the amount of light entering the lens, allowing you to extend the exposure time of your mobile device. Ideal for capturing creative effects such as flowing water or streaks of light that are difficult to achieve with your phone's default camera settings. Optimal stability: Strong magnetic attachment resists daily movement and light vibration. Even in hands-free shooting or outdoor travel, the filter stays securely in place, avoiding frame shifts or interruptions caused by loose filters. Strong Scene Adaptability: Especially suitable for outdoor photography (such as landscapes, flowing water and street photography) and video creation (such as vlogging and time-lapse), it easily captures professional effects like silky flowing water, dynamic blurry crowds and blurred backgrounds, improving the quality of mobile photography.
