INON Underwater Fisheye Lens UFL-G140, SD Front Mask
Product Details
This is an INON underwater fisheye lens for GoPro and its genuine front mask. It was used for diving, dolphin swims, and whale swims.
The front mask is compatible with GoPro HERO 9/10/11/12/13.
It shows signs of use, but it is in good working condition, so please purchase if you are looking for a reasonably priced option! Please check the photos for the condition.
I will include photos taken with the lens (cropped from video) for your reference. (Image 5) Attaching the lens makes the footage beautifully wide.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
