Inon UFL-G140 SD Underwater Semi-fisheye Conversion Lens

Estimated 2-4 Weeks Delivery Time


The Inon UFL-G140 SD Underwater Semi-fisheye Conversion Lens provides an ultra wide field of view for your GoPro Cameras. Due to water refraction, your GoPro camera significantly reduces the field of view and the UFL-G140 SD lens bring it back to 140° underwater. The lens is constructed of 4 elements in 4 groups. The rear element is made from high refractive index glass lens to minimize whole size dramatically without sacrificing performance. The front acrylic dome has 5 layers of multi-coating on the inner surface to provide the same image quality as glas domes at a fraction of the cost.
