Inon Underwater Semi-fisheye Conversion Lens UFL-G140 SD 

Ultra Wide Even Underwater

Though an action camera is equipped with ultra wide lens, its coverage underwater will dramatically narrow down due to different refraction ratio between air and water.

For example, maximum angle of view of GoPro® HERO11 Black is approx. 156° on land which will narrow down to approx. 94° when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UFL-G140 SD provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work only with action cameras.

Dynamic CFWA Imaging

Shooting through the INON UFL-G140 SD lens enables you to shoot a subject at close range to benefit deformed and/or perspective result.

The native depth of field (DoF) of the GoPro® HERO11 Black on land is approx. 60cm/2ft to ∞. With the INON UFL-G140 SD, DoF underwater will be extended to 4cm/1.6in to ∞ closer to camera side.

Professional-level Image Quality

The UFL-G140 SD is constructed of 4 elements in 4 groups. Rear element is made from high refractive index glass lens to minimize whole size dramatically without sacrificing performance. Front acrylic dome has five layers multi-coating on its inner surface providing as same grade of image quality as like optical glass dome at affordable pricing.
