INON UFL-G140 SD Underwater Semi-fisheye Conversion Lens

Measured maximum angle of view of GoPro® HERO & Black Edition is approx. 151°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 GoPro® cameras.

John Landa reviewed the Inon mount cage with the special INON lenses. He was enthousiastic. Read his review and enjoy his videos. 

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® HERO 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.

* DoF on land is based on focal length/aperture of camera lens and pixel pitch of the image sensor. DoF underwater is measured from "the forefront of the lens".

Professional level 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.

Speedy lens exchange
Bayonet INON SD Mount compatible to support friendly and speedy lens exchange underwater. Compatible with AD Lens Holder to hold a lens when not in use.
