Ultra Wide Even Underwater


Measured maximum angle of view of GoPro® HERO4/HERO3/HERO3+ 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.
* Measured angle of view by INON or calculated angle of view underwater based on the measured angle of view. Not confirmed by camera manufacture. The measured angle of view of “HERO3+ Silver Edition” is approx. 142°(air) which is less wide than the “Black Edition”. So angle of view underwater with this lens is less than 140°. The “HERO3+ White Edition” has not been tested.
angle of view 140°
 
Dynamic CFWA Imaging


Theoretically the depth of field (DoF) of the GoPro® HERO4, HERO3+ and HERO3 Black Edition on land is approx. 60cm/2ft to ∞. With the INON UFL-G140 SD, DoF underwater will be extended to 4cm/1.6in to ∞ for HERO4/HERO3+ or 10cm/3.9in to ∞ for HERO3 enabling you to shoot a subject at close range to benefit deformed and/or perspective result.
* 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". Other Edition has not been tested.

 
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.
