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® HERO10 Black 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 action 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.

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® HERO10 Black on land is approx. 60cm/2ft to 8. With the INON UFL-G140 SD, DoF underwater will be extended to 4cm/1.6in to 8 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".

Split Easy for UFL-G140
The Split Easy for UFL-G140 SD is a rubber ring that attaches to the camera-side lens of the UFL-G140 SD to hold water between the lens and body for split shooting. When in use, the lens is removed and replaced on the body underwater to fill the space between the lens and body with water for a perfect split shot without two water lines in the image.. * Compatible combinations are GoPro®HERO8 Black/Protective Case/SD Front Mask for HERO8 and GoPro®HERO9 Black/Protective Case + Waterproof Case/SD Front Mask for HERO9. Cannot be used with other combinations, including other GoPro cameras. ** Please note that the "UFL-G140 SD" lens was originally designed for underwater use only and therefore cannot focus on distant land (air) objects when taking a split shot..
