The UFL-G140 SD provides wild wide underwater footage nearly same view angle as using action camera on land.

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 ∞. 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".

Speedy Lens Exchange by SD Mount

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.
