INON Wet Lenses for GoPro® Cameras

 

While an action camera delivers ultra wide angle to capture unique realistic scene, angle of view underwater narrows down dramatically due to different refraction ratio between air and water.
For example, when GoPro® HERO10 Black is submerged, angle of view will narrow down to 94° making it difficult to benefit action camera’s ultra wide angle imaging. Also subjects in close range (within approx. 60cm/2ft in theory for HERO10 Black) are out of focus since majority of action cameras is a deep focus camera (fixed focal length) which prevents it from using for underwater macro imaging.
The INON “UFL-G140 SD” underwater semi-fisheye conversion lens provides nearly same wide coverage as using action camera standalone on land to enjoy capturing wild marine scene.
The INON “UCL-G165 SD” underwater wide close-up lens enables you to shoot subject from close range of the lens to capture the subject larger in a frame.

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.

Get Closer Minimum Focus Distance

An action camera is a deep focus camera which does not require focusing but prevents a subject gets in focus in close range (within 60cm/2ft range in theory for GoPro® camera) thus not usable for underwater macro shooting. Using standard macro lens for a compact digital camera would not help the situation as it would create vignetting and very shallow depth of field preventing comfortable focusing. The UCL-G165 SD lens is so-called “wide close-up lens” specifically designed for action cameras based on their optical characteristic. The depth of field (DoF) underwater will be 5cm/2.0in to 35cm/1.1ft when using the lens for GoPro® HERO10 Black supporting closer minimum focus distance underwater to capture wow photos/clips.

* The depth of field (DoF) on land is theoretical value 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”.
