INON UCL-G165 SD Underwater Wide Close-up Lens (for GoPro Hero3/4)

Requires INON SD Cage Mount

The INON “UCL-G165 SD” underwater wide close-up lens enables you to shoot a subject from close range of the lens with deep depth of field thanks to GoPro®’s deep-focus characteristic.
Compatible model
HERO4
HERO3+
HERO3
Get Closer Minimum Focus Distance

A GoPro® camera is a deep focus camera which does not require focusing but prevents a subject gets in focus within 60cm/2ft range (air) in theory 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 GoPro® cameras based on its optical characteristic supporting closer minimum focus distance underwater enabling high magnification/close-up imaging. The depth of field (DoF) underwater will be 5cm/2.0in to 35cm/1.1ft for GoPro® HERO4/3+ or 7cm/2.8in to ∞ for GoPro® HERO3.

* 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”.

Ideal Angle of View for Macro Shooting

Maximum angle of view of GoPro® HERO4, HERO3+/3 Black Edition is approx. 151° on land which will narrow down to approx. 94° when the camera is housed in genuine dive housing and submerged due to different refraction index. The INON UCL-G165 SD slightly increases angle of view underwater to 110° to capture dynamic scene played by a subject as the lens frames subject larger than UFL-G140 SD which delivers ultra wide 140°.
※Measured angle of view by INON on land or calculated angle of view underwater based on the measured angle of view on land. 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 110°. The “HERO3+ White Edition” has not been tested.
Coverage by UCL-G165 SD
Professional-level Image Quality

Optics is constructed of 2 elements in 2 groups. All elements are made from high refractive index glass lens to minimize whole size dramatically without sacrificing performance. Both lens elements have anti-reflection coating on all surfaces to elicit combined master lens performance with less ghost/flare.

Depth of field (*1) 5cm / 2.0in to 35cm / 1.1ft (HERO4, HERO3+ Black)
7cm / 2.8in to ∞(HERO3 Black)
Lens construction 2 groups 2 elements

Focal length (*2) 165mm (underwater)
(*1) Measured distance underwater for GoPro® HERO4/HERO3+ Black/HERO3 Black. Divide by 1.33 for visual distance underwater. Other Edition has not been tested.
(*2) Standalone focal length of UCL-G165 SD and not combined focal length with camera’s master lens.

When using the UCL-G165 SD
* Designed only for underwater use. When using on land with FOV setting [WIDE], vignetting will be observed.
* Not usable when [SuperView™] of GoPro® HERO4/HERO3+ Black Edition is selected as this mode adds software-based deformation effect resulting from processing original 4:3 aspect ratio to 16:9 enhancing more aberrations when using an attachment lens. It would not recommendable to use [SuperView™] when using the UCL-G165 SD lens.
