INON UCL-G165 II SD Close-up Lens

The INON "UCL-G165 SD" underwater wide close-up lens enables you to shoot a subject from close range of the lens to capture the subject larger in a frame.

FRONT MASK necessary for intall with a GoPro Housing (sold separately):

- FRONT MASK GOPRO HERO9/10/11/12

- FRONT MASK GOPRO HERO8

- FRONT MASK GOPRO HERO5/6/7

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 II 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 10cm/3.9in to 35cm/1.1ft when using the lens for GoPro® HERO12 Black supporting closer minimum focus distance underwater to capture wow photos/clips. To help us with the minimum focusing distance, INON has the Focus Stick accessory for the UCL-G165 II SD that indicates the minimum focusing distance (sold separately).

Ideal Angle of View for Macro Shooting

Maximum angle of view of GoPro® HERO12 Black is approx. 156° 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 II 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°.

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.

Quick lens exchange with SD bayonet

The lens mounts an INON SD Bayonet to allow quick and safe lens exchange underwater. Compatible with INON bayonet type AD lens holders to hold the lens when not in use. Also compatible with AOi QRS-02 bayonet system.

The INON SD Front Mask is necessary for mounting on GoPro cameras. (Also compatible with AOi QRS-02 bayonet system)
