The INON UCL-G165 II ZD underwater wide close-up lens enables you to shoot a subject from a close range of the lens to capture the subject larger in a frame.
INON's popular “SD Mount Lens” among both amateur and professional action camera shooters expands its lineup with the new “ZD Mount Lens”. The ZD Mount Lens offers broad compatibility to shoot in full frame 8:7 aspect ratio of GoPro as well as to use with an action camera with larger and quality image sensors.
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 ZD 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.
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".
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 ZD slightly increases angle of view underwater to 110° to capture dynamic scene played by a subject as the lens frames subject larger than UFL-GR140 ZD which delivers ultra wide 140°.
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.
Bayonet INON ZD Mount compatible to support friendly and speedy lens exchange underwater. Compatible with ZD Lens Holder to hold a lens when not in use.
