UCL-G165 SD Underwater Wide Close-up Lens - Inon Wet Macro (Close-Up) Lens. This lens will mount on top of a standard camera lens in order to magnify the subject and allow you to fill the frame with it while maintaining sharp auto focus. This lens is also compatible with Gopro Hero 8 and 9, you just need to add SD Front Mask for HERO9 (IN-4562121439948) or SD Front Mask for HERO8 (IN-4562121439931)

  • 1 x UCL-G165 SD Underwater Wide Close-up Lens
Top Product Features:
  • A GoPro is a deep focus camera preventing a subject gets in focus within 60cm/2ft range in theory thus not usable for underwater macro shooting. By using this lens, minimum focus distance underwater will be shorten; the depth of field (DoF) of camera will be 7cm/2.8in~8(*15) for GoPro HERO3 or 5cm/2.0in~35cm/1.1ft(*15) for GoPro HERO3+ enabling high magnification/close-up imaging.
  • Measured maximum angle of view of GoPro HERO3/HERO3+ Black Edition is approx. 151 Deg(*16) on land which will narrow down to approx. 94 Deg(*16) when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UCL-G165 SD is a unique close-up lens providing slightly wide angle of view underwater 110 Deg to have deeper DoF benefitting you with less out-of-focus close range clip which is not possible with standard close-up lens.
  • Bayonet INON SD Mount compatible to support friendly and speedy lens exchange underwater.
  • 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.

(*15) Measured from “the forefront of the lens” as rated DoF data of GoPro® HERO series is not available preventing to calculate theoretical DoF of this lens.
(*16) Measured angle of view by INON 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 “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 “White Edition” has not been tested)
(*17) Measured distance underwater for GoPro® HERO3/3+ Black Edition . Divide by 1.33 for visual distance underwater. Other Edition has not been tested.
