GoPro HERO3 / HERO3+ is ultra compact and high quality video camera capturing dominant market share in wearable camera segment thanks to wide range of accessories and handy video editing application GoPro Studio in addition to camera’s performance.
However, when we bring GoPro camera underwater, angle of view narrows down dramatically due to different refraction ratio and subjects in close range (within approx. 60cm/2ft) are out of focus since GoPro camera is a deep focus camera (fixed focal length) which prevents it from using for macro imaging.
So INON have been studying, developing and finally released dedicated accessories including a semi-fisheye wet lens to deliver nearly same angle of view as on land, a wide close-up wet lens to deliver deep depth of field by slightly increasing angle of view and cage to hold these lenses and arm products.
These newly released products are designed to use mainly for GoPro cameras with enormously minimized body size to achieve unparalleled portability well beyond conventional camera system.
Also GoPro camera is a deep focus camera thus users do not have to struggle on focusing through dive mask underwater but concentrate on composition for unique shooting style.
Everyone can enjoy to edit their contents by GoPro Studio without any special technique.

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 ~ Infinity(*1) for GoPro HERO3 or 5cm/2.0in ~ 35cm/1.1ft(*1) for GoPro HERO3+ enabling high magnification/close-up imaging.
  • Measured maximum angle of view of GoPro HERO3/HERO3+ Black Edition is approx. 151°(*2) on land which will narrow down to approx. 94°(*2) 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° 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.

 

  1. 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.
  2. 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)
  3. Measured distance underwater for GoPro HERO3/3+ Black Edition . Divide by 1.33 for visual distance underwater. Other Edition has not been tested.
  4. Standalone focal length of UCL-G165 SD and not combined focal length with camera’s master lens.
