[Description]

■「UFL-G140 SD」 Underwater Semi-fisheye Conversion Lens■

  • Measured maximum angle of view of GoPro® HERO3/HERO3+ Black Edition is「approx. 151°(*11) on land」which will narrow down to「approx. 94°(*11)」when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UFL-G140 SD provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work as like using the camera on land.
  • Theoretically the depth of field (DoF) of the GoPro® HERO3/HERO3+ Black Edition on land is「approx. 60cm/2ft~∞」based on focal length/aperture of camera lens and pixel pitch of the image sensor. With the INON UFL-G140 SD, DoF underwater will be extended to「10cm/3.9in.~∞(*12)」/ GoPro® HERO3 or「4cm/1.6in~∞(*12)」/GoPro® HERO3+ enabling you to shoot at close range to benefit deformed result. (Other Edition has not been tested)
  • No vignetting even at FOV setting WIDE (Not compatible with GoPro® HERO3+ Black Edition “SuperView ゙ mode)
  • Bayonet INON SD Mount compatible to support friendly and speedy lens exchange underwater.
  • Optics is constructed of 4 elements in 4 groups. Rear element is made from high refractive index glass lens to minimize whole size dramatically without sacrificing performance.
  • The inner surface of the front acrylic dome has 5 layers multi-coating to deliver quality footage as like a glass dome at budget price.
  • M55 screw mount version will be released later.
