Beschreibung

INON INC. is pleased to announce official release of “cage”, “semi-fisheye conversion lens” and “wide close-up lens” for GoPro® HERO3/3+ genuine dive housing (depth rating: 60m/197ft) on September 25th , 2014.

  • SD Mount Cage HERO3/3+ (*1)(*2) - needed to mount UFL-G140 SD or UCL-G165 SD and sold separately (not included with lens)!
  • UFL-G140 SD Underwater Semi-fisheye Conversion Lens (*3)(*5)
  • UCL-G165 SD Underwater Wide Close-up Lens (*4)(*5)

(*1) Compatible housing is genuine “Dive Housing (60m/197ft)”. The “Standard Housing (40m/131ft)” packaged with “GoPro® HERO3+” is not compatible. (“GoPro® HERO3” is packaged with the “Dive Housing”)
(*2) When using on land, set FOV mode other than [Wide] or use without the SD Mount Cage to prevent vignetting observed mainly in Ultra Wide mode even without an attachment lens. (No vignetting underwater)
(*3) Designed only for underwater use. (When using on land, distant subject is not in focus and angle of view is not as wide as rated)
(*4) Designed only for underwater use. (When using on land with FOV setting [WIDE], vignetting will be observed)
(*5) Not usable for [SuperView mode] of GoPro® HERO3+ Black Edition as this mode adds software-based deformation effect enhancing more aberrations when using an attachment lens.

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” 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.

UFL-G140 SD specifications (*10)

  • Size (including lens hood): φ93.4mm (3.7in) x 41.8mm(1.6in)
  • Weight (including lens hood): U/W: approx.153g (5.4oz) Air: 300g (10.6oz)
  • Mount system: INON SD Mount
  • Depth rating: 60m (196.9ft)
  • Material/surface finishing: Corrosion-resistant aluminum alloy/rigid black alumite, PC etc.
  • Lens material/coating: Optical glass/both side coating, Optical plastic/both side hard coating, inner multi-coating
  • Depth of field (*13): 10cm/3.9in~∞(GoPro® HERO3 Black Edition
    4cm/1.6in~∞(GoPro® HERO3+ Black Edition)
  • Lens construction: 4 groups 4 elements
  • Max. view angle (*14): 140.0°(underwater)

(*11) Measured angle of view by INON or calculated angle of view underwater based on the measured angle of view. 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 140°. (The “White Edition” has not been tested)
(*12) 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.
(*13) Measured distance underwater for GoPro® HERO3/HERO3+ Black Edition. Divide by 1.33 for visual distance underwater. Other Edition has not been tested.
(*14) Actual angle of view (actual field of view) varies among different shooting modes.
