Inon Releases Two Attachment Lenses for RX0 in Sony Housing
By Joanna Lentini, February 9, 2018 @ 11:15 AM (EST)


 

Inon has released both a modified Wide Conversion Lens (UWL-100 28M55) and Wide Close-up Lens (UCL-G165 M55) for Sony’s uber-compact, shockproof, and waterproof DSC-RX0 digital camera. The lenses are intended for use on the original Sony MPK-HSR1 underwater housing as it comes equipped with a 55mm filter mount which works with the new lenses. When attached directly to the front of the housing, shooters will be able to produce wider and closer stills and video.

For prices, check with your local dealer.

(*1) Contact Sony Marketing Inc. for detail of camera/underwater housing. INON Inc. confirms product compatibility based on a camera available in Japan.

(*2) Vignetting is observed on land but underwater will not have vignetting.

(*3) The Dome Lens Unit II for UWL-100 is NOT compatible due to vignetting.

(*4) This lens is the M55 screw mount version of current UWL-100 28AD instead of the original bayonet mount. Please contact your local dealer if you wish to replace original bayonet mount of the UWL-100 28AD with this M55 screw mount.

(*5) Designed for underwater use only. Vignetting is observed on land but underwater will not have vignetting.

(*6) This lens is the M55 screw mount version of current UCL-G165 SD instead of original bayonet mount. Please contact your local dealer if you wish to replace original bayonet mount of the UCL-G165 SD with this M55 screw mount.


UWL-100 28M55 Wide Conversion Lens Product Features

  • Attached Directly to the Genuine Underwater Housing MPK-HSR1
    The lens mount is same M55 screw mount as filter screw of the MPK-HSR1 enabling you to attach the lens directly to the housing without any adapter.
  • Compact yet Wide 100-Degree Coverage
    The compact lens body matches with compact MPK-HSR1 without burden to provide handy wide imaging. The lens increases coverage dramatically to maximum 100-degree coverage underwater.

  • Dramatically Shorten Minimum Focusing Distance
    Minimum focusing distance of the DSC-RX0 on land is 50cm/1.6ft which will be extended at x1.3 underwater due to reflection ratio underwater. By attaching this lens, minimum focusing distance underwater will be shorten to 118mm/4.6in (*7) to enable you to take a Close Focus Wide Angle (CFWA) image.
  • Lens Hood II for UWL-100 28AD is compatible
    Optional Lens Hood II for UWL-100 28AD is usable to block unnecessary light coming from outside of lens coverage to suppress flare/ghost. 


UCL-G165 M55 Underwater Wide Close-up Lens Product Features

  • Attached Directly on the Genuine Underwater Housing MPK-HSR1
    As same as the wide lens, the lens mount is same M55 screw mount as filter screw of the MPK-HSR1 enabling you to attach the lens directly on the housing without any adapter.
  • Wide Close-up Lens with Deep Depth of Field
    The optics design widens the coverage slightly to have the benefit of deep depth of field making minimum focusing distance underwater 96mm/3.8inch (*7) enabling to shoot a subject at a closer distance.
  • Why UCL-G165 M55?
    The DSC-RX0 carries wide 24mm fix lens (*8) and its superior optical characteristic to have less aberrations creates pincushion aberration (concave center part) underwater. This aberration gets more significant with standard close-up lens and the powerful lens has more degradation on image corners. The UCL-G165 M55 is so-called wide close-up lens, so the lens can suppress the aberration and enables more close-up image comparing standard close-up lens. Comparison images as below.

*All images are taken from the same distance to compare distortion (pincushion aberration). 
 

Upper left: Without lens. Minimum focusing distance underwater is approx. 65cm/2.1ft. Upper right: With UCL-G165 M55 Minimum focusing distance underwater is approx. 96mm/3.8 in. Lower Left: With UCL-330 via step-up ring. Minimum focusing distance underwater is approx. 202mm/8.0 in. Lower right: With UCL-165 M67 via step-up ring. Minimum focusing distance underwater is approx. 135mm/5.3 in.
