(*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 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 on 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 on the housing without any adapter.

●Compact yet Wide 100 degree Coverage
•The compact lens body matches with compact MPK-HSR1 without 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 benefit of deep depth of field making minimum focusing distance underwater "96mm/3.8inch" (*7) enabling to shoot a subject at 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 powerful lens has more degradation on image corners. The UCL-G165 M55 is so-called wide close-up lens, so the lens can suppresses the aberration and enables more close-up image comparing standard close-up lens. Comparison images as below.

*All images are taken from 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/3.8in.
Lower left: With UCL-330 via step-up ring. Minimum focusing distance underwater is approx. 202mm/8.0in.
Lower right: With UCL-165 M67 via step-up ring. Minimum focusing distance underwater is approx. 135mm/5.3in.
