INON Optics Supports SONY DSC-RX0 / MPK-HSR1 

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.

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" (*1) enabling to shoot a subject at closer distance.

Why UCL-G165 M55?
The DSC-RX0 carries wide 24mm fix lens (*2) 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.
 
(*1)Measured distance between a subject and lens edge when autofocus works underwater (in a tank).
(*2)Focal length based on 35mm film equivalent.
