Inon Announces New Versions of UWL-95S Wide Conversion Lens

Inon has released two new versions of its classic UWL-95S XD-mount wide conversion lens—one with a 52mm threaded mount and the other with a 67mm threaded mount. Like the original lens with its XD bayonet mount, the UWL-95S M52 and UWL-95S M67 lenses offer a maximum angle of view underwater of 95°, which can be optionally increased to 141° by adding Inon’s Dome Lens Unit III. (This dome comes in two types: glass and acrylic.)

The conversion lenses are designed for cameras with built-in lenses that are 24mm (equivalent) at their widest, such as the Olympus TG-6 or Sony RX100 V. As Inon shows in its press release below, the Olympus PT-059 housing for the former has an M52 mount, while the Sony MPK-RX100A housing for the latter has an M67 mount.

The UWL-95S M52 and UWL-95S M67 are shipping now. Contact your nearest Inon dealer for pricing information.

INON UWL-95S M52/M67 Wide Conversion Lens

We are pleased to announce new additions of UWL-95S wide conversion lens series, available to order from December 3rd, 2022.

The newly released UWL-95S M52 and UWL-95S M67 lenses now have the same lens barrel as the existing UWL-95S XD.

This design feature allows budget lens type conversion among three different lens mounts (M52, M67 or XD) only by changing the lens mount*.

*Optional lens mounts (M52, M67, XD bayonet) are available to purchase separately.

Other fundamental feature remains as UWL-95 series including:

  1. Maximum view angle 95° underwater/159° in air.
  2. Optional Dome Lens Unit IIIA/Dome Lens Unit IIIG further increases view angle underwater up to 141°.
  3. Optimally designed optics effectively suppresses flare/ghost even in backlit condition to provide sharp and high quality image.
  4. 1.0 inch type sensor with bright master lens camera compatibility.
  5. Minimum focusing distance 0 cm both on land and underwater.
