O-Ring for Dome Lens Unit III

Successfully delivers underwater angle of view approx. 141° when using with a digital camera equipped with a large (i.e. 1.0 inch) image sensor. Smaller size comparing to the previous Dome Lens Unit II. The Dome Lens Unit IIIA Using High Transparency Optical Acrylic Material High transparency and lightweight optical acrylic dome provides quality image on a level with that of optical glass dome. Acrylic is better tolerated than polycarbonate to discoloration by inevitable ultraviolet rays outdoors or scratches during long-term usage assuring underwater use. The acrylic version is budget-friendly so would be good choice for those thinking to start wide angle photography. Optical Multi-coating Dramatically Improves Performance in Backlit Situation Both acrylic and glass version are finished with optical multi-coating which suppresses flare/ghosting effectively when shooting in bright and clear water or using back lighting technique to produce clear and quality images with appropriate contrast. Maximum Underwater Angle of View 141° The UWL-95 C24’s native underwater coverage approx. 95° will further increase to approx. 141° by installing the Dome Lens Unit III. A compact digital camera equipped with a large 1.0-type image sensor fitted with this optical combination enables to deliver vivid wide angle imaging as like an action camera without vignetting. *Rated angle of view is approximate value. No Vignetting at Zoom Wide End 24 mm Comparison shots by Sony DSC-RX100M5A at wide end (24 mm) Dome Lens Unit II Dome Lens Unit III The Dome Lens Unit III is optimally designed for a compact digital camera equipped with a large 1.0-type image sensor enabling to shoot at wide end 24mm/f1.8 without vignetting. Compatible with a water-proof camera equipped with standard 1/2.3-type image sensor as well to shoot without vignetting at zoom wide end 25mm. No need to zoom in or change camera zoom setting not to have vignetting as like previous models. Minimum Focusing Distance 0cm As same as the UWL-95 C24 wide lens, a combination with the Dome Lens Unit III keeps same minimum focusing distance 0cm.* Both Close Focus Wide Angle (CFWA) imaging just in front of a subject or wide imaging to capture broad seascape are possible through the same lens combination. *At zoom wide end Usable with All Zoom Range Usable throughout all zoom range.  For confirmed usable camera/housing click here Selectable Dome Material When Repairing Either acrylic or glass material is available when purchasing. The dome material is replaceable one to another when repairing based on usage or budget as both material use same dome lens barrel.

The Dome Lens Extension IIIG uses a multi-coated optical glass lens that provides high image quality under all shooting conditions. Dome lens extensions features a multi-coated optical dome element that effectively suppresses flare/ghost images and provides a sharp image with stable contrast even when shooting in bright and clear water. Installing this super wide-angle option on the UWL-95 C24 increases the underwater angle of view to approximately 141° and reduces the focusing range at a minimum focusing distance of 0 cm to bring the subject into focus on the lens surface. Verdict: Superior ultra-wide dome lens suitable for a wide range of shooting conditions, not only for wide seascapes but also for Close Focus Wide Angle (CFWA). The dome lens extensions IIIA and IIIG use the same lens tube, so that other dome material can be used if necessary (e.g. when replacing damaged original dome material). NOTE: The IIIA/G dome lens unit must be used with the UWL-95 C24 series underwater lens and cannot be used as a standalone lens.
