Overview & Features
Dual use (land/underwater) wide conversion lens specially designed for 28mm wide camera (35mm film equivalent). The maximum view angle is 100.8° underwater for wide imaging and 179 ° on land for fish-eye imaging. For super wide angle photography, add the optional Dome Lens Unit II for UWL-H100 to increase the field of view of UWL-H100 to 144.8 deg.
A wide angle lens is absolutely essential for shooting the big stuff like wrecks and whale sharks.

MAIN FEATURES
- Together with newly designed optical construction, using highly refractive optical elements provides larger effective diameter of the rear optical element in compact size to accommodate with latest camera model carrying larger image sensor and brighter master lens.
- Unique optical design allows to shorten minimum focal distance with ultra wide view angle thus effective for wide macro shot.
- Optional「Dome Lens Unit II for UWL-H100」further increases maximum view angle to 144.8 ° underwater for semi-fisheye imaging.
- Optical construction consists of 4 elements in 4 groups with coated optical glasses which effectively suppress optical aberrations and elicits master lens performance.
- Lens mount is highly versatile screw type「M67 Mount」t
- Two options (Type1/Type2) for various camera type to bring out optimum performance of master lens.
- Optional「M67 Screw Ring Set for UWL-H100 28M67 Type1」or「M67 Screw Ring Set for UWL-H100 28M67 Type2」makes it easy to modify original lens to other type.
- Directly screwed on a housing which has M67 lens ring.
- Like the Inon UWL-H100 28LD, the UWL-H100 28M67 uses highly refractive optical elements enabling a larger rear diameter optical element in a compact lens. This accommodates the latest compact camera models that feature brighter lenses, larger sensors, and wider field of views.
- A Type 2 lens can be converted to a Type 1 lens with a Type 1 screw ring set
(For Nauticam NA-XZ1 use the type 2 lens.)
