Convenient dual use (land / underwater) wide conversion lens in compact size. The maximum view angle is 105°underwater for wide imaging and 179°on land for fish-eye imaging.
Unique optical design allows to shorten minimum focal distance with ultra wide view angle thus effective for wide macro shot.
Optical construction consists of 4 elements in 4 groups with coated optical glasses, which effectively suppress optical aberrations and elicits master lens performance.
Bayonet "AD Mount" compatible to support instant installation and speedy lens exchange underwater.
The UWL-105AD is attached on compatible camera / housing via "AD Mount Base" which is exclusively designed for each housing.

(*1) Specification is subject to change without prior notice.
(*2) Including lens protector.
(*3) UWL-105AD stand-alone performance (telescopic magnification: v)
(*4) Slight vignetting on image corners. Crop the image or slightly zoom to telephto side.
(*5) Extremely minute vignetting part in one of image corners at wide end may be observed when using [UWL-105AD] underwater.
(*6) Vignetting possibility to be examined.
(*7) Actual distance on land (=visual measurement underwater). For actual underwater,multiply 1.33 by actual distance on land.
(*8) View of angle and vignetting may vary depending on housing type, even with same camera.
(*9) No vignetting. When using open aperture or near to open aperture, light amount may be insufficient at image circumference which can be suppressed by stepping down camera's aperture.
(*10) Vignetting information is based on when not using "image stabilizer function".
(*11) When using S50/S45/S40/S30 + WP-DC300. Actual view angle may vary depending on camera / housing
