(*1) Specification is subject to change without prior notice.
(*2) UWL-H100 28LD performance itself (telescopic magnification: ν).
(*3) Actual angle of view may vary depending on your camera / housing.
(*4) Actual distance on land (=visual measurement underwater.) For actual dustance underwater, multiply1.33 and actual distance on land.
(*5) View of angle amd vignetting may vary deoending on combined housing model,even with same camera.
(*6) Slightly vignetting on corners at wide end. Slightly zoom to telephoto side or crop the image.
(*7) Vignetting information is based on when not using "image stabilizer function".
(*8) Actual distance underwater. For visual measurement, divide by 1.33.
(*9) Significant vignetting can be observed on image corners. Zoom to telephoto side.
(*10) Usable when preset focal length 28mm(35mm film equivalent) is selected by Step Zoom function.
(*11) Slight vignetting is observed at zoom position 28mm (35m film equivalent). Crop an image after shooting.
(*12) We recommend to deactivate image stabilizer of combined camera to avoid possible vignetting underwater.
(*13) When shooting, zoom towards to telephoto side at approximately focal length 28mm (35mm film equivalent) until no vignetting is observed.
