( 2) Measured DoF from foreground of the lens surface. Divide by 1.33 for visual distance underwater.｡
( 3) Measured distance underwater for GoPro® HERO10 Black/HERO9 Black/HERO8 Black/HERO7 Black/HERO6 Black/HERO5 Black/HERO4/HERO3 Black/HERO3 Black/HERO/HERO /HERO LCD. Other Edition has not been tested.
When using the UCL-G165 SD The UCL-G165 SD is designed only for underwater use. Using the lens on land will have vignetting. When using for GoPro®
Always set camera's Field of View (FOV) to WIDE / Ultra Wide. Using Medium or Narrow won't bring optimal performance of this lens.
Not usable for SuperView™ as this mode adds software-based deformation effect resulting from processing original 4:3 aspect ratio to 16:9 enhancing more aberrations when using an attachment lens. It would not recommendable to use SuperView™ when using the UCL-G165 SD lens.
Since this lens provides ultra wide angle of view, it is recommended to set Spot Meter to ON when using external lighting source (LED flashlight.). Setting Spot Meter to OFF may have washout if the external lighting device aims center of the frame. When using for TG-Tracker
Activate image stabilization function of the camera while shooting video to avoid vignetting. When taking still images, do not use attachment lens to avoid significant vignetting on image corners.
Since the camera is designed to offer optimal focusing performance for close range subject, usable range of DoF (depth of field) with this lens is "2cm/0.8in to 15cm/5.9in" and distant subject beyond this range gets blur. When using for FDR-X3000/HDR-AS300
Select SteadyShot (Movie) Act when shooting video as Std and OFF cause slight vignetting. Select SteadyShot (Still) ON when shooting still image. Excessive camera movement may result vignetting even SteadyShot (Movie) Act is selected.
Always set camera's angle setting to W:Wide. Using M:Medium or N:Narrow won't bring optimal performance of this lens.
