INON UCL-100LD Close-up Lens (+12 Diopter)

[Features]

• 3 elements in 3 groups lens construction effectively suppress aberrations comparing to 2 elements in 2 groups lens. Inner optical surfaces (four of them) have antireflection coating to successfully provide superior quality images with high resolution and high contrast.
• Larger lens aperture effectively suppresses vignetting even using at wide end 28mm (35mm film equivalent) (*1)
• The UCL-100 makes minimum shooting distance short both on land/underwater enabling to get closer to a subject for close-up/macro imaging
• The UCL-100 LD has lockable INON "28LD Mount" to support easy, speedy yet reliable installation on "28LD Mount Base" while the UCL-100M67 carries M67 screw mount to provide wide versatility.
• The lens barrel has joint screw mount on its front side to hold another INON M67 series close-up lens for super macro imaging (*2)(*3).

(*1) Using on land and zoom wide end setting will have vignetting. Crop an image after shooting or zoom in until no vignetting is observed.

(*2) When using add on "UCL-165M67" or "UCL-330", vignettig will be observed at zoom wide end underwater. Zoom towards telephoto side until no vignetting is observed.

(*3) Depending on combined camera/housing, stacking with other close-up lens could have significant degradation on image quality. For detail, please refer to "INON UCL-100LD/UCL-100M67 Compatibility Chart" linked in below section.

(*4) Focal length of  "UCL-100LD"/"UCL-100M67" standalone and not combined focal length with camera’s master lens.
