Inon UCL-90 M67 Underwater Close-up Macro Lens +11

Inon UCL-90 M67 Underwater Close-up Macro Lens +11

The UCL-90 series is designed to use solely underwater to acquire a high-quality image from its compact body thanks to HR glass providing long working distance and widely supports from a macro lens for full-frame SLR system to a compact digital camera.

High Power +11 Close-up Lens
The maximum magnification when using this lens with 100mm range macro lens for a full frame SLR system is x2.23 (area ratio x4.98) which delivers middle power in between UCL-67 M67/UCL-67 LD (+15 diopter) and UCL-165M67/UCL-165 LD (+6 diopter). High power close-up lens with an underwater focal length of 90mm which is equivalent to +11 diopter.

Long Working Distance for Comfortability
While the UCL-90 delivers high magnification, it still offers long working distance. When using with 100mm range macro lens for an SLR system, working distance (from the front edge of the lens surface) is 69mm at minimum focusing distance.

High Quality All Focus Range
Optically designed sole use underwater to effectively suppress aberrations in all focus range to deliver high contrast and sharp images despite shooting distance.

HR Glass for Compact Body
Using HR glass makes lens size compact supporting a wide range of camera system from the 100mm range macro lens for SLR to compact digital camera. Also, compact lens body has less limitation of lighting enabling you to use a wide variety of lighting techniques.

Achromat Lens
The lenses consist of 3 elements in 2 groups and effectively suppresses chromatic aberration by using achromat lens inside. Also, anti-reflection coating on all lens surfaces suppresses flare/ghost.

Stack Another M67 Lens
Optional Lens Adapter Ring for UCL-67/90 allows stacking another INON M67 series close-up lens (UCL-165M67/UCL-330 on the front side of UCL-90 for even higher magnification.

Compatible with M67 Flip Adapter
Optional M67 Flip Mount Adapter for UCL-67/90 is available to replace with original M67/LD mount to attach the lens on flip lens holder from other manufacturers such as Nauticam flip holder etc.
