UCL-67 M67
UCL-67 LD


Product Features:

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) (*2) 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 (*2) at minimum focusing distance.

High Quality All Focus Range

Optically designed sole use underwater(*1) 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 (*3). 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 (*4).

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. (*Not compatible with any flip lens holder with 57mm or less diameter such as SAGA etc. Use the lens as it is without using this optional M67 Flip Mount Adapter for UCL-67/90) (*Original lens mount is replaceable by a customer using precision Philips screwdriver to unscrew fixing screws)
