Inon UCL-90 M67 & UCL-90 LD

The UCL-67 M67 / LD underwater close-up lens is designed to deliver high magnification yet superior image quality best suited to full frame SLR macro lenses of focal length 60mm – 100mm with comfortable long working distance enabling easy lighting. The lens also supports mirrorless as well as compact system.

(*1) This lens is designed solely for underwater use and using on land will not magnify a subject and will have distortion on image edge or or vignetting etc.

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 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 a SLR system, working distance (from front edge of the lens surface) is 69mm (*2) at minimum focusing distance.

(*2) Usable zoom range is between 60mm and 100mm (35mm film equivalent). Beyond this range, there will be vignetting at wider side and deteriorated image quality at telephoto side.

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 of shooting distance.

HR Glass for Compact Body

Using HR glass makes lens size compact supporting wide range of camera system from 100mm range macro lens for SLR to compact digital camera (*3).  Also compact lens body has less limitation of lighting enabling you to use wide variety of lighting techniques.

(*3) When using for AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED.

Achromat Lens

The lens is consists 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 to stack another INON M67 series close-up lens (｢UCL-165M67｣/｢UCL-330｣on the front side of UCL-90 for even higher magnification (*4).

(*4) This lens is designed solely for underwater use and using on land will not magnify a subject and will have distortion on image edge or or vignetting etc.

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 manufacturer 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 screw driver to unscrew fixing screws)
