The UCL-67 LD, underwater close-up lens is designed to deliver high magnification yet superior image quality with comfortable long working distance enabling easy lighting.
The UCL-67 LD close-up lens offers super macro imaging for compact digital camera systems supported by INON lockable bayonet mount INON "28LD Mount Base"/"Lens Adapter Base".

Compatible attachment
28LD Mount Base (*1) (*2)
LD Lens Adapter Base (*1) (*2)

(*1) Compact digital camera with maximum optical zoom 5x or less.

(*2) Only usable when the focal length is between 60mm and 100mm range at 35mm film equivalent. Beyond this range, there will be vignetting at the wide side and deteriorated image quality at the telephoto side.

Powerful magnification with focal length 67mm (+15 diopter). Maximum magnification of the UCL-67 with range of 100mm macro lens for full frame SLR is 2.76x (area ratio: 7.65x) at the minimum focusing distance. (*3)
 
While the UCL-67 delivers high magnification, it still offers long working distance. When using with 100mm range macro lens for SLR, working distance is 52mm (83.4mm from housing port surface) at minimum focusing distance (*3).
Together with its compact size, the lens supports friendly lighting even at minimum focusing distance.

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

 
The lens is consists of 4 elements in 3 groups using high refractive index glass to accommodate with a macro lens for full-frame digital SLR with compact body yet delivering high magnification and superior image quality.
 
Employing achromatic lens effectively suppresses chromatic aberration and anti-reflection coating on all surfaces suppresses flare/ghost. Designed sole use underwater to provide effectively suppressed aberrations in all focal range and unparalleled high quality image on any supported shooting range. (*4)

(*4) This product is designed for underwater use only. Using on land will have less magnification, distortion, vignetting etc..

 
Optional "Lens Adapter Ring for UCL-67" is attached on the M65 screw thread of the UCL-67 allowing to stack INON M67 series, "UCL-165M67"/"UCL-330" on the front side of the UCL-67 to support even higher magnification for super macro imaging needs. (*5)

(*5) Other higher magnification close-up lens, "UCL-100M67" and "UCL-67 M67" are not usable as those combinations will have significantly degrade image quality.

 
Lockable bayonet mount INON "LD Mount" compatible. Easy, speedy yet reliable installation on "28LD Mount Base"/"LD Lens Adapter Base" can be obtained.
 
Optional "M67 Flip Mount Adapter for UCL-67" is available to replace with original M67 screw mount to use the lens on a flip mount such as Nauticam flip lens holder etc. This adapter allows the UCL-67 to locate close to housing lens port.(*6) (*7)

(*6) Not compatible with a flip lens holder with 57mm or smaller inner diameter such as from SAGA.

(*7) Original lens mount is replaceable by a customer using precision Philips screw driver to unscrew fixing screws.
