Product features

• 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. Also compatible with compact/mirrorless digital cameras. (*1)
• The UCL-67 is an ultra-high magnification close-up lens with underwater focal length 67mm (equivalent to +15 diopter) delivering maximum magnification 2.76x (area ratio: 7.65x ) when using for 100mm range macro lens for SLR at the minimum focusing distance. (*2)
• Designed sole use underwater to provide unparalleled high quality image as underwater close-up lens and effectively suppress aberrations in all focal range considering it ultra high magnification.
• 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(*2). Together with its compact size, the lens supports friendly lighting even at minimum focusing distance.
• Employing achromatic lens effectively suppresses chromatic aberration and anti-reflection coating on all surfaces suppresses flare/ghost.
• Optional Lens Adapter Ring for UCL-67 allows to stack another INON M67 series close-up lens (UCL-165M67/UCL-330on the front side of UCL-67 for even higher magnification (*3).
• The UCL-67 M67 has M67 screw mount to provide wide versatility.
• The UCL-67 LD is to use for lockable INON 28LD Mount Base and LD Lens Adapter Base to support easy, speedy yet reliable installation.
• Optional M67 Flip Mount Adapter for UCL-67 is available to replace with original M67/LD mount to attach the lens on flip lens holder from other manufacture such as Nauticam flip holder etc.
  (Not compatible with any flip lens holder with 57mm or less diameter such as SAGA etc.)
  (Original lens mount is replaceable by a customer using precision Philips screw driver to unscrew fixing screws)

(*1) 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.

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

(*3) Any other higher magnification close-up lens, UCL-100M67 or UCL-67 cannot be combined as they significantly degrade image quality.

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

(*5) Focal length of UCL-67 M67/UCL-67 LD standalone and not combined focal length with camera’s master lens.

Compatible lens

• 60mm-100mm range macro lens for full-frame digital SLR (*6)
• 40mm-60mm range macro lens for APS-C (*6)
• 45mm-60mm range macro lens (6), standard zoom lens (1) for mirrorless camera
• Compact digital camera with maximum optical zoom 5x or less (*1).

(*6) Vignetting may be observed using for a housing system which has significantly long distance between camera master lens and port lens surface or this product and port.
