INON UCL-67 M67 CLOSE UP LENS
The UCL-67 M67 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 a compact system.
- 60mm-100mm range macro lens for full-frame SLR (*1)
- 40mm-60mm range macro lens exclusively designed for APS-C (*1)
- 45mm-60mm range macro lens (*1), standard zoom lens (*2) for Micro Four Thirds
- Compact digital camera with maximum optical zoom 5x or less (*2)
(*1) Vignetting may be observed depends on the distance between the master lens and lens port glass and/or UCL-67 and lens port glass.
(*2) Only usable when the focal length is between 60mm and 100mm range at 35mm film equivalent. Beyond this range, there will be vignetting on the wide side and deteriorated image quality on the telephoto side.
Powerful magnification with focal length 67mm (+15 diopter). The maximum magnification of the UCL-67 with a 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 a long working distance. When using with 100mm range macro lens for SLR, the 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 a macro lens for full-frame digital SLR with a compact body yet delivering high magnification and superior image quality.
Employing an 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 ranges 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 lenses, "UCL-100M67" and "UCL-67 M67" are not usable as those combinations will have significantly degrade image quality.
Lens mount is a highly versatile screw type "M67 Mount".
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 the 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 a precision Philips screwdriver to unscrew fixing screws.
