INON UCL-67 M67 Close-up Lens (macro lens)

When used with Nikon 105mm (AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED), the lens delivers a 2.7x magnification (area ration is 7.65x)Yet providing ultra-high magnification, the lens offers ample working distance for easy lighting. An optional adapter ring allows to stack UCL-330 or UCL-165M67 in front for even higher magnification…We believe this will be “killer” lens for many of enthusiastic macro lovers!

• 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. 
• 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. 
• 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. 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.
