■UCL-330 Close-up Lens
Compatible Mount
●The UCL-330 is standard close-up lens with 33cm focal length to shorten minimum focus distance allowing you to get closer to a subject enabling high magnification close-up photography.
●Dual use underwater / land and usable with all zoom range. Even at same shooting distance, it is easy to capture a subject at desired size by adjusting zoom setting.
●The lens is constructed of two plano-convex high quality optical glass elements with inner coating to suppress optical aberrations more effectively comparing to a lens using just one double-convex element, and bring out optimal performance of combined master lens.
●The lens body has screw mount on its front end to stack other UCL-330 for even higher magnification macro imaging. Off course the UCL-165M67 can be stacked as well for further close-up shooting. The threaded part has a slit to drain water from gap between two lenses to easily separate combined lens underwater.
●Highly versatile screw type "M67 Mount" compatible.
●The UCL-330 is directly screwed on a housing which has M67 lens ring. For a housing which does not have M67 lens ring, the UCL-330 is attached via dedicated "M67 Mount Base". For "28LD Mount Base" compatible housing, the UCL-330 is attached on "28LD Mount Base" via "M67-LD Mount Converter for UCL-330/165M67".
(*1) Optional "M67-LD Mount Converter for UCL-330/165M67" is necessary.
 Screw type M67 Mount |  Directly screwed in housing port |  Attached via specific "M67 Mount Base" for each camera/housing model. |

[When using a close-up lens]
*Depending on housing, shooting distance, angle of view etc., the lens may block the built-in flash light from illuminating the entire image. In such cases it is recommended to shoot with an external strobe or flashlight.
*A close-up lens provides maximum magnification at zoom telephoto end.
*Generally, a close up lens shortens the camera’s close focusing distance. With the UCL-165LD, you can place your camera closer to a subject, achieving a larger image. On the other hand, depending on zoom or aperture setting, it may be more difficult to obtain complete depth of field on a distant subject.
*Stacking multiple lenses may cause vignetting at zoom wide end. As you stack more lens, focusing distance gets short and depth of field gets shallow as well.
