TThe UCL-330 is close-up lens providing 330mm focal length (+3 diopter) where shooting distance is 330mm from lens surface when camera’s focus position is set to infinity, which is half power of the UCL-165M67. Especially useful for super zoom digital camera when shooting a shy subject with best suited distance and magnification.
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"or "M67 Lens Adapter 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".

Usage Notice
- 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 this product, 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.
