The Inon UCL-165LD is high magnification close-up lens with 16.5cm 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. Even at same shooting distance- it is easy to capture a subject at desired size by adjusting zoom setting (*1).
The lens construction is 2 elements in 2 groups with high quality optical glass with inner coating to suppress optical aberrations more effectively and bring out optimal performance of combined master lens comparing to a lens using just one double-convex element.
The lens barrel has joint screw mount on its front side to hold another INON M67 series close-up lens for super macro imaging (*2).
Lockable bayonet mount INON 28LD Mount compatible. Easy- speedy yet reliable installation on 28LD Mount Base can be obtained.
The UCL-165LD is attached on compatible camera / housing via 28LD Mount Base which is exclusively designed for each housing.
(*1) Sole use for underwater. Compatible with zoom range of middle to telephoto side. Using on land and zoom wide side setting underwater will have vignetting.
(*2) Stackable attachment lens is INON M67 Mount series close-up lens UCL-330 or UCL-165M67. This product (UCL-165LD) cannot be stacked together. [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. Product Specification
