■UCL-165LD Close-up Lens
●Focal length 165mm (+6 diopter) high magnification close-up lens with 165mm shooting distance from lens surface when camera’s focus position is set to infinity. Using minimum focusing distance will shorten minimum shooting 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.
