Inon UCL-90 XD Mount Underwater Close-up Macro Lens

The UCL-90 series is designed to use solely underwater to acquire a high-quality image from its compact body thanks to HR glass providing a long working distance and wide supports from a macro lens for a full-frame SLR system to a compact digital camera.

High Power +11 Close-up Lens

The maximum magnification when using this lens with a 100mm range macro lens for a full-frame SLR system is x2.23 (area ratio x4.98) which delivers middle power in between UCL-67 XD (+15 diopter) and UCL-165 XD (+6 diopter). High power close-up lens with an underwater focal length of 90mm which is equivalent to +11 diopter.

Long Working Distance for Comfortability

While the UCL-90 delivers high magnification, it still offers long working distance. When using with 100mm range macro lens for an SLR system, working distance (from the front edge of the lens surface) is 69mm at minimum focusing distance.

High Quality All Focus Range

Optically designed sole use underwater to effectively suppress aberrations in all focus range to deliver high contrast and sharp images despite shooting distance.

HR Glass for Compact Body

Using HR glass makes lens size compact supporting a wide range of camera system from the 100mm range macro lens for SLR to compact digital camera. Also, compact lens body has less limitation of lighting enabling you to use a wide variety of lighting techniques.

Achromat Lens

The lenses consist of 3 elements in 2 groups and effectively suppresses chromatic aberration by using achromat lens inside. Also, anti-reflection coating on all lens surfaces suppresses flare/ghost.
