Inon UCL-G100 ZD Underwater Close-up Lens

Part #: INO-4570018120961

The Inon UCL-G100 ZD is an underwater close-up lens designed for use with GoPro and other action cameras that utilize fixed wide-angle lenses. Action cameras like the GoPro HERO 12/HERO 13 series typically have a deep focus design, which prevents subjects within close range—generally less than 60 cm—from being captured clearly underwater. This optical limitation restricts their usability for underwater macro photography without additional lenses.

The UCL-G100 ZD is part of Inon’s UCL-G series and provides middle-range magnification among the three lenses in the lineup. It offers approximately twice the magnification (scale ratio) of the UCL-G165 II, making it suitable for closer subjects while still maintaining a deep depth of field compared to higher-magnification close-up lenses. Depth of field naturally becomes shallower with increased magnification, but the UCL-G100 ZD is designed to balance magnification and usability underwater.

One of the distinguishing features of this lens is its ability to drastically shorten the minimum focusing distance of an action camera while preserving the camera’s original underwater angle of view. This characteristic allows for improved subject proximity without introducing framing distortion or requiring complex repositioning.

The lens is compatible with the Inon ZD Bayonet Mount System, which supports quick lens changes underwater without tools. When not in use, the Inon ZD Lens Holder can be used to store the UCL-G100 ZD securely, allowing divers to switch between wide-angle and macro shooting efficiently during a single dive.

As an Inon attachment lens for GoPro, the UCL-G100 ZD is built specifically to work with the GoPro underwater camera setup. It avoids issues common with third-party macro lenses, such as vignetting and edge distortion, by matching the camera’s optical characteristics. This makes it a practical solution for users seeking a reliable Inon lens for GoPro that expands underwater imaging capabilities.

The Inon GoPro configuration with the UCL-G100 ZD provides a versatile close-up solution for shooting macro subjects underwater while maintaining consistent image composition and ease of operation. The lens is part of a broader set of GoPro accessories designed to enhance underwater performance without compromising image quality.
