Inon UCL-G100 SD Underwater Close-up Lens

Inon UCL-G100 SD Underwater Close-up Lens for Action Cameras

INON's popular “SD Mount Lens” is well known by both both amateur and professional action camera shooters 

The unprecedented high-magnification close-up lens with packaged useful Focus Stick enables you to easily enjoy blur-free macro photography.

Bayonet INON SD Mount compatible to support friendly and speedy lens exchange underwater. Optional INON SD Lens Holder can hold the UCL-G100 SD when the lens is not in use.

High Magnification Close-up Lens
The UCL-G100 SD offers the second highest magnification among the UCL-G series close-up lenses. The lens provides 2x magnification (scale ratio) compared to the UCL-G165II SD . The lens is specially designed for shooting tiny critters, enabling ultra-macro photography with GoPro cameras.

*Depth of field gets shallower with higher magnification due to the nature of close-up lenses.

Drastically shorten minimum focusing distance with nearly the same underwater view angle of the camera standalone for friendly use.

Easy-to-use All Around Close-up Lens
A close-up lens with a middle magnification among three UCL-G series lenses, providing twice the magnification of the UCL-G165II (scale ratio) to use for macro imaging. This lens significantly shortens the minimum focusing distance while maintaining the same underwater angle of view as the GoPro® alone and easy-to-use all-around close-up lens with deep depth of field among lenses in the same class.

*Depth of field gets shallower with higher magnification due to the nature of close-up lenses.

Change FOV Setting for Further Magnification
 
The distance between two sticks represents a shooting range of the UCL-G100 when GoPro® is set to "WIDE". GoPro® has several field of view settings, and with "Linear" or other narrower angle of view, it is possible to shoot at an even higher magnification. Shooting at a high resolution such as 4K with "1.4x" zoom can enlarge the subject even more with relatively less image quality degradation.

Blur-free Focus Stick (PAT.P)
The distance between two sticks represents a shooting range of the UCL-G100 when GoPro® is set to "WIDE". Focus Stick tip represents minimum focusing distance and far end of the depth of field is 8.2cm/3.2in from the tip.
It is easy to take sharp and crispy high magnification close-up video by referring to the Focus Stick and checking the composition on the rear monitor.
The Focus Stick rotates 360° and has clicks every 90°, so it can be instantly flipped up when not in use. Vertical installation is also possible. The Focus Stick body is attached to the lens with retaining screw ring and can be separated from the lens when not necessary.

[When using the UCL-G100]
The UCL-G100 is designed only for underwater use. Using on land creates vignetting.
[When using for GoPro]
Set the camera's field of view (FOV)/Digital Lenses to [Wide] for quality-oriented, or [Linear] for magnification-oriented photography.
When using with HERO11 Black, HERO12 Black and HERO13 Black, shoot in 4:3 or 16:9 aspect ratio as vignetting will occur in 8:7 or [HyperView™] mode which compresses footage in 16:9 aspect ratio by using the full 8:7 sensor.
[SuperView™] mode is not recommended. The SuperView™ mode stretches both ends of the image inside the camera to fit into a 16:9 aspect ratio from originally obtained 4:3 aspect ratio image by the camera sensor. Since the edges of the frame are stretched horizontally, using an attachment lens further stretches the edges of the frame, resulting in an unnatural image.
Set the camera's image stabilization (HyperSmooth) to [Standard], [High], or [On]. Setting to [Off] will cause vignetting in image corners, and [Boost] will crop the image significantly.
The FOV/Digital Lenses setting [Wide] in Photo mode causes vignetting in image corners.
