Purchased around 2018 and used a few times in the ocean. After that, it was stored indoors, but I am selling it because I have no plans to use it. In my amateur opinion, the lens surface and surroundings are in good condition with no scratches. https://www.inon.co.jp/customer/discontinued/action/uclg165sd.html I am also selling other lenses, so I accept combined requests. ● Significant reduction in minimum shooting distance Action cameras are pan-focus cameras that do not require focusing. However, it was not possible to focus within a few tens of centimeters in front of the lens (for example, theoretically within about 60cm on land for GoPro®), and it was not possible to take close-up shots by approaching the subject. Even if a general close-up lens for compact digital cameras is used with an action camera, vignetting occurs in the four corners of the screen, or the depth of field becomes extremely narrow, making it impossible to focus. The UCL-G165 SD lens is a wide-angle close-up lens specially designed to match the unique lens characteristics of action cameras. The depth of field underwater is "5cm to 35cm" for the GoPro® HERO11 Black. The minimum shooting distance is shortened, allowing for powerful shots close to the subject. ● One-touch exchange with SD mount The INON SD mount, which uses a bayonet mount for the mounting part standard, is adopted. Lens attachment and detachment/replacement are possible instantly, even underwater. It supports the "AD Lens Holder" for holding the lens on an arm, etc. ■ Compatible models Olympus STYLUS TG-Tracker Sony FDR-X3000/X3000R Sony HDR-AS300/AS300R GoPro® HERO11 Black GoPro® HERO10 Black GoPro® HERO9 Black GoPro® HERO8 Black GoPro® HERO7 Black GoPro® HERO6 Black GoPro® HERO5 Black GoPro® HERO+ LCD GoPro® HERO+ GoPro® HERO GoPro® HERO4 GoPro® HERO3+ GoPro® HERO3 #Halloween on Mercari
