INON UCL-G165 II SD Underwater Wide Close-up Lens for GoPro

[Description]

■「UCL-G165 SD」 Underwater Wide Close-up Lens■

• An action camera is a deep focus camera which does not require focusing but prevents a subject gets in focus in close range (within 60cm/2ft range in theory for GoPro® camera) thus not usable for underwater macro shooting. Using standard macro lens for a compact digital camera would not help the situation as it would create vignetting and very shallow depth of field preventing comfortable focusing. The UCL-G165 II lens is so-called "wide close-up lens" specifically designed for action cameras based on their optical characteristic. The depth of field (DoF) underwater will be 10cm/3.9in to 35cm/1.1ft when using the lens for GoPro® HERO12 Black supporting closer minimum focus distance underwater to capture wow photos/clips.
• Maximum angle of view of GoPro® HERO12 Black is approx. 156° on land which will narrow down to approx. 94° when the camera is housed in genuine dive housing and submerged due to different refraction index. The INON UCL-G165 II slightly increases angle of view underwater to 110° to capture dynamic scene played by a subject as the lens frames subject larger than UFL-G140 SD which delivers ultra wide 140°
