Inon Gran Angular UFL-G140 ZD para GoPro

Ultra Wide Coverage, Even Underwater

Standard action cameras lose their ultra-wide angle underwater due to the difference in refraction between air and water. For example, the GoPro® HERO13 Black offers a 156° angle of view on land, which reduces to 94° underwater when placed in a standard dive housing.

The INON UFL-G140 ZD restores and enhances this functionality, delivering an impressive 140° semi-fisheye view underwater—perfect for capturing expansive underwater scenes with just your action camera.

Measured angle of view by INON. Calculations are based on the HERO3+ Black Edition. Other models may yield different results.

Close Focus Wide Angle (CFWA) Imaging

Unlock dynamic underwater shots with the INON UFL-G140 ZD lens. It allows you to capture subjects at close range, creating dramatic deformations and perspective effects. The GoPro® HERO13 Black’s native depth of field (DoF) on land is approximately 60cm/2ft to infinity. With the UFL-G140 SD, the underwater DoF extends to an impressive 4cm/1.6in to infinity—ideal for stunning close-ups.

DoF figures are based on camera specifications and INON testing.

Professional-Grade Optics

The INON UFL-G140 ZD lens features a robust 4-element/4-group design with a high-refractive-index rear glass element to minimize size while maintaining performance. The front acrylic dome includes five-layer multi-coating for premium image quality comparable to optical glass domes—all at a budget-friendly price.

Use only with INON ZD Front Mask adapters. Non-INON adapters may degrade image quality and void the product warranty.
