The PRO version of this amazing lens features a GLASS front dome - the glass version is durable and produces better image quality

INON UFL-GR140 PRO ZD Underwater Semi-fisheye Conversion Lens Supports Large Image Sensor, Large Aperture Semi-fisheye Lens. The rear lens group has been enlarged while maintaining the same size and weight as the previous model. Works well with action cameras with large sensors, such as the Insta360®Ace Pro, to film at the maximum field of view without vignetting. Shooting at 8:7 aspect ratio of GoPro®HERO11 and later models are also supported without vignetting.

Which lens - Which mount - Which housing ?

Please check our Action Camera Lens Mounts Chart to determine which mount you can use on which housing for what lens.

INON's popular “SD Mount Lens” among both amateur and professional action camera shooters expands its lineup with the new “ZD Mount Lens”. The ZD Mount Lens offers broad compatibility to shoot in full frame 8:7 aspect ratio of GoPro as well as to use with an action camera with larger and quality image sensors. 

Supports Large Image Sensor, Large Aperture Semi-fisheye Lens

The rear lens group has been enlarged while maintaining the same size and weight as the previous model.

Ultra Wide Even Underwater

Though an action camera is equipped with ultra wide lens, its coverage underwater will dramatically narrow down due to different refraction ratio between air and water.

For example, maximum angle of view of GoPro® HERO13 Black is approx. 156° on land which will narrow down to approx. 94° when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UFL-GR140/UFL-G140 provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work only with action cameras.
 
Dynamic CFWA Imaging

Shooting through the INON UFL-GR140/UFL-G140 lens enables you to shoot a subject at close range to benefit deformed and/or perspective result.

The native depth of field (DoF) of the GoPro®HERO13 Black on land is approx. 60cm/2ft to ∞. With the INON UFL-GR140/UFL-G140, DoF underwater will be extended ∞ 4cm/1.6in to ∞ closer to camera side.

Professional-level Image Quality

Both UFL-GR140/UFL-G140 lenses are optimized to produce quality images from the minimum focusing distance to infinity. A 5-layer multi-coating on the inner surface of the acrylic dome ensures excellent image quality comparable to that of a glass dome, while keeping budget price.
