SD Front Mask for HERO910/11/12

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® HERO10 Black is approx. 151° 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-G140 SD provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work only with action cameras. * Measured angle of view by INON or calculated angle of view underwater based on the measured angle of view. Not confirmed by camera manufacture. The measured angle of view of “HERO3+ Silver Edition” is approx. 142°(air) which is less wide than the “Black Edition”. So angle of view underwater with this lens is less than 140°. The “HERO3+ White Edition” has not been tested. Dynamic CFWA Imaging Shooting through the INON UFL-G140 SD 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® HERO10 Black on land is approx. 60cm/2ft to 8. With the INON UFL-G140 SD, DoF underwater will be extended to 4cm/1.6in to 8 closer to camera side. * DoF on land is based on focal length/aperture of camera lens and pixel pitch of the image sensor. DoF underwater is measured from "the forefront of the lens".

The INON "UCL-G165 SD" underwater wide close-up lens enables you to shoot a subject from close range of the lens to capture the subject larger in a frame. Get Closer Minimum Focus Distance 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 SD 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 5cm/2.0in to 35cm/1.1ft when using the lens for GoPro® HERO10 Black supporting closer minimum focus distance underwater to capture wow photos/clips. * The depth of field (DoF) on land is theoretical value based on focal length/aperture of camera lens and pixel pitch of the image sensor. DoF underwater is measured from "the forefront of the lens". Ideal Angle of View for Macro Shooting Maximum angle of view of GoPro® HERO10 Black Black is approx. 151° 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 SD 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°. Measured angle of view by INON on land or calculated angle of view underwater based on the measured angle of view on land. Not confirmed by camera manufacture. The measured angle of view of "HERO3+ Silver Edition" is approx. 142°(air) which is less wide than the "Black Edition". So angle of view underwater with this lens is less than 110°. The "HERO3+ White Edition" has not been tested. Professional-level Image Quality Optics is constructed of 2 elements in 2 groups. All elements are made from high refractive index glass lens to minimize whole size dramatically without sacrificing performance. Both lens elements have anti-reflection coating on all surfaces to elicit combined master lens performance with less ghost/flare.  *Note that a lens adapter other than INON SD Front Mask may degrade image quality significantly as such adapter is not optimized for use with INON lens. Using such an adapter is not recommended and may void product warranty. Speedy Lens Exchange by SD Mount  Bayonet INON SD Mount compatible to support friendly and speedy lens exchange underwater. Compatible with AD Lens Holder to hold a lens when not in use.

Lightweight Reinforced Plastic Body Made of reinforced plastic (FRP) for durability and not to compromise benefit of lightweight GoPro® camera. Easy to install to snap on the front of a housing and fix with a thumbscrew. Optional Accessories for Selfie, Follow Camera Using an optional “Ball Adapter for GoPro” attached on the “Carbon Telescopic Arm” to combine with your GoPro camera, is an ideal selfie system to record while swimming around. INON's original fixing screw can securely hold the camera in place, enabling stable video recording underwater without worrying about unexpected camera displacement due to current. All components are designed for underwater use offering superior durability and corrosion resistant characteristic. Attaching a conversion lens on an action camera gets heavy especially when using a “Carbon Telescopic Arm”. Optional“Mega Float Tube” attached on top end of the arm supports comfortable handing underwater without having heavy load on hand grip. Versatility  The bottom of the M67Front Mask for HERO8 has a screw hole to attach joint adapters including "Direct Base III", "Z Joint", "Z Adapter MV" and "Shoe Base M6" to use GoPro® cameras for various applications. The M67 Front Mask for HERO8 comes with "Male Adapter (GoPro) " which is attached on the bottom of the SD Front Mask for HERO8 to use GoPro® compatible accessories. Stability Supplied Mount Adapter enables to install one "D5 Holder" on the left hand side supporting stable shooting underwater. Combining with the “Grip Base D5”* and “D5 Holder” allows you to hold the camera steadily with both hands for stable shooting underwater with less camera shake and you can enjoy a full-scale underwater video system with dual lighting. * Optional “Direct Base YS RT”and ”Z Joint”are required to attach “Grip Base D5”. Tripod, Monopod The Mount Adapter is equipped with the tripod screw (1/4”) to link to a tripod or monopod for shooting no camera shake footage, time-lapse, fixed-point observation etc.
