This is the installed price for the 4K LENS 1/2.3 Inch l Resolution 4.35mm Non Distortion Lens 10M F/2.8 70 Degree Yi 4K/4K+.  This lens pushes the image closer to the action and reduces distortion.  The trim ring around the lens may become damaged during installation and the area around the lens can become marred.  As a result, expect some abrasions around the lens area of the camera but it is guaranteed to function correctly.  A custom set of seals are installed to close gaps and protect the inner chassis. The image in this listing shows an example of one after installation.
