What Is LDC and How Does It Affect The Camera's Field of View?

This model features built-in LDC, this feature allows the user to adjust lens distortion correction. Lens distortions typically occur when using wide angle lenses, LDC works to automatically correct these distortions allowing the captured video to match a more real-world setting which helps to deliver an optimal viewing experience. 

By default, LDC will be enabled on your device. This correction will allow the camera to view the area in a 170° horizontal, 75° vertical and 175° diagonal viewing angle, however, disabling this feature will allow the camera to view the area is a full 180° horizontal, 78° vertical, and 180° diagonal viewing angle.
