The sides of the pictures and videos are distorted
Since the lens of the Action Cam is designed to shoot in very wide angles, it is normal for the sides of the pictures and videos to appear distorted. To reduce the fish eye effect, the camera can be set to shoot at 120 degree angle.
NOTE: Depending on the camera model, the angle can be changed by turning on the SteadyShot feature, setting the Field Angle or Angle Setting.
