I can't answer for this particular camera, but if your nose is X inches from the lens and see the same amount of inches from your nose to one edge of the frame, that's 45 degrees to each side which means 90 degree angle of view. That's wide angle. Distortion is proportional to angle. It's not a defect of the camera but a consequence of projecting a 3d image onto a flat (2D) surface. Like projecting a globe to a map on a Mercator projection. For lenses, "Normal" angle is 50 to 65 degree angle of view. Mount the cam on top of your monitor, sit 24 inches away (measure to tip of nose) directly in front of it in the center of the frame. Then hold one end of a tape measure on your nose and stretch it out to the side parallel to your monitor screen. If you see to the 24 inch mark in the frame it's 2 x 45 degrees = 90. If the 19 inch mark is at the edge it's a 2 x 38 degree = 76 degree angle of view. If the ONE FOOT mark is at the edge of the frame the angle of view is 2 x 27 degrees = 54 degree angle of view. THAT is a normal lens. If you sit TWO feet from the camera, a normal lens will show ONE foot to each side of your nose to the edge of frame, which is about 6 inches beyond the shoulders of an average size person. See here, yes. I measured these and used ARCTAN of (opposite divided. by. adjacent.) Or, ARCTAN of (distance from nose to edge of frame divided by distance from nose to camera lens) to figure the angles. The calculator in Windows 10 has Trig. functions.
