The subjects passing across this product very fast appear
crooked.
This is called the focal plane phenomenon. This is not a malfunction. Because of the way
the image device (CMOS sensor) reads out image signals, the subjects passing by the lens
rapidly might appear crooked depending on the recording conditions.
