The most important part of our eyes is a convex lens inside it that is made of living cells. The human eye is like a camera having a lens on one side and a sensitive screen called the retina on the other.
What is focal distance vs focal length?
Focal length in photography comes up far more often than focal distance, which is an entirely different property of a lens. Focal distance is related to focal length but is not dependent on it. What is this? Focal distance is the distance between the subject you are focusing to the camera sensor.
What focal length is best for video?
35mm is the go-to focal length for most interviews, standardized by both “commercial” promos and documentaries.
