When parallel rays of light strike a lens focused at infinity, they converge to a point called the focal point. The focal length of the lens is then defined as the distance from the middle of the lens to its focal point.
The Crop Factor is a term that can be heard quite often in the world of digital photography. What does it mean that a camera has a crop factor of 1.6x and how does it affect your focal length? We try to untangle this issue and describe it as clearly as possible.
The subject of crop factors and focal length multiplier can be a bit confusing and hard to understand at first â€” we will try to explain it as simple as possible but yet informative enough for you to get the entire picture.
