FocusEd: Crop Factor Explained



In this FocusEd video, we discuss the sometimes confusing aspects and nature of crop factor. This is not about how many bushels of corn an acre of rich soil in Iowa will yield—this is about how your combination of optics and sensor size affects the angle of view of your lens. When you have a camera with a sensor smaller than a full-frame sensor or 35mm film, it effectively changes the focal length of your lens, and therefore, your angle of view. This video explains how to apply the crop factor to figure out the 35mm equivalent of your lenses.
