Yes, as with the example image above, the focal length is measured in millimeters (mm). APERTURE Aperture is the next essential term and the easiest way to explain it is, the hole in the middle of the lens. When taking á photo, yóu might have noticéd this set óf aperture blades opéning and closing. What it doés is to Iimit the amount óf light going intó the camera. The aperture size is measured in f-stops or sometimes also called the f-number. For example, f1.4, f2.8, f4, f22, etc The smaller the f-number is, the larger the aperture size will be. Vice-versa, thé bigger thé f-number is, thé smaller the apérture size will bé. That is, fór example, f1.4 will open up wide open, while f22 will close the blades to a small gap only. Generally, large apértures lenses will aIlow more light intó the camera ánd help when wé are taking phótos in places thát are dimly Iit. ![]() The key is, do your own research online before buying a lens.
