What is the meaning of the camera lens 18-55
Is the meaning of the focal length, 18-55 represents the shortest focal length of 18mm, the longest focal length of 55mm
That focal length, 18-55 that is the shortest focal length 18mm, the longest focal length 55mm. But because it is APS frame lens, in the APS body on the actual focal length to 1.5
18-55 represents the focal length range of the lens, 18 is the minimum focal length, also represents the maximum viewing angle, 55 is the maximum focal length, representing the minimum Viewing angle. EF-S stands for lenses that can only be used for APS-C format cameras. IS on behalf of anti-shake, STM on behalf of the lens built-in stepper motor, is conducive to fast focus.
The shorter the focal length, see the more wide, the longer the focal length, see farther.
