For those who are new to the kit lens Canon EFS 18-55mm/f3.5-5.6, this information may be helpful to understand the lens.
EFS? EF-S
Code in Canon kit lens means the lens is made for a camera that has a
mirror box 2/3 smaller than usual 35mm/EOS camera mirror. The term is commonly known as the 1.6x cropping factor. The lens EF-S was deliberately made by Canon to meet user market middle-class cameras. It's point is located at the camera. The cameras that support the lens EF-S also known as sub-frame camera. The cameras can also use the code EF lenses, or lenses that support the full frame cameras. But cameras can not use the full frame lenses with EF-S code.
Figures 18-55mm lens focal length is addressed. That is the Canon kit lens, we freely choose the focal length from 18mm to 55mm. This is also a zoom lens.
Focal length is the length between the focal point of the lens with the camera sensor point. Well this lens focal length determines the width, breadth of view coverage that can be received by the camera. For example, focal length lens with 18mm wide-lens view of the extensive coverage of more than 35mm focal length lens.
The figure shows the description of f3.5-5.6 lens diaphragm. Description
This figure shows that if we change the focal length lens, for example,
from 18mm to 35mm, large aperture lenses will also change
automatically. Remember that the larger the diaphragm, the smaller the lens opening to receive the light that goes into it. The figure also shows the number f3.5 aperture lens is the largest owned.
