This capsule give you insight on how an SLR camera takes photos

These cameras have a unique viewing system which uses a mirror to reflect light from the lens through a separate optical viewfinder.

What you see in the viewfinder is the picture that will be taken.

In order to capture an image the mirror is flipped out of the way, allowing light to fall on the imager.

Since no light reaches the imager during framing, autofocus is accomplished using specialized sensors in the mirror box itself.

These type of cameras are purchased by professionals.

This module is about point and shoot cameras and the canon powershot sx20is is that type of camera all cameras with this point and shoot feature can not have extra lenses added to them.
There are camera`s that have extra lens that can be fitted so if you see the frase point and shoot they cant have lenses added.
