What Is a Digital Camera?
A digital camera (or digicam for short) is a camera that takes video or
still photographs, or both, digitally by recording images via an
electronic image sensor. A digital camera stores thousands of images
(PJPEG format) on a single small memory device, allows deletion of
images from the memory device, and provides the capability of recording
video with sound. There are two types of digital cameras.
- Point and Shoot (very compact)
- Single-Lens Reflex (SLR)
How Does the Canon SX20IS Point and Shoot (PAS) Differ From an SLR Camera? Images displayed on the viewfinder: PAS: The image displayed will be off sightly in centering and size. SLR: What you see is what you get.
Cost and Size: PAS: Less expensive and smaller. They can fit into a purse. SLR: More expensive and larger.
Zoom: PAS: Limited. SLR: No limitation.
Picture quality: PAS: May be impacted due to compactness. SLR: Superior.
Weight: PAS: Light weight. SLR: Heavier.
Ease of use:
PAS: Easiest to use because zoom lens is part of the camera. SLR: Zoom
lens must be purchased separately and therefore attached or unattached
based on the shot being taken.
Intent of usage: PAS: Generally hobby. SLR: Generally professional.

additional features of the SX20IS camera:

What About Purchasing Canon SX20IS Accessories?
At a minimum, I recommend you purchase the camera case and rechargeable
batteries. When purchasing, you can purchase just the camera. Or, you
can purchase a package which includes the camera plus accessories. Its
cheaper to buy the camera and accessories in a package rather than
individually.
