SUMMARY: Advertised digital camera zoom levels may not just be optical zoom.
 
Be careful when reading a manufacturer's specifications on a digital camera's zoom factor.

Many digital cameras may mention that a camera has a 10x "Combined" or "Total" zoom. This *may* mean that a camera has a 5x optical zoom and a 2x digital zoom (5 X 2 = 10). As mentioned previously in MalekTips, you should only concern yourself with optical zoom as digital zoom just does a pixel interpolation when taking photos, resulting in photographs that may not be as sharp as you'd like. Read the specifications carefully, and if you have any questions, ask a camera salesman about the camera's optical zoom only.
