Question about Cameras
The range of an optical zoom lens refers to how wide angle to telephoto the lens covers. An example of a 6x optical zoom would be an 18mm-108mm lens, which covers wide angle to telephoto. An example of a 3x zoom lens would be an 18mm-54mm lens, which would provide a capability of capturing images from wide angle to normal views. To calculate the x factor of an optical zoom you would divide the largest number by the smallest number on your zoom. I hope this helps!
