Divide your largest focal length(676mm) by the focal length of what is considered a standard focal length(50mm) for most 35mm cameras and you will arrive at 13.52X. This is an arbitrary formula but it's the way I've always computed this question.

The Pentax X-90 is not as long as the Fuji HS-10 at 30X optical zoom. And the HS-10, while more expensive, is a better camera, in my opinion.

It relates to the total range of the zoom, not the range from the "normal" focal length, which would give you the magnification of the telephoto portion only. If the equivalent focal length of the 26X lens is 26 to 626, then 26X is 26 X 26 = 626. Or 626 26 = 26.

The 30X HS 10 is 24 - 720. Then 24 X 30 = 720.
