Question about Canon EF 180mm f3.5L Macro USM AutoFocus Te..

Reviews often speak of this lens as an excellent telephoto lens.
I guess I'm rather ignorant about the lens specs:
* Lens Type: teleconverter
* mounting_type: Canon EF
* Camera Magnify Power: 1 / 1
* lens_system_special_functions: Macro
* maximum_aperture_range: F/3.5
* Minimum focal length: 180 millimeters
* min_focal_range: 18.9 inches
* Focus Type: auto-focus, manual-focus
* Real Angle Of View: 13.5
* Weight: 2.4 pounds
* Item Display Diameter: 3.3 inches
* Length: 7 inches

Zoom is often referred to as 6X, 10X etc. Can anyone tell me what X would
this be equivalent to?

With cameras, the "X" is a ratio of the shortest to the longest zoom;
it's not a power of magnification like with binoculars and telescopes.

A 70-210mm zoom lens would be 3X (210/70). A 28-300 would be 10X
(approximately - 300/28 = 10.714285714285714285714285714286 to be
precise). The actual magnification will depend on the size of the
sensor (or film frame, if applicable).

As others have noted, since this is not a zoom lens, but a fixed focal
length, the actual zoom would be "1X".
