I've come at this two different ways, Daniel.

We think of a "normal" or 1X lens as in the 50-55mm range. That would mean a lens in the range of 100mm would be 2X, 200mm a 4X etc.

I have also observed that an 8X pair of binoculars I used to own was very similar in magnification to a 400mm lens I also used to own.

Gregg

How many mm of lens is the equivalent of 1x power binoculars and so on?
