Variable Eyepieces Question

Eagle Optics,

I purchased a Zeiss 20-75x85mm spotting scope, but noticed that the eyepiece has two scales on it, one from 15-56 and one from 20-75. Why is the 15-56 scale on the eyepiece if it is suppose to be 20-75?



Thanks for your interest in Eagle Optics.
The eyepiece for the Zeiss scopes fit either of their scope bodies, the 65mm and the 85mm. On the 85mm scopes, the eyepiece is 20-75x. On the 65mm scopes, it is 15-56x.

There are actually a number of eyepieces that are designed this way, from many manufacturers as well.
