This SG2.1x42 binocular uses an optical design of a Galilean type telescope system. With the characteristics of this system, real field of view, apparent field of view and eye relief are not determined strictly.

Although only the eye relief is described in the specifications of this product mainly, it is indicated as reference for the person who wears glasses.

<Reference specifications>
Actual field of view : 12.2 degrees
Apparent field of view : 25.2 degrees
Eye relief : 8.4mm*

* The values of the actual field of view and apparent field of view are measured based on an 8.4mm eye relief. If the distance of the eye relief decreases to 5.6mm, the apparent field of view will increase to 28 degrees (the actual field of view will be 13.6 degrees.) Therefore, these vary with your viewing position.
