The Swarovski 25-50xW Eyepiece displays a much wider angle at 25x than the 20-60xS eyepiece does at 20x, giving a field of view ranging from 126 feet (25x) to 81 feet (50x) at 1000 yards. It also has a larger image circle. All of this means that it will reduce the likelihood of vignetting while digiscoping. Eye relief is a generous 17mm.
Swarovski guarantees for the entire range of branded products purchased from authorized Swarovski retailers, a global and full life-time warranty
covering manufacturing and material defects under normal use beginning with the date of purchase.
The warranty does not cover damage caused by accident or maltreatment. All warranted defects will either be repaired pending feasibility and availability of replacement parts or replaced with either the same product or with a piece of equal value as determined by Swarovski. Swarovski however is lenient with these services.
