Leica was the first brand to launch the 2x wide-angle zoom eyepiece, when they finally reached the market in December 2008. The magnification goes from 25-50x with a crisp clarity all the way out to the edges of the image. The eyecup is of modern twist-type. Unfortunately the bayonet mount was changed in the latest update, which makes this unit Impossible to use for older Televid-scopes.
