Schmidt & Bender Summit is very similar in design to 2.5-10x56 Klassik, but it is smaller and lighter and this way better for stalking and mountain hunting. It offers great long range and at the same time close range capabilities. It is the only scope made in a 1 inch main tube by Schmidt & Bender. Because of the big eye relief, it is a very good to use on a magnum rifle.
The Schmidt & Bender Summit 2.5-10x40 has fixed parallax at 100 meters, it comes with the standard posicon turrets, which have a reticle position indicator build in the turrets that shows if the reticle is in the midle of the main tube, and the reticle is set in the second focal plane (reticle size doesn't change with magnification), for less target coverage.
The Schmidt & Bender Summit rifle scopes can only be mounted with 1 inch rings.
