Vortex Razor HD 11-33x50 scope provides very clear optics. I selected this brand a model for it's size and optics. The optics in this scope is sharp and crystal-clear through the zoom range. The light weight and small size are great for travel and hiking into remote wildlife areas. The only downside, in my opinion, is the apparent vulnerability of the focusing knobs to accidental impacts, even light ones. Im already trying to design a protective shield to prevent breakage in normal use. In general, Im very pleased.
