[QUOTE="Litehiker, post: 1775866, member: 54178"] So much of the differences between scope glass of [I]equivalent[/I] price levels is due to: -> the choice of coatings (assuming [U]fully [/U]multi-coated lenses) -> the compromises made to get features like a shorter scope, a bigger objective, etc. [B]EX[/B]. my Bushnell LRTS 4.5 - 18 x 44 scope ia 14" long - kinda longish for a hunting scope. But... that length means fewer lenses in the objective area (ahead of the erector tube lens group) because shorter scopes, all else being equal, require more bending of light thus more lenses, thus more chance for loss of optical clarity. Also larger objective lenses themselves require more bending of light and, again, more lenses IF designed correctly. Eric B. [/QUOTE]
