RE: 3-9x40 4-12x50 or ?
I wanted a brighter scope but not the bulk and high mounting position of a 50mm lens so I went to the 3x10x42mm swarovski.They are just as bright as a 3.5x10x50 leupold with less bulk and they can be mounted with lower rings.Both of these scopes are costly and not mid priced as icelander requested so I would instead recommend the bushnell 3200 3x9x40 as it is as good a scope as is available for the money.
