[QUOTE="Chrismadrid, post: 139638, member: 4416"] NEED? it will depend what magnification you shoot at. They HELP at any magnification for precision work as they will eliminate errors due to parallax - they really come into their own at HIGH magnifications where the depth of field (not width of field, aka FOV) reduces considerably (i.e. you'll loose focus) and ESPECIALLY close in! Most decent top end scopes have some form of adjustment where logic demands it. If you were going to shot (as an example) ONLY at 600yds however, yes I'd consider a fixed lens and have it reset to be Parallax free at that distance. [/QUOTE]
