Did you think about the Adjustable objective that lets you move the scopes adjustment to shoot diffrent yardages without re sighting it in or playing the high low gessing game.You are also able to add a sun shade to reduce glair.The VXII and VXIII has a Multicoat lens system.The noncritacal eye relief matches your constant eye relief.I never had a problem with mine.You also get allot more diffrent cross hairs to pick from than a Ziess.
