I have found myself up a creek and I am looking for a paddle. My wife shot my rifle that sports a VX-5HD and she fell in love, told me she needs that scope. She also really likes her Zeiss binoculars and I can get a pretty good deal on a Zeiss Conquest Z4 with MOA reticle (that's what she requested). Can anyone with experience tell me how well the Zeiss holds up and functions in low light conditions? All I can do is look through them at the store.
