Image shift of the reticle has been a problem that has plagued variable power rifle scopes for over 50 years. In other words with say a 4 to 12 x 50 variable scope the crosshairs have a different point of aim at 4x to what they do at 12x. The high end variables from Japan, Germany and the USA have pretty much got this sorted in more recent years, to the point where it isn't an issue at all. These riflescopes aren't cheap. I wouldn't trust a cheap variable even today.
