I understand the Zeiss 4X does test at four inches of eye relief. But has no where near the forgiving nature of Leupold's 4X.
Some have also reported that they have had trouble with the very fast focusing ocular moving when carried close to the body. I've had that trouble with my locked ocular Leupolds. While none of my Leupolds have ever done enough to spoil the image focus when I need it in a hurry, I can see where this could be a problem if I hunted with something that has the super fast euro stlye focusing system.
