Could have been something wrong with the Zeiss.
I had several people compare the 2 and all preferred the Leupold between the 2 scopes I had. It was for my sons rifle and he said he liked the vx2 better.
I have both Zeiss and two of the vx2's with heavy duplex and most people like the vx2 better. I think the heavy duplex makes it look brighter in low light.
