I currently have a 65mm HD Swarovski ATM. After this years hunt, I decided that I had rather lug around the extra weight, and go with a larger scope. I was going to go ahead and just get the ATM 80 HD, but I just discover that I can get a pretty good deal on a Zeiss Diascope 85mm, about $750 less than the ATM 80 HD. Weight is one big negative that I can think of between the two. For you guys that have used both, what are your thoughts when comparing these two scopes?
