Well, you don't need internet opinions to figure this out.
If you look at the weights on scopes??.
Zeiss 65mm 39 oz. 85mm 52 oz.
Leica 65mm 40 oz. 82mm 48 oz.
Kowa 77mm 46 oz.
Swarovski 65mm 55oz 85mm 67oz
For the guys who want to throw in vortex, they are as heavy as the swarovski.
You want light weight and quality. with no budget limitations, throw out the vortex and swarovski.
My personal opinion would be that the best choice all around would be the Leica Televid 82mm APO. Second choice would be the Kowa Prominar TSN 773.
If you wanted to save a bit more space and weight, I would switch the Kowa into first place.
If you wanted to save weight and go with a cheaper scope?
Nikon prostaff 5 82mm 33oz. 60mm 26 oz.
Yes, its not going to have the same quality as the Leica or the Kowa. But they are less expensive and very light.
The question becomes, can you get by with the lower quality level?
Meopta meostar makes a fairly light weight scope, that is mid budget, that delivers a higher quality level than optics like the vortex razor.
The 82mm scope is 50 oz without the eyepiece.
Puts it in a weight class similar to the swaro and the vortex, but the price is cheaper than the swaro, and the quality is higher than the vortex.
If you want to save weight and space in the pack, going to the 65mm scopes might be for you.
The Ziess and the Leica would be my choice in the smaller sizes.
When I need to save space and don't want to pack the weight, I leave my high dollar scope at home and take a very inexpensive scope.
It weighs only 5.9 oz at 65mm and does very well.
The quality at high magnification is not as good as my other scope, but when you are trying to save space and weight, you have to make some sacrifices.
