Can anyone comment on the differences? The "old" version is available for roughly $895, while the "new" version is $1200. What's odd to me is that the old version is 8 oz. lighter, has significantly closer focus, better eye-relief, and two-system focus, in addition to a longer zoom range. All of those seem like advantages. And, when I look at the descriptions of the basic optics,they appear identical. I must be missing something, but I can't see why the new version is better. I have not had hands on these scopes, so I am eager to hear from those who have. Thanks!
