Message: <blockquote data-quote="dries1" data-source="post: 3668505" data-attributes="member: 26646">Dennis,Good thread starter, I was wondering the same thing myself.The porro is a NVF 7X40 Zeiss Jena used in the cold war, it has been used by many paramilitaries over the world. A heavy glass providing over 8 degrees FOV and almost indestructible like the old Hensoldt DFs. The Docter 7X40 roof is an upgrade to the original Zeiss jena EDF 7X40 also used in the cold war but with modified lens coatings to take away the Zeiss Green color tinge (It is essentially the same glass). It is a great bino for hunting or general field use in any weather, a bit heavy for some and not for those who do not like IF glass. The field of view is ~130m/1000m similar to my Zeiss Octarem 8X50s.I wonder if the quality will go down, the Zeiss FL 8X32 I have is constructed of primarily non metal and it is very well thought out glass, but many glasses that are out today are using cheap plastic, and are not put together well as well as those 15 years ago. An example are my Hgs, made in 2002 through 2004, a bit heavy but very well made and have proven the test of time. I still get pleasure using them.I tend to buy binos that have been around for a period of time  (in years not a few months) I just procured a mint EDG 8X32 proven to be a good glass over time and while many purists say the FOV is not large enough ,7.8 degrees is almost 8 so to me the same essentially. The same is with the FL 8X32 a proven bino with no issues and it has been around for a while.I hope that my Zeiss SF 8X42 issue gets resolved, but as a backup I have a 8X42 EDG coming my way, again a proven glass with an actual track record.A.W.</blockquote>
