I looked at the zeiss v6, v4, and V8 scopes today. holy crap very very impressed with the v4, the view through the scope is almost like your not looking through a scope the edge is just so thin around the view. I have never seen a scope quite like it. I was told the scope is japan assembled with german parts and jap glass in the japanese factory.
the v6 is mostly the same internals but with schott glass. also assembled in japan. for what its worth I didn't really like the v6, it has much more of a tunneled view than the v4 does. the only thing I wish they did was offer a 3-12 model with the turrets, instead of making you NOT get a turret and having to go with 56mm objective. I would probably buy one. the 4-16 is very easy to get behind and has a CDS style zero stop and covered windage turret.
the thing about these is I don't know if they are better than other offerings in regards to how they do mechanically, the V4 is very very easy to get behind, it takes alot to impress me and this scope die. The good thing though is its zeiss. so you shouldn't take a beating at resale like you do with sale vortex, or the other various phillipino assembled optics.
