I appreciate the insight. Thanks!Ive had the 7s, very good glass. There was a guy selling a pair either here or AT for 350ish in the last few weeks. Worth that all day. Id say they might have SLIGHTLY better edge to edge clarity and resolution over the BX-4. The only complaint I had with them is that the armor was kind of tacky and didnt slide in and out of a harness freely. But you have the zulu5s with the same armor, and if its not a problem with them, it wont be with the 7s.
I believe the 5s are made in China and the 7s are made it japan, so youd expect the build quality and glass to be better on the 7s........but that couldve been changed at this point. Its been a few years since I check where each was made, they mightve moved the 5 production somewhere else.
Sent you a PM.I appreciate the insight. Thanks!
