Hey friends I recently bought binoculars without anyone suggestion or knowledge. I am in market I found them good so I bought it. I need to know that is it compulsory to know about rating before buying binoculars and what does binoculars ratings mean. One I bought have 8 x 21 and field 7 but i have no idea what that means? Anyone have good knowledge of binoculars ratings please explain it to me in detail? I will be thankful to you.
