i have bought several pair over the last few years. my eyes were getting bad and i could not focus them thru some binocs.some binocs will be great to look thru for short periods of time. it is those that allow your eyes to stay comfortable over extended use that are the quality ones. just as many have said you get what youe budget will allow. i bought leica 12x50 and they are heavy. i now use the bino buddy straps and i never feel them. very good glass but also very expensive.
