The best choice of binoculars depends mostly on how they are going to be used. I find two modes of use, and there are different choices depending on the mode.
One mode is what might be called the ‘quick glance’. You’ve seen movement and want to check it out. Time spent looking through the lenses is a minute or two, often less. For this mode, any of the binoculars mentioned will do a good job.
Second mode is prolonged viewing. At least 10 minutes, often more. I favor the top of the line models like Swarovski because, for me, they produce less eye fatigue. You can’t ‘see’ or feel this difference with the kind of quick look used at a sales counter. You either have to use them for an extended period or take people’s word there is a difference.
The ‘tie breaker’ data point some use in selecting between binoculars is weight. Heavy glass is often left at home where, regardless of price it does no good. My overall first glass of choice is the Swarovski CL 6x30. It’s light weight magnesium body allows me to carry it and not know it’s there. The 5mm exit pupil provides good viewing even in low light situations. Some might say the 6 power is too low, but I find the clarity, lack of eye fatigue, and viewing angle to be a good match whether I’m scouting on the move or taking an extended view of things on a mountain top.
