There is a difference between $500 binoculars and $2500 binoculars. The differences are slight. Whether or not you can see and appreciate the differences depends on the individual. It may be seeing a third point on a buck or gaining an extra two or three minutes at dawn and dusk. Some may notice those differences while others may not. It is tough to justify the additional cost of the best, but they cost more for a reason.
