There are always new models but the inherent designs are still the same. Since the dawn of time, man has looked up at the heavens and wondered the beauty it may contain.
Some are too powerful, and others not powerful enough. The size varies a lot, smaller binoculars are more expensive, but they might be just as powerful as the big ones. The binocular rating has two basic parameters, magnification and aperture.
A telescope allows the universe to come to you, in other words objects of long distance come closer, while a microscope puts small objects to become bigger so you can see. Binoculars for deer hunting might not be the best type that you would use for hunting rabbits. Also when you are looking for a pair of hunting binoculars you might want to look for a pair with a range finder feature.
You can easily calculate it by dividing the aperture by the magnification so that 7 x 50 binocular has an exit pupil of just over 7mm. Binoculars that have built in digital cameras are becoming increasingly popular among photographers, bird-hunters and those spies we mentioned earlier.
