The type of binoculars you will use depends a lot on how you are going to be using them. If you want to get a pair of binoculars for yourself then you might benefit from knowing what you want to use it for before you buy a pair. For example if you are looking for binoculars that are going to be used to observe wildlife then you will want something that has an 8 x 30 lens as they are the best type of lenses for things such as bird watching or hunting animals. You will also want to make sure that you have at least around 350 feet of vision from the binoculars.
The magnification and zoom ability does not need to be all that high for a better the experience as too much magnification can make it difficult to look at moving objects. You might also want to get a pair that is water proof just in case you find yourself around water when in the wild.
On the other hand you might want to get yourself a pair of binoculars that will be used for star gazing. In this case you might want to get a pair that has lenses that are 10 x 40. These lenses will be good for minimal lighting and lets you see stars easily. You will also need to make sure you have good magnification over here. There is no real movement in the stars so a higher magnification will work well here. The larger lens will help you see in the dark. Pat from That Binocular Guy will suggest that you will also want to get yourself a pair that will give you an image stabilization option. This will help you stabilize the movement from your own end and make your vision a lot steadier.
