Different Sizes of Lenses

NOAIDA provides three types of aspheric lenses: 50mm, 66 mm, and 69 mm. But what do these numbers mean, exactly? They measure how large the lens is at the rim. This 69mm opening is larger than the one on a more staid phone, and simply allows in more light. It's particularly useful when you're in dark environments, such as indoors or at night. But, a smaller lens, like the 50mm, is a lot easier to live with in case you’re on the go. It’s small enough to stow well in your bag, or even your pocket. The size you select will depend on the lens itself with regards to what you plan to use it for. Decide if you want to photograph inside or outside and that will help decide.

How Aspheric Lenses Equalize Images

Let`s check out one of the most interesting parts about aspheric lenses, how they enhance the quality of your photos. These lenses have a unique shape that prevents blurry spots and makes colors appear brighter and more vibrant. This means your photo will appear clearer and more detailed when you click it. These lenses can be used for different types of photography. Take close-ups of flowers, portrait photos of your friends, or beautiful scenery while you are out in nature. The sky is the limit!
