B+W is a German-based company that produces a range of high-quality filters for photographers. Two of their most popular types of filters are the UV Haze and Clear filters.
UV Haze filters are designed to block ultraviolet light and reduce haze, resulting in sharper and clearer images, especially when photographing at high altitudes or in hazy conditions. They also serve as a form of protection for the front element of the lens, reducing the risk of scratches, dirt, and fingerprints.
Clear filters, on the other hand, do not have any impact on the color or contrast of the image and are primarily used as a protective measure for the front element of the lens. They are especially useful in situations where the lens is likely to be exposed to potential damage, such as in extreme weather conditions or when shooting in a crowded area.
Both UV Haze and Clear filters are available in various sizes and thread sizes to fit different lenses, and are made with high-quality materials to ensure durability and clarity. While some photographers prefer to shoot without filters, many find them to be a useful addition to their gear, especially when shooting in challenging conditions or when they want to protect their expensive lenses.
