An ideal protective filter for outdoor use, the UV Haze 2A from Tiffen is a clear UV filter that helps to reduce haze and unwanted blue color casts when photographing at high altitudes or near water. The 2A strength of this filter is more effective that the standard Haze-1 filter at reducing haze and is especially well-suited for aerial and drone photography applications. Additionally, as a clear filter, it can also be used as general protection for the front of your lens to guard against scratches, fingerprints, dust, and other elements.
