B+W 34mm Digital Pro Ultraviolet (UVa) 010 Multi-Resistant Coated (MRC) Filter

The B&W 34mm Digital Pro Ultraviolet (UVa) 010 Multi-Resistant Coated (MRC) Filter isa wise initial investment. B+W UV filters are excellent general purpose filters since they will not only protect your front element from airborne contaminants as well as fingerprints but also help you get better images at high altitude and while on the water. Using this filter will diminish the bluish cast caused by the various atmospheric factors, yet, it will not have an effect on the color balance of your shot. No increase in exposure is required.

A UV filter is the best available protection for the front element of your lens. A lens that accidentally gets dropped on its front element while hiking can potentially be saved by purchasing this item. Some people refer to them as "cheap insurance".
