B+W Basic MRC UV Filter - 52mm Display Easel The measurement from the middleThe classic amongst the B+W protection filters blocks the annoying UV component of daylight. Invisible UV light is more intense in pure sea air and in high mountain regions and can cause blurring and a blueish cast. The colour neutral B+W 010 UV Haze filter is equally suitable for both analog and digital cameras. It ensures more brilliant images and can remain on the lens permanently as front lens protection.
