Reduces blown-out highlights and blocked-up shadows on the screen, allowing for the desired expression. "Half ND4 PRO" is best for standard to telephoto lenses. Using this product with an ultra-wide-angle lens will make the boundary of the ND filter appear clearly. If you want to avoid this, for lenses wider than 35mm, we recommend the "LEE Half ND 0.6 <Soft Type>" or "cokin Medium Gray 2 Filter (Z121M)" (both 100mm wide), which have a gentler gradation at the boundary. The boundary is not noticeable with standard or telephoto lenses.
