SLR Magic 62mm MK II Variable Neutral Density (ND) Filter - 0.4 to 1.8 (2.3 to 6 Stops)

الوصف

Unique Design... SLR Magic's uniquely designed variable neutral density filter provides the equivalent brightness range from 2 1/3 (ND 1.3) to 6 (ND 64) f-stop reduction with full practical range. Color shift and cross-like vignette effect commonly found on variable ND filters are avoided through use of special glass and treatment. The versatility of the SLR Magic variable ND filter replaces the need for a set of ND filters and also prevents vignette that may occur when multiple ND filters are used. Digital multi-coating is used to reduce lens flares and ghosting effect caused by reflections. Calibrated markings on filter allow for repeatable positions. Lever on ND filter helps to avoid obstruction during recording when ultra wide angle lenses. The SLR Magic Variable ND has markings from Minimum to Maximum in 12 calibrated positions, which are repeatable. Sharpness of Variable ND filters usually decreases dramatically whenused beyond ND density of 1.0 but the SLR Magic Variable ND filter is able to maintain sharpness throughout the entire density range. Many Variable ND filtersusually show striation patterns in the out-of-focus circles of confusion in the bokeh but the SLR Magic Variable ND filter is optimized to suppress such effects.
