B+W 702 ND 25% Grey Grad MRC 77mm
B+W 702 ND 25% Grey Grad MRC 77mm
The filter is coloured neutral gray with a smooth transition into the neutral filter half. With screwed filter the rotatable mount allows an exact horizontal alignment. The glass substrate of the B+W ND filter 702 is absolutely plane and parallel and finely polished. This guarantees a long lasting high optical quality. By means of thin layer technology the ND gradient is evaporated.The below values refer to the darkest filter glass parts:
702 + 2 stop (25% transmission) ND4
The graduated ND filters are provided with a high quality MRC coating. MRC (Multi Resistant Coating) coated filters have an MC layer ensuring a high transmission and maximum anti-reflective surface. Scattered light is eliminated and by this means achieving more brilliant colours and higher contrasts. Due to the low residual reflection MRC reliably avoids ghost images possibly caused by re-reflection from the sensor surface. In addition, MRC prevents the filter from scratches by means of an increased layer hardness, at the same time maintaining the high optical quality. Furthermore, MRC is dirt and water repellent and makes cleaning much more easier.
