B+W F-Pro 701 Graduated Gray Filter 50% MRC 55

B+W Graduated Gray Filter 701

The neutral gray half of this graduated filter has a transmittance of 50% (1 f-stop), darkening the subject area by one f-stop without altering the color. This filter is ideal for situations where the sky is too bright compared to the landscape, helping to retain cloud detail and prevent the blue sky from fading due to overexposure.

B+W Graduated Gray Filters are commonly used in landscape photography to avoid overexposing the sky while keeping the ground correctly exposed. The effect of this filter cannot be effectively replicated through electronic image processing, as image information is often lost in overexposed areas.

The filters feature a half neutral gray tint with a smooth transition to the neutral filter half. The rotatable mount allows for precise horizontal alignment when the filter is securely attached. The glass substrate of the B+W Gray Filter 701 is a plane-parallel ground and finely polished filter disk, ensuring long-lasting high optical quality. The gradient is specially vapor-deposited using thin-film technology, with the dark edge area of the filter rated at -701 +1 f-stop (50% transmission).

These gray graduated filters are equipped with a high-quality MRC coating. MRC (Multi Resistant Coating) filters feature an MC layer that ensures high transmission and maximum anti-reflection. This coating eliminates disturbing stray light, resulting in more brilliant colors and higher contrasts. The low residual reflection of MRC effectively prevents ghost images caused by back reflection from the sensor surface. Additionally, MRC enhances the filter's scratch resistance due to its increased layer hardness and preserves high optical quality. MRC also repels dirt and water, making cleaning easier.
