Multi-layer Coating Neutral Density Filter

Why Neutral Density filter is important?

We have already entered the era of super high sensitivity, super high resolution photographic equipment. Obviously, the power of this huge sensor can easily be affected by lenses and other optical accessories that are located right on the path of the light entering the camera. In other words, the filter quality serves as the front "gate" for the light to enter and is of the utmost importance.

In particular, ND filters have become a must for high sensitivity cameras with ISO settings that starts from 200 or 100. This is the reason that ND filters currently garner a high level of attention and have strict quality requirements. Professional photographers requires ND filters that decrease light volume in the most natural and harmless way.
