NiSi Pro Nano 1.5-5 Stop Enhance ND-VARIO 40.5mm

NiSi Pro Nano 1.5-5 Stop Enhance ND-VARIO 40.5mm

Continuously adjustable grey filter with very high quality optical glass, for an excellent price. Polarpron McKinnon a competitor has been found for the series! Another advantage of NiS is that the product is available in all the main sizes, unlike McKinnons.

Filters are coated NiS with high quality NANO coating, which repels dirt and moisture and provides a highly neutral colour fastness. The frames are made as small as possible to avoid distortion. However, slight distortion may occur at extreme wide angles, although this applies to all filters.

Use of a continuously variable grey filter

This filter basically replaces several filters with one. You can adjust the amount of transmitted light by rotating the filter with a rotary polarizer. The adjustable grey filter consists of two CPL filters on top of each other.

The most common uses of such filters are video recording. In video, you often need to set the shutter speed to 1/50, for example, and if you don't want to dim the aperture all the way down, you often need a gray filter in front. An adjustable ND makes it easy to adjust the desired amount of light quickly and conveniently. NiSi Pro Nano 1.5-5 Stop Enhance ND-VARIO filters are deliberately moderately adjustable. There are plenty of ND3-1000 filters on the market, these filters are pretty much unusable anywhere near either extreme. Similarly, the colour gamut is often heavily skewed and a fair amount of post-processing is required. NiSi has aimed for as neutral a colour scheme as possible in its filters, which is a very desirable feature, especially in video.
