3.8

1 source$93.99as of Oct 11

At around $90 for a wide 1-9 stop variable ND, the K&F Concept Nano-X Variable ND ND2-400 is the value pick.

Photography Life and Digital Photography School both found the color cast minor and easily corrected.

— Putter-style adjustment handle with stops marked on the frame
— 28-layer nanocoating that is water- and oil-repellent

— Class-leading image quality with no major color shift
— Beautifully built and easy to learn on

Watch-outs

— Expensive at around $250

How they stack up

K&F Concept Nano-X Variable ND ND2-400

The K&F Concept Nano-X matches the Hoya Variable Density II's wide 1-9 stop range at a much lower price, but lacks the hard stops of the NiSi True Color ND-Vario and PolarPro VND and softens detail slightly more; it is a variable rather than a fixed set like the Cokin Nuances Extreme.

PolarPro Peter McKinnon VND Edition II

The PolarPro VND uses hard stops like the NiSi True Color ND-Vario but adds pronounced haptic feedback the NiSi lacks; its 2-5 stop range matches the NiSi and is narrower than the Hoya Variable Density II, and it is a variable rather than a fixed set like the Cokin Nuances Extreme.
