simply rotate the filter rather than switch it out

This makes it impossible to use the same 3mm thick frame as the smaller sizes

It allows you to color correct and enhance colors without needing to compensate for light pollution

Hoya Variable Neutral Density Filter 1.5–9 Stops vari-ndx simply rotate the filter ratherDescription The Hoya Variable Neutral Density Filter provides a way to maintain exposure control by varying the amount of light entering the camera by 1. 5 to 9 stops (0. 45 to 2. 7 density for cinematic use). The precision built in double ring design allows the outer ring to rotate to control the amount of neutral density effect anywhere within the 1. 5 9 stop range. This double ring design is thin to reduce the likelihood of vignetting with wide
