Promaster 9524 62mm 可變ND濾鏡（1.3-8.6級）

I was pleasantly surprised by how smoothly the ring turns for adjusting the density, and it held its position well once set. The 1.3-8.6 stop range let me keep my aperture wide open even in bright sun, which gave me the shallow depth of field I wanted.

This variable ND filter gives me consistent, neutral color from 1.3 stops all the way to 8.6 stops, which is rare. I’ve been using it for video work and the rotation is smooth with no annoying hard stops. Really pleased with the build quality for the price.

Finally a variable ND that doesn't introduce a nasty color cast when I crank it past 6 stops; the 62mm threads onto my lens perfectly and the ring action is smooth without being loose.
