فلتر عدسة Promaster 72mm Variable Neutral Density

I've been using this variable ND for landscape shots and the ability to dial in exactly 3 stops of light reduction is incredibly handy. It smoothly transitions from subtle to heavy darkness without any color cast, even at the denser settings.

Finally, a filter that actually lets me dial in the exact exposure I need without swapping glass. The smooth rotation ring on this one is precise enough for subtle adjustments in changing light.

The variable range from ND3 to ND400 is honestly the only filter I need for outdoor shoots now. Twisting the ring from one extreme to the other is smooth, and it saved me on a bright beach day where I'd have otherwise blown out the sky.
