NiSi SWIFT 67mm True Color ND-VARIO Pro Nano 1-5 Stufen variables ND

I’ve been using this on my 67mm lens for landscapes and the seamless 1-5 stop adjustment is so smooth that I no longer worry about color shifts mid-shot. The build feels solid and the ring turns just the right amount of friction to keep it in place.

I was worried about color cast with a variable ND, but this filter keeps the image neutral across the whole 1-5 stop range. The build quality feels solid, and it's been perfect for balancing exposure in bright daylight without carrying multiple fixed filters.

The ring rotates smoothly with just the right amount of resistance, making it easy to dial in exactly the right density for changing light conditions. No color cast even when I crank it up to 5 stops, which is a huge plus for my outdoor shoots.
