Okko Pro / Variabel grijsfilter 67mm

I was a bit skeptical about variable ND filters, but this 67mm model has made dialing exposure adjustments so much quicker on my wide-angle lens. The stepless control lets me smoothly go from a subtle darkening to a heavy 10-stop reduction without swapping out filters.

The ability to dial in exactly the right light reduction without swapping lenses is a game-changer for my outdoor shoots, and the ring rotates smoothly enough for quick adjustments between shots. It's become a permanent part of my kit bag.

Swapping between f-stops mid-shot without unscrewing anything is such a time-saver on location shoots. The ring turns smoothly and locks in place firmly, so I never worry about it drifting when I’m adjusting the composition. For the price, it’s replaced three fixed NDs in my bag.
