NiSi ATHENA True Color ND-Vario 0.3-1.5（1-5級）ATHENA鏡頭專用插入式濾鏡

I was skeptical about variable NDs, but this one maintains true color across the entire 1–5 stop range, with no weird color casts in my test footage. The drop-in mechanism snaps right into my lens without any shifting, which is a huge time-saver on set.

Screwed it into my cinema lens rig and was shocked by how smooth the rotation feels—no hard stops or color shifts as I dialed through the stops. Really appreciate that it covers 1 to 5 stops in one compact drop-in, saves me swapping filters on set.

The color accuracy is genuinely impressive across the entire 1-5 stop range, with no weird green or magenta casts I've seen in other variable NDs. It clicks into the lens housing perfectly and saves me from constantly swapping screw-on filters on set.
