NiSi ATHENA PLマウントレンズ用 ATHENA UV・IRカット リアPLフィルター

Installing this rear filter onto my ATHENA lens was incredibly satisfying—it clicks securely into place with no wobble, and the image now has noticeably richer blacks, especially under bright stage lights.

Finally, a rear filter that doesn't mess with my lens's back focus—threaded right in and felt solid. The UV/IR cut is subtle but I can see the difference in skin tones under mixed lighting.

I was worried about color shift with UV/IR filters, but this one keeps skin tones natural and clean. The rear mount design is a lifesaver for rigs where front filters get in the way.
