مرشح NiSi ATHENA Full Spectrum FS ND 0.3 (1 Stop) الخلفي PL لعدسات ATHENA PL

I love how this rear-mounted filter lets me dial in exposure without touching the front elements—perfect for keeping my lens hood setup clean. The 1-stop ND is subtle but exactly what I need to open up the aperture in bright light.

Slapped this on the back of the PL mount and the 1-stop cut is perfectly even, no color shift at all when I checked the waveform. The rear placement keeps the front element clean and makes swapping between lenses a two-second job. Exactly what I needed for matching exposure across my set.

Finally a rear filter that doesn't introduce any extra flare or color cast—the 1-stop ND is perfectly subtle. It threads in smoothly and stays secure, which is a relief when swapping lenses quickly on set. My footage looks cleaner than with a screw-on front ND.
