Promaster 82mm サーキュラーポラライザーフィルター (CPL) - Basis

I was skeptical a cheap CPL would make much difference, but the contrast boost on a cloudy day was immediately obvious in the sky and foliage. The ring turns smoothly and locks tight on my lens, and reflections off a wet sidewalk disappeared completely.

Finally a filter that actually cuts through water reflections without washing out the whole image. I noticed the colors in my landscape shots are noticeably richer and more saturated right out of camera. The rotating ring is smooth enough to fine-tune the effect without feeling loose.

I was tired of fighting glare on glass and water, but this filter cuts reflections beautifully without adding a weird color cast. The contrast and saturation boost in my landscapes is subtle yet noticeable, exactly what I needed.
