Dorr 77mm 環形偏光 Digi Line 薄框濾鏡

Took this out to test the reflections on a lake and the circular polarizing effect really made the sky pop without any weird color shift. The slim ring threads smoothly on my lens, and for a budget filter it feels sturdy enough for everyday use. Just wish it came with a case, but the performance alo

This slim profile filter is perfect for my wide-angle lens since it doesn't introduce any annoying vignetting. The rotation feels smooth and precise, and the color saturation boost in my landscape shots was immediately noticeable for such an affordable price.

Doesn't feel like a budget filter when you screw it on; the rotation is smooth and the glass is optically clean. I got it to cut glare on wet rocks and was pleasantly surprised by the lack of color cast. Only niggle is the front thread is a bit tight for stacking, but that's a minor thing.
