B+W 58mm Circular Polarizer

The brass ring threads onto my lens much smoother than any aluminum filter I've used before, and it doesn't bind at all. I was surprised at how much richer the greens and blues look in my landscape shots without any weird color cast.

Used it on a sunny day and the sky really popped without any weird color cast. The pro mount is thin enough that I didn't see any vignetting even at 24mm.

The brass ring threads on like butter and the whole thing feels rock-solid compared to my old plastic filter. Used it on a bright coastal shoot and the sky popped without any dark corners, even at 16mm.
