Sigma 77mm WR Ceramic Protector Filter

Was a bit skeptical about ceramic filters, but this one is shockingly clear — I honestly can't tell it's on the lens. The scratch resistance gives me real peace of mind when swapping lenses outdoors.

The water-repellent coating works exactly as promised, raindrops just bead up and roll off instantly. I’ve had this on my lens for a few weeks now and can’t tell it’s there, yet the front element feels much safer.

Was skeptical about spending this much on a clear filter, but the 99.76% transmittance is no joke — my images look exactly the same with it on. The ceramic construction feels much tougher than my old glass filters too.
