BRAUN Blueline UV-filter 40,5 mm

The glass is noticeably clear when I hold it up to light, and it threaded onto my lens with zero wobble. For the price, this feels like a solid upgrade over the cheap filters I've used before.

I needed a slim UV filter that wouldn't cause vignetting on my wide-angle, and this one fits perfectly without any dark corners. The multicoating is doing its job—no extra flare in backlit shots.

The glass is surprisingly clear for the price, and the filter rings onto my lens without any wobble or sticking. It’s done exactly what I needed for keeping dust off the front element during a dusty shoot last weekend, and I’ve noticed zero impact on image sharpness.
