B+W 1097730 43mm T-PRO Clear Lens Filter

The B+W T-PRO 43mm Clear Lens Filter is a permanent lens protection solution built for photographers who won't accept optical compromises. Unlike entry-level clear filters that introduce reflections, ghosting, or measurable light loss, the T-PRO's optical glass is coated with 16 individual MRC Nano layers — each targeting a specific wavelength range to suppress surface reflections and maximize transmission. The result is a filter that sits on your lens without announcing itself in the final image. The ultra-slim titanium-colored mount keeps the stack height low enough for full-frame wide-angle coverage down to 17mm, a threshold where standard-depth filters begin to cut corners into the frame.

This filter is built for photographers who keep glass on their lenses in all conditions — wedding and event shooters navigating champagne splashes and humid venues, travel photographers working in dusty or rainy environments, and portrait photographers who'd rather spend a second wiping a filter than risk a scratch on a coated prime. The MRC Nano surface sheds water and fingerprints with minimal effort, and the titanium mount ages better than brass under repeated cleaning. It's a small, unglamorous piece of gear that earns its keep by quietly doing nothing — which is exactly what a protective filter should do.
