B+W 1097739 72mm Clear T-PRO Lens Protection Filter

The B+W 1097739 72mm Clear T-PRO Protection Filter is engineered for photographers who want uncompromising lens protection without any optical compromise. Its clear glass element, treated with 16 layers of HTC (High Transmission Coating) and a final nano layer, transmits light with virtually zero loss and no color shift, ensuring the filter can remain on your lens permanently without affecting image quality. The nano coating serves a practical purpose beyond optics — it causes water to bead and roll off, prevents dust from adhering, and makes fingerprints easy to wipe away, keeping the filter clean during extended shoots in challenging conditions.

The T-PRO mount is constructed from brass with a reflection-free titanium-colored anodized finish, combining durability with resistance to internal reflections that could contribute to flare or ghosting. Its ultra-slim profile is specifically designed to prevent vignetting on full-frame lenses as wide as 17mm, making it a practical choice for landscape and architectural photographers who frequently shoot at wide focal lengths. Front threads on the mount allow stacking of additional filters when needed. For anyone invested in quality glass, the B+W T-PRO Clear filter offers a reliable, optically invisible layer of physical protection that stands up to everyday use and adverse shooting environments.
