B+W 1097732 49mm Clear Filter T-PRO HTC

The B+W 1097732 T-PRO Clear Filter is built for photographers who want to protect their front lens element without introducing any optical penalty. Unlike UV filters that also absorb ultraviolet light, this is a purely clear protection filter — its job is to act as a sacrificial barrier against scratches, dust, moisture, and accidental impacts. The glass itself is designed to be optically transparent, adding no color cast, haze, or sharpness loss to your images.

What sets the T-PRO line apart from basic protection filters is the engineering of the mount and coating. The slim-profile brass ring with a reflection-free titanium-color finish minimizes the chance of vignetting, making it compatible with full-frame lenses as wide as 17mm. The MRC nano coating is applied to both sides of the glass and causes water and oil to bead up and roll off, meaning fingerprints wipe away quickly and rain droplets don't cling to the surface. For a 49mm filter thread, this makes it well-suited to compact primes and mirrorless lenses where the front element is particularly exposed during everyday shooting.
