XT996 PRO BLACK FRAME LENS PROTECTION FILTER
<p>The XT Filters XT996 PRO is an optically near-invisible protection filter: it shields your front element from dust, scratches, rain, and fingerprints while leaving color, contrast, and sharpness untouched. Average transmission is about 99.6% with average reflectance down to roughly 0.08%, so it can stay on the lens full time.</p><p>The black anodized frame suppresses stray reflections inside the filter mount, backed by a double-sided 36–48-layer multi-coating. Sizes run from 34mm to 105mm, including dedicated 39mm Leica and Fujifilm versions, a 46mm Leica version, and a 49mm version that fits the Leica Q3 43.</p>
