B+W 86mm T-Pro 010 UV Protection Filter

Good for down to 17mm Full Frame Format ULTRA-THIN T-PRO MOUNT - Probably the thinnest filter holder on the market! At only 86 mm, B+W Titanium mounts eliminate almost all risk of vignetting, even with large wide-angle and telephoto lenses. The titanium finish gives the thread a very special smoothness and at the same time increased robustness. Despite the thin mount, the Titan series still features a front thread for lens hoods and other attachments. MRC Nano Coating to Repel Dirt and Water
