The Fuijifilm PRF-49 protector filter is a simple, clear filter with a 1 x filter factor that is designed for general lens protection on select Fujifilm fixed lens cameras as well as any other lenses with a 49mm filter thread. This optically clear filter will reduce dust, scratches, moisture, and other damage to your lens without affecting image quality. The PRF-49 is multicoated, including Super Electron Beam Coating, to minimise ghosting and flare, which permits greater light transmission and colour reproduction. Compatibility: XF 16mm f/2.8 R WR X70 X100 X100S X100T X100F X100V (Note: An adapter ring, AR-X100, which is included with lenshood LH-X100, may be required to attach filter)
