Kenko Lens Filter 44.5mm s.c KH1/18 UV Silver Frame No apparent mold to the untrained eye. Some wiping scratches are present. Please consider that there may be other deterioration due to the item being used. Used with Nikkor Q.C 13.5cm f3.5 (S mount). This appears to be a retro silver-framed (chrome finish) UV (ultraviolet absorption/lens protection) filter, mainly used in cameras from the 1960s to 70s (especially Olympus Pen series and some Japanese compact cameras). I am also listing other camera accessories. Discounts are available for combined purchases. Please comment if you have any questions. #LensFilter_Korosuke #46mmLensFilter_Korosuke #CameraAccessory_Korosuke
