I'm not sure of the details as these belonged to my grandfather. Lens Filters - Set of 8 NO2 Close-up 34mm L37C 52mm x 2 ND 4X 52mm A2 52mm (for cloudy/shady conditions) Y52 52mm R60 52mm L1Bc 72mm Close-up NO1 52mm (This one only has a Kenko case) They are quite old, so as shown in the images, there is some cloudiness and dirt on the lenses. I don't know how to clean them, so I will ship them as they are. Please refrain from purchasing if you are concerned. Immediate purchase is welcome. No individual sales or price reductions.
