I'll be changing cameras, so I'm also selling my lenses. I'm also putting my filters up for sale. I haven't taken many landscape photos, so they've been stored in a dehumidified storage box. The PL filter itself is in almost new condition, with no scratches on the lens or the frame. However, the S (screw-type) filter is designed to be extremely thin, and due to its specifications, the frame is quite stiff and difficult to turn. There's almost no "side" like on a regular filter. You have to hook your finger on the top to turn it. To be honest, that part is a bit difficult to use, but it's extremely thin, so it's suitable for ultra-wide-angle lenses.
