I picked this lens up with a camera that I purchased. It is a Tokyo Kogaku Professional Topcor P.S 10.5 cm f3.5. From what I understand this lens covers 6x9 but will not cover 4x5. The glass is clean and clear, anything in the photos is dust. The lens is in a Seikosha SLV shutter mounted on a small 3.5 inch lens board that I believe is for a Horseman camera. The shutter is STIFF to cock and definitely feels like it could use some lubrication but it fires smoothly on all speeds and sounds accurate. Aperture works fine. The flash sync is wired into the lens board. The lens came with three Kenko 40.5mm filters, an L39 (UV filter) and a PX2 and PX3 (close-up). I will include those in the sale as well. Based on recent eBay sales I am pricing this to sell at $150 but offers considered. $25 shipping in Canada or the US, others can contact me for an estimate.
