#KameKen Soligor 135mm F2.8 Konica F mount? Accessories: Front and rear caps There is dust inside, but the optics are in good condition. There is a slight bleed-like substance on the aperture blades, but there was no sticking when operating the aperture. As it is a preset aperture, it is likely a product from around the 1950s-1960s. Also, due to the shape of the external mount, I believe it is likely compatible with Konica's F mount. I do not have an adapter for the Konica F mount, so I have not been able to test it. Considering it is a product from 60-70 years ago, the condition is good, so please consider it. If you purchase multiple items, I can offer a small discount equivalent to the shipping cost by combining them. Please contact me before purchasing. I have confirmed there are no cracks or breaks, but I cannot guarantee against minor scuffs from manufacturing, shipping, or normal in-store display. Please understand that this is a used item. It is stored in a clean condition, but I will disinfect it with alcohol before shipping. This item is also sold at auctions, flea market apps, and in person, so it may be out of stock depending on the timing. Since the nearest post office is closed on weekends and holidays, if you win the auction during these times, shipping will be after the holidays. Thank you for your understanding.
