Super-Takumar 55mm f/1.8 Lens This is a used item. Please understand that the following is based on my observations and should be taken as a reference. There are no noticeable scratches or marks on the exterior. As far as I can see, there is some dust inside the lens, but no mold, haze, or balsam separation. There are no noticeable scratches or marks on the lens surface. The aperture blades open and close normally, and there is no oil on them. I have checked and described the item to the best of my knowledge, but I am not a professional, so there may be oversights. I have checked the inside of the lens under fluorescent light. Please refrain from bidding if you are sensitive to such things or if you will claim that the description is different after checking with a strong light. I have confirmed the operation by attaching it to a camera body, but since it is an old item, no claims or returns are accepted. M42 mount. You can enjoy sharp and beautiful, creamy bokeh that you wouldn't expect from an old lens! I have attached photos taken with this lens for reference. The original lens cap is also included!
