Thank you for viewing this listing. This listing includes the following: ・Leica Leitz Hektor 13.5cm f4.5 lens ・Rear cap Although "α E-mount" is selected for listing convenience, it is actually an M-mount. Both operation and function are problem-free. The aperture ring and focus helicoid are both smooth. I believe there are no major scratches, mold, or clouding, but some very minor dust and debris can be seen. Please understand that I cannot specify the exact type of dirt as I have not inspected it with specialized equipment. Based on the serial number, it is highly likely that it was manufactured in 1954. I think it is in good condition for its age. When using the lens, I used a lens filter, and when not in use, I stored it in a dehumidified storage unit with an anti-mold agent. Please understand that this is a used item, and the above content is based on the subjective opinion of a non-professional, and purchase accordingly. In principle, returns are not accepted, but please consult if there is any discrepancy with the above description. Thank you very much.
