★★Please Read Carefully★★ (Price Revision) This lens is an L39 screw mount old lens. If you are using it with a mirrorless camera, please prepare a separate mount adapter. * Due to Mercari's specifications, I have to select something, so I have chosen Micro Four Thirds. I am selling this to organize my Industar-61 (L/D) collection. I have stored it in a dehumidified storage and handled it with care, but since it is a layman's inspection, no claims and no returns are accepted. It is almost like new with almost no scratches, but please refrain from bidding if you are a perfectionist. [Manufacturer] FED, made in 1988 [Product] Industar-61 L/D 55mm F2.8, 6 aperture blades [Mount] L39 Screw Mount [Product Condition] ■ Optics I think the optics are quite good. This lens is prone to dust and debris due to its structure, but there is almost none. It is almost invisible unless you shine a light on it. No mold. ■ Body: There are no particular scratches from use. ■ Helicoid: No particular problems. Infinity focus was achieved. ■ Aperture: No problems with the click feel or blades. ■ Accessories Please consider the accessories as a bonus. Front cap (with scratches, but FED made), rear cap (with scratches) ■ Trivia There are several focal length markings on the Industar-61 (L/D), such as 52, 53, and 55, but they are all incorrect; the correct focal length is 52.42mm. When performing manual image stabilization, please be careful with the focal length. I had five Induster-61s, but I found a very rare one with a zebra pattern / distance scale in feet / 10 aperture blades, so I decided to let this one go. It's a common black 6-blade aperture, but the condition is good, so please add it to your collection.
