Do I have to worry about the pinches on this lens (surrounded by red)? After I asked about them, if the lens was abused, the seller interrupted the communication. But I still want the lens
The seller changed the presentation image and now the lens looks better.
Is it possible to have some hidden defects, after a mechanical shock, hits, or not think so much and buy it and get it done? _________________ http://www.adlightstill.smugmug.com |

I would say those are minor scratches and won't affect mounting and dismounting the lens. You can ask the seller if pushing in the plunger stops down the lens iris and if the aperture ring and focusing collar turn freely.
If yes to all of the above, then I wouldn't worry about it. _________________ Michael

Is that an Auto Takumar ? Mine had a very sticky stop down mechanism from the switch on the outside that would stick the aperture in whatever position. The blades were fine, it was the levers and links. To get at them the black plastic disc has to be removed - and maybe that's why there are marks on the lens where the ring has been prised off?
I've got a very similar Auto Yashinon that also had a similar problem, but I can't remember if that has the plastic ring ( I'm away from home at the moment ) _________________ LENSES & CAMERAS FOR SALE.....

Looks like tool marks from a repair job.
Its often necessary to remove things like that plastic cover, in order to work on rear elements (clean fungus, etc.) and aperture blades. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Thank you for the answers. I do not worry about pinching now, but I worry about the professional way or not he crafted in the lens. _________________ http://www.adlightstill.smugmug.com |

Mine is missing the plastic shield. Inside the lens the brass actuator runs on a brass track. And this gets gummed up with oil that leaches from the helicoid grease, or maybe it was lubricated from the factory? My lens had perfectly dry and free moving aperture blades, but the movement of the actuator on the track was very slow, often it stopped. I used lighter fuel in a hypodermic syringe and managed to get tiny drops onto the moving actuator and track without soaking the rest of the lens, and that was good enough to clean the track.
