Here is my Kiron (vivitar) 105: first look, aside from dust, looked good: http://farm6.static.flickr.com/5296/5408006681_a9506d54d0_z.jpg http://farm6.static.flickr.com/5251/5408006767_eb3cc89503_z.jpg but at closer look, the second element (ithink) from the mount: http://farm6.static.flickr.com/5296/5408006615_29a979312b_b.jpg What is it? Worth a CLA? DIY difficult? TY sirs |

That, is a case of the fungus. Depends on what you paid for the lens, sentimental value, etc on whether you want to tear it down to fix. Soaking the element in Ponds Cold Cream, or in a 50/50 mix of Hydrogen Peroxide/Ammonia for hours or days is the recommended method. But the fungus could have etched the surface of the element beyond good use. Then it might make a good soft portrait lens, even without the fix. PF |

It might be fungus; I can't say for sure. It might be oil spots. Either way, I'd have it looked at; it should be removed. I haven't worked on a Kiron 105 so I can't offer any advice on DIY repair. |

PF, what makes you so damn sure, just by looking at Uhoh7's picture postcard, that what you believe to be seeing "is a case of the fungus"? Uhoh7: Before doing anything else read this first: https://kyp.hauslendale.com/classics/forum/messages/20735/16849.html Whoever invented this odd and vague story: Pond's Cold Cream is good for your skin, perhaps, but definitely NOT for lens surfaces. |

The cold cream myth seems to have originated on manualfocus.org, it doesn't make any sense at all. Rinsing with water and dishwash liquid will remove the fungus, any etching to the glass will depend on how long the fungus has been present and the type and quality of the coatings. A wipe with hydrogen peroxide solution will sterilize the surfaces. |

ty for all replies. I've had the pics at several MF forums, they all think it's haze or dried oil, not fungus. I send for CLA, since the rest is totally mint. Paid 122USD last fall. |
