I just picked up a working Yashica Electro 35 GSN. Near mint, and it works, meter and all. The lens is the 45mm 1.7 Yashinon DX. I've always wanted an old rangefinder in working condition, now I have it. I just replaced the light seals.
But, there is an annoying dust speck inside the lens, stuck to the glass. If it were the size of a pinpoint, I wouldn't worry about it too much. But it's larger than that, and who knows, there's probably more dust in there than I can't see on a casual inspection.
A little bit of dust is something one can live with? Or is it going to affect the picture quality noticeably?
I haven't run any film through it just yet. I just got it a week ago.
How hard is the lens on this camera to tear down? |

How much larger? If you can unscrew the nameplate ring (black) around the lens, you can then screw the front element group-if the speck is INSIDE the front element group, as opposed the being on the rear surface--it can be more of a problem. As far as bothering the pics--unless it is exceptionally large--it will probably bother you more than it does the pics. |

Well, much larger than a pin point, but quite a bit smaller than a pin head. Plus, I can see more in there, smaller specks.
But, it appears to be between the aperture blades and the rear element. |

Don't worry about it. I've got a GSN with a wicked scratch across the front of the lens; it doesn't show at all. |

It is unusual that dust in a lens is concentrated in specks. Are you shure that it is no fungus? Fungus has different appearences. One of them is the concentration in specks of the described size. If it is fungus you must clean the lens. Not because of imaging issues but because fungus will grow over time and etch the lens surface. However it grows slowly. One method of killing fungus is UV light. You migth expose the lens to sunlight for an attempt to kill the fungus. |

No, it's not fungus. I know what fungus looks like, and it's not that.
I'll just use and enjoy the camera, and see what the prints come out like. If Donnie has one with a wicked scratch and it doesn't show on the prints, a few dust specks will probably be OK on mine. |
