I have a IIa that seems great except for one or more hazy lens elements. How do I get at the lens cells, particularly in the front? I'm hoping I don't have to get into the shutter to do so. Thanks. |

The front cell just unscrews out of the shutter with your fingers. As for getting to elements within the cell, I've never done that ... but there are 2 tiny little screws in the back of the cell that may prove enlightening. |

Thanks, Rick. So how to get to the front cell? The reeded edge (like a quarter) chrome ring at the front of the lens doesn't seem to budge when I try unscrewing it -- that seemed like the obvious place to start but I don't want to force it. |

if you get a good enough grip, that unscrews. Try putting on a rubber glove, like the ones made for washing dishes... that will probably give you a good enough grip. |

Thanks, Rick, we'll give it a try -- I have a strap wrench also that I've used for loosening filters. |

I followed Rick's advice and indeed, a strap wrench works wonders. But once I got the front cell off and loosened the set screws to separate the frontmost element from the second group, it became clear the haze is inside the second group -- and I see no way to separate that. Oh well -- I've gotten good results from lenses that are far worse! |
