Hi,
There's quite some dust particles in my Zuiko 85mm lens. I believe it's on the surfaces in front of and behind the diaphragm, because that is the only place where dust can get - through the diaphragm mechanism.
I was able to unscrew the 2 blocks: the rear (focusing ring), and the front (optical block), but I don't know how to get to the aperture. There is the mechanism of the rear floating group... and I think if I could remove the rear group with its mechanism, I could clean the dust in there...
This is picture of the rear of the lens after removing the bayonet:
and here after removing the all the guides:
Sorry I didn't take a picture of the rear when the focusing ring was removed...
Please, I'd like to know how to get to the aperture. Do I have to go through the front? Or can I just somehow remove the rear group? Please help. |
