I bought a Pentacon 135mm F2.8 today, the 15 blades blinding me to the haze?/fungus? on the glass. It takes photographs but I'm wondering if I can dissemble the front and rear lens elements easily to clean the glass. It would be nice to know that the lens will then perform nearer it's original potential.
Both elements have what appears to be slotted and threaded rings holding them in. I have not yet tried to undo these as I see there are "lens spanners" on Ebay and might just order one if the removal of the glass is easily possible.
I have a zoom lens with fungus that will also be tackled at a much later date but only when I have a success or two with simple cleaning. Next up will be a Pentax 50mm F2. If I get this Pentacon done.
