Re: HELP - Need advice with a potential problem
From: Patrick Genovese [EMAIL PROTECTED] He got the lenses to my place and upon looking through the viewfinder I was horrified to see that the lens in question seemed to be fogged. Upon closer inspection the lens seemed to have quite a bit of dust and fungus growth inside. The lens did not stay on the body for more than a couple of minutes coz I immediately took it off. I am worried that I may end up infecting my own lenses with fungus.. What you see on a camera lens is the growing part of a fungus. It is not (generally) infective itself. What causes fungus on lenses is suitable conditions for the germination of fungal spores. Virtually every cubic centimetre of air carries fungal spores. Granted, if the fungus on the lens has started to produce spores you may have increased the concentration of them in your vicinity. If your lenses are kept in dry conditions and regularly exposed to light, it is highly unlikely that you will have produced the conditions for germination. Your lenses, in all probability, were infected (filled and covered with spores) a long time ago. - Email sent from www.virginmedia.com/email Virus-checked using McAfee(R) Software and scanned for spam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Germs are everywhere...all around us...unseen...silently infecting us. Indeed. We are eminently suitable breeding grounds for all sorts of things but we are very good at fighting them because of that. Lenses aren't any good at fighting at all. But they are very hostile environments for things to grow on. Keep them that way and you will have little trouble. - Email sent from www.virginmedia.com/email Virus-checked using McAfee(R) Software and scanned for spam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: HELP - Need advice with a potential problem
Actually the infected lens is not mine it just spend a couple of minutes on my K10D. I took Paul's advice and cleaned the mount and body cap thoroughly hopefully that should be enough. I found some information on-line reccomending a wipe down with hydrogen peroxide then alcohol . Ive done that and I guess all I can do is hope for the best. Actually none of my lenses have ever had fungus on them. One of the older ones has a little bit of dust inside but other than that i've never had any such problems.

Re: HELP - Need advice with a potential problem
I wouldn't worry about it, although i might wipe the lens mount with a towel dipped in bleach. But be careful not to get bleach on the plastic. That lens might be recoverable too. Tell your friend to take it to an expert camera repair shop. If the coatings haven't been etched by the fungus, it can be fixed. I have a beautiful lens that I bought for next to nothing ten years ago because it was fungus infected. It was disassmebled and sterilized by a pro. It came back perfect, and has worked flawlessly ever since. Paul -- Original message -- From: Patrick Genovese [EMAIL PROTECTED] Hi, A friend of mine is thinking of buying a pentax DSLR and wanted to try a couple of old F Series lenses on a K10D.

I've never had a lens with fungus on it so I don't have much experience in this regard. It's unlikely from that short an exposure, I think, but you never know until it's too late. If you are nervous, a gentle and thorough blowing out of the mirror box would certainly not hurt. Use it as an excuse to clean the dust off your sensor.
