You would need to fully disassemble the lens to do this as microwaving metal objects is not a good idea. I think the UV light from the sun would be the easiest method. Did they give a reason why only 30 mins? |

Yes. So that the lens doesn't overheat. It can damage the lens (as leaving one a couple of hours on the sun probably would). Note that they recommended this for the lens that show NO fungus as a precaution. The one with visible fungus must get the full treatment...disassembling, cleaning, ultra-sounds, reasembling...

Welcome to Dyxum Steve.
Brilliant idea! Especially those which have the 'hi-intensity' pods. Remember though that this will affect only the visible fungal spores and not those 'tucked away' in helicoids etc. |

No Biggie,
But one should consider that the fungus just loves the glue between doublets, and just about every lens has a doublet, so thinking I can clean this, is often those "Famous Last Words".. Fear the Fungus been there, done that.. regards fo Edited by fophotofile - 02 April 2009 at 21:54 |

Not that I've had any problems, but how easy is disassembly of more modern models? I ask out of curiosity, but in theory could you do the same thing with a lens made in the last few years?

So leaving my lenses out everyday for about 30 mins everyday, will help reduce fungus ??
I think ill start doing this, my lenses are always left in their cases with UV filter and both caps on, is there anything wrong with this, fungus wise ?? |

I have "something" in the Minolta 16/2.8 that I just bought
![]() Not sure if this is a small fungus or a thick dust. What do you think? |

Strange to see one isolated 'fluffy' bit like that. It might just be 'big dust' and well worth a clean.
If you just purchased it, I would have a word with the seller. |

I bought it online. The seller says it's "just a big dust". I not sure if I should return the lens.

A number of years ago my old SLR 35mm film camera equipment got fungus in the lenses and body. I did attempt to try and resolve the fungus problem by placing in direct sunlight for about 30min a day, but the infection was gone too far. (I loaned the camera to a friend who lived in a rain forest area and the infection got too bad in about 3 weeks) The age of the equipment and replacement costs used made it not viable to clean.
Anyway now for future prevention I use Silica Gel packs that have a heating element in so when the gel needs to be dried, I can plug it in direct to power and these are then dry ready for the next session, drying time can be between 4 - 10 hours. They are affordable and easy to use. For the Dyxum members in Australia, the dehumidifier versions that are dried by connecting to power are available through Bunnings for about $50. Also silica gel available link below and in bulk volume if required. dehumidifier Silica Gel Regards, Craig |

I went to a couple of 2nd-hand shops to get an opinion. It's only a large dust.
