Hi I'm from Sri Lanka.(please don't mind my English)
Some kind of a fungus has started to grow under the front element of my 18-135 lens.http://www.flickr.com/photos/79575858@N05/7295434526/#
I sent it to canon and got amazed. Asked them If they could clean the glass.First they said NO.Then said they can give it a try but cannot be sure to clean it. And said if it needs further repair they will need to ship it to singapore and it will cost around 200$.
It is unbelievable how they will repair other expensive gear.I don't understand.
They asked for a week for inspection but I said no.
I keep my camera in a airtight container full of silica gel.Only guess is that temperature
is too low inside it.
Here's my question Now I have decided to take apart the front element and try to clean it.
also found this article describing about it. http://photography-on-the.net/forum/showthread.php?t=1167610
Will it cause misalignment?
Please can anyone suggest a good solution to use?
I thought I would use ammonia and hydrogen peroxide mixture but cannot find exact concentrations? Any Help will be welcome! Thanks.
