Hi. Thanks for the ideas. I am not bothered necessarily about physically getting rid of it, you have to turn the thing around in the light to see them and they are invisible when actually using the viewfinder. I just want to kill the fungus so (a) it doesn't get any worse and (b) removes any possibility of spreading to other kit. (I know that some have argued that it shouldn't happen as the spores are in the balsam glue but I'd rather play safe!) I'll look into the ultraviolet idea. We'll probably have some UV lamps in the lab at work.

Many thanks, Kris.

I have recently picked up a FC-1 viewfinder for my LX. Sadly, it has a slight fungus problem. I knew this when I bought it but the FB-1 base is in immaculate condition and it wasn't a bad price. Is there some way I can kill the fungus so it won't spread without taking the thing apart? Is it even possible to take the thing apart?

Many thanks, Kris.

I can back you up in the sense that I do not have any MZ-3s in my database! It is, however, the highest spec MZ short of the MZ-S. I would heartily recommend Harrow Technical who have done sterling work in my ME-F and LX and will shortly be getting an ME Super and an MX to service. Your local camera shop will probably just say they cannot get the parts which is what happened to me.

How much are you thinking of selling for John :

You can pick up replacement focus screens on ebay now and again. I doubt you'll be able to clean them as they scratch very easily. See Bojidar's website for the part numbers.

Cheers, Kris.

I don't think I have ever used the AE-L button. If the metering is that fiddly I use manual.

I don't mean to be rude but did you seriously miss the joke, or are you just winding us up (if you'll excuse the phrase!) :

Sounds like a good time to start buying 645 lenses off ebay...

Very useful article. Nice to see the K20 up there with the top-end Nikons etc

Perhaps this post should be made a sticky in the lens section because it is an old chestnut we have seen discussed on here plenty of times.
