My step-sister found her old Canon EOS 850 body and lenses today and let my Mum have them in case they were any use to me. I've just got the 100-200mm lens out and there's mould under the front glass. Is there any way I can rescue this or is the entire lens now bin fodder? There's also a 35-70mm lens which seems fine, help!
 
Try it and see wether it affects the image. There are lots of remedies on google but they don't always work. I read one where a guy just left the lens out in the sun for a day...
 
I'll try that then. Just been speaking to a mate who says it's a poor lens both build wise and optically, and not really worth using. It's the 4.5
 
I've left it in the kitchen window with the cap off, I've had a quick look online but can't really find any suggestions. Anyone got any bright ideas?
 
Have the lens serviced? Probably still cheaper than a new one.
 
But is it worth it? Is the lens any cop itself? I'm planning on ordering a Canon EF-S 55-250 tomorrow and thought I might keep it purely as an emergency measure but if the lens itself is pants is it worth spending any money on?
 
Have you tried using it yet?
 
dosent seem to be anything wrong with that its a keeper

Dunno if its my imagination, but I thought there was some haziness on the left hand side of the pictures. :shrug:

On the second image on the car section of the image I can notice a slight haziness as well. Not sure if its that significant though? Still looks worth keeping the lens :D
 
If it were me (and if you have bought a replacement), I'd just bin the old lens off. I don't know what type of mould it is, but mould/fungi produce spores, and the last thing i would want to do it increase the risk of it being spread to new lenses.

ps, don't panic, as I have no idea if cross lens contamination has ever occured, but I am a microbiologist an it's the first thing that popped into my head. Maybe have a google on the subject.
 
I've never tried taking a lens apart, but I've seen photoblogs of people doing it on various lenses, maybe try to find a step-by-step guide, afterall you've got nothing to loose.

Can I take it apart and clean it myself? It's a freebie, afterall.

If your brave enough, if it doesnt have significant value to you, and you are sure that you can reassemble it correctly then I don't see why you couldn't. I might be totally wrong here so dont go on just my word! :lol:

not to use on an eos850 you're not. thats a 1988ish vintage with an ef mount :nono:
an efs lens will only work on an aps camera, or an dslr with an aps size sensor, the rear element of the lens sticks out too far, and will be whacked by the mirror :eek: :rules:
 
I have heard that if you seal the lens tightly in a plastic baggie, and put it in the freezer for a few days, it'll kill the spores. The fungus will remain, but the spores will be dead, and therefore can't spread.
 
If you don't want the film camera or any of the lenses... i'm sure a home can be located for them, DON'T actually bin them, pass them on to a less fortunate person with an interest in photography.
