    Steaming up Lens'....??!!

    Twice since I've come back to NZ from overseas I've had 2 of my Lens steam up inside, my 24-70 L and 16-35 L. The 24-70 would make sense as I did use it in the rain in Hong Kong but since its both of them... hmmm...

    The other photographer shooting a show with me last night checked it and suggested it could be that the lens was freezing cold and the venue was really hot.

    So do L lens steam up if the environment change is severe enough? These lens have performed flawlessly until I started storing them in my Lowerpro backpack. Maybe they're coming out too cold?

    Uh-oh, that's an issue! I always thought better about hydraulic insulation on these Ls. Take measures immediately - put the lenses in a hermetically sealed plastic bag with some kind of dehydrating agent, fresh silica gel or rice dried in a hot skillet (not fried). That would take the mist out of the lens in a day or so. If it stays there for long enough, the prospects are not too bright

    I am no expert on Canon law. It does seem to me to be a L of a situation.

    I would follow the advice of Mr Kulikov.

    Pharmacy's often throw out lots of these little packs., They're used to keep pills dry. Ask your friendly pharmacist, he/she will likely be happy to give you some.

    If you have lenses that are steaming up on the inside with normal use, they need to go back to Canon and be checked out, this is not normal and normally means the intergrity of the lens has been comprimise, I would get a hold of your local Canon dealer and see how they may be able to help, if not them, then get a hold of Canon, in a almost sealed enviorment such as is in the modern lenses of this nature, your opening yourself up to having fungus form on the inside of the lens, which would be expensive to get repaired.

    I find myself sort of intrigued. You do not have access to rice, a heat source and a frying pan? Ask your girlfriend for help and then try to find a nice way to repay the favor.

    Hi Dave, yeah I am worried about the mold in the lens but I'm off to NYC again in a few weeks and dont have time or can't chance having Canon look at my lens and not get them back to me in time. I need my 24-70...!!!
    Hmm rice in a hot skillet... must have some somewhere... or i might just go visit a h/w store and get some silica it'll have to do for now I guess.
