There is this funny camera guy on Youtube, The Angry Photographer.
He owns a ton of Nikon gear and uses profanity as his trademark. Of course, English profanity is so mild in Finnish standards, that my mother in law would think it is school girl talk, only if she could understand it.
Well, The Angry Photographer if somewhat funny to watch, though he could cut down the length of his presentations to 1/10th of the time he is using repeating f-words and giggling.
I was watching this piece yesterday.
Oh no! I was so shocked to hear, that you should NEVER breath fog on your lenses to wipe them clean. What? Everybody does that. But what really shocked me was, that he said human breath contains harmful acids, that will damage multi-coating of the lenses front element (go to about 1:40 if you don’t want to watch it all).
Of, my! I have been ruining my lenses!
But wait! Were does the acid come from, if you don’t vomit on your lenses (don’t do that, bugger). Human breath should be mostly atmospheric gases, with less oxygen plus some added carbon dioxide and water. Carbon dioxide dissolved to water can be acid, but other than that I would think the fog condensed on your lens from your breath should be practically water, not much else.
Come on, Angry! Though you probably know more about Nikon lenses than I do (and thank god for that), I was breathing on my lenses even before you even needed diapers!
So, what I think is that The Angry Photographer is spreading an other urban legend.
There is nothing more I hate, than a false piece of information disguised as a fact, but is actually just hearsay. Even if spread inadvertently, I cant stomach such an abomination.
Well, we all do that, don’t we (and that’s why I hate it!). So it’s not a big deal, I forgive you, Angry Protographer, and may still watch you videos when I feel somehow inferior and need to know I am not the biggest deuchebag on the planet.
But hey! maybe I am wrong and the acid in human breath really eats through the multi-coating of your lens. If anyone can prove me this is true, I am happy to learn being wrong again and learn new things.
So, true or not, anyone?
P.S. It appears from Internet, that Nikon may have been the source of this piece, but they have since removed the advice not to breath on your lenses from their website.
Update: Here is a post discussing the “acid breath problem”
Nikon had the “acid breath” warning removed from their website shortly after.
Update 2: Found someone else calling bullshit on Angry Photographer:
Update 3: Ken Wheeler, alias Angry Photographer, calls bulshit on Richard Feynman, QED, and claims to be the only person to understand magnetism!
Whoaa! He is so cute! And he owns a shitpile of Nikon lenses! And can explain magnetism! And has an acid breath!
I think this case is closed.
