Do not breathe on lens when cleaning!

If they're that delicate I think it'd push me towards Sigma :D Assuming you can breath on Sigma's :D
 
Do people still take acid? :shrug:
 
Thinking about it... some peoples breath could stop a charging rhino so maybe Nikon have a point.
 
Just being cautious if you ask me. Technically this is true, but it is true for all lenses, not just nikkors.
 
Reminds me of a sketch I saw somewhere, I think it was a professional training vid...

"You've been using this, haven't you!" Or in this case... "You've been breathing!"
 
I agree I think this is just over cautions. The time your breath stays on the lens is surely nit long enough for these acids to work?
 
I always, brush my teeth, floss and take mouth wash, before cleaning my lens :lol:
 
Less damaging than salt spray, I presume seascapes are a no no for Nikon users then, and as for changing a lens, must only be done in a sterile clean room under strict supervision :D
 
In a world where mc Donald's are obliged to put a warning n their apple pies informing you that the filling may be hot, Nikon are just protecting being overly cautious. I'd ignore it. My oldest nikkor lens was bought new, by me, in 1983. The coating if fine, and I've also breathed on it to clean it times beyond count.
 
Sounds like Nikon are just covering their a**. It's one fewer thing people can sue them for if things go wrong...
 
Lenspen reccomened breathing on the lens to remove stubborn watermarks.
 
Breath in healthy adults seems to be, on average, slightly alkaline.

Saliva varies from (values are approximate and exclude extreme conditions) ph 6 (slightly acid) to ph 7.4 (slightly alkaline). Ph neutral is 7.

Corollory: Nikon san, he talk borrocks.
 
Sounds like Nikon are establishing another reason to deny warranty repair on top of water and impact damage.
 
Also, 'looking through a lens too hard' will now invalidate warranty as this will cause photons to impact the elements harder that was allowed for in design parameters.
 
I've heard that it's much safer for the lens if you don't let any light travel thru it :)

Lets be honest, the safest way to protect your lens is to put the lens/end caps on, pack it snugly in its provided case, zip case up and place somewhere dark, moderate temperatures, dehumified and shock proof. That should do it :D
 
Well acid rain is a lot more harmfull than the tiny acid content of the average persons breath, maybe time to improve the coating to make it resistant to "normal" wear and tear".
 
I'm glad, that kissing your Nikon isn't mentioned to cause any problems...

It's not Nikon service you need for that but a visit to your local mental health team :)
 
People have been cleaning lenses by breathing on them and using their T shirt or whatever for donkey's years. All my Nikkors are old, metal bodied, MF lenses and I must have done this hundreds of times. Probably not the best method, but I wouldn't get too agitated about it.
 
I have litterally cleaned and worked with 10's of thousands if not 100's of 1000's multi coated lenses

What is ironical is that (when talking plastics) the Nikon lenses were always the toughest, the most resistant to pretty much everything

take this with a pinch of salt

Surely salt would be bad for the lens :lol:
 
yep, that too

In saying that, the latest range of coatings are so resilient, it would really only be an issue if the salt were cleaned off dry

FWIW, the best lens cleaner I have ever used is: Solution 30

fairy liquid and water is pretty good for a wet clean in the absence of soloution 30. And the best lens cloths are made by pentax

Is this what is meant by "lens breathing"?
I thought it was worse on the 70-200 vr2?

OK, OK, I'm going. . .

Sorry, but microfiber manufacturers are a dime a dozen, and Pentax will be buying theirs from one or more sources with their branding on the packaging.
You want best - use the blue ribbed glass microfibers the cleaning boys and girls do, and car detailers.
Yes their bigger size can be a bit of a concern, but that's more surface area to absorb grease and whatnot.
Those titchy wee things you've linked to - pfft, use once and bin it rather than wash it, esp at £6 a pop.......money for very old rope!
 
I'm amazed. This used to be common knowledge going back years. It's the coating on the lens (all brands not just Nikon) that is susceptible to the acid in breath. Ditto acid on your fingers. You can get away with it occasionally, but if you breath on your lens regularly then it will destroy the coating. Pentax published a picture years ago showing the results of breathing on the lens to clean it.

But...breath is generally alkaline!
