Lens Cleaning?

Hi all,

Today I used the bottom of my T-shirt to gently wipe some stubborn dust of the front element of my lens (i.e. I took the filter off and cleaned the lens itself). Quite by chance I've stumbled upon a post on a web page this evening saying that you should never use anything but an approved lens cloth to clean the front element as alternatives can erode the coating (???). This appears to be a post from a non-pro and I'm suspicious about the reliability of such info; but another part of me is suddenly worried as, although I don't make a habit of it, I have done this before.

Is it nonsense do you think? I would be inclined to say yes but I'm really not sure. My lens is the Canon EF70-200 F4 L by the way.

Cheers,

Karl

Better safe than sorry with a nice lens like that. In my camera bag I always always have a lens cloth and lens safe cleaning solution that comes in a spritz bottle.

Thats what I've been thinking too. It doesn't hurt to try it when really needed, but its best not to become dependent on it.

OK, thanks a lot guys. Just thinking though, can a 100% cotton T-shirt really do a lens damage? I was very careful.

Definitely in future I'll carry my lens-cloth around!

Have you tried Carl Zeiss pre-moistened wipes? I use them regularly, and they're excellent! Usually easily available at any department store.

I really doubt that a T-Shirt (as long as it is clean and the cloth is soft) can do any damage to the coating of a lens. As far as I know the coat is sprayed on the lens and burned in so that you can't really damage the coating itself without scratching the whole glass.

Thanks Stefan, I can breathe a little easier now!

The T-shirt was clean and is 100% cotton - I really can't see see this damaging a lens if done frequently, let alone just once!

As a precaution though, that lens cloth is staying in my case, LOL!!!

Jeff said it well. Don't make a habit of it. It will scratch your lens in the end, if you continue to do it. I use Kodak lens cleaning tissues. Think thin tissue paper and you're not even close! This paper is so fine and soft it's unreal. Take a couple of those babies and fold them over, mist the lens up with yor breath a little and wipe. Smeer free and perfect results every time. I strongly recommend them.
