That's from morons who wipe the lens on their shirt..


On the contrary, it is extremely easy to scratch the front element of
a lens even when using great care. All it takes is one piece of
unseen grit or a tiny quantity of an abrasive substance.

I do a lot of construction progress and publicity photography, and the
opportunities for scratching front elements of lenses are ever
present. Cement dust and sharp sand are both very common on
construction sites, as is residue from abrasive wheels.

Of course, Tony, under such adverse environmental conditions it would be appropriate to protect the front element of your lens. That would be an exception, not the rule. You have been posting as though using a filter for lens protection should be the rule. I would definitely disagree with that.


I try to avoid cleaning my filters on site unless absolutely
necessary, knowing that any rubbing action is likely to abrade the
filter coating. And it does; this is evidenced by the scratches on my
filters.

Given that the coating on some of my filters is identical to that used
on lens elements, it is easy to see how lenses get damaged through
careful cleaning in a dirty environment, let alone careless cleaning.

You can continue to disbelieve this if you wish, Stacey. The
condition of your lenses is not my problem.

But others with a more open mind may wish to take note.
