This picture proves nothing. You should have shown a shot of the lens front element AFTER the picture was taken. Why didn't you?
From the Author: "Some of you are cringing and expecting that I toasted my expensive lens. No such thing. After a bit of immediate field cleaning, the front element of my 14-24mm looks like new."

You are telling these people in effect that the front element on a camera lens will never sustain damage and/or that if it did sustain damage, ii would have no effect on image quality.
No. I'm not saying that,
you are saying it , what I'm stating is that filters offer no protection.
If you are truly afraid of flying objects, appearing out of nowhere when you're taking a photo inside a museum, at a dinner party, at a studio shoot, or 99% of most
normal shooting conditions, then you should wear safety goggles 24/7, because anything that can fly and break a lens, has, twice the probability of striking your eyes, and sending you to a hospital. And I'm willing to bet my bottom dollar that you don't walk around 24/7 with safety goggles.
So in real life under 99% of most shooting conditions the probabilities that something will damage your lens are microscopic, but fear mongers hang on to that microscopic fear and magnify it in order to make you buy something you don't need.
That's correct to a certain degree. As long as you keep your light source behind you, a surprising large amount of damage will not show up. However, the dirty little secret the anti-filter crowd won't tell you is that situation can change dramatically when the light is coming from the side or the front.
There's no secret, if you have a large gash in your front element and shoot directly into light you'll get tons of flare. How likely is it to get a large gash in your front lens element under normal shooting conditions? Less than 1%, how likely that a "protective filter" will prevent it = 0%
The bottom line is, when it comes to filters there's no right or wrong decision.
Hello, if filters were free, your statement above may hold water, but when you're parting with $50, $70 or $100 for something that does nothing, you betcha there is a right and a wrong decision.
However, if you decide to use it and find it's degrading the quality of your image, you can always remove it.
Well that's foolish, because you can only tell once you get home and view them in your screen, at which point you can't jump in time machine and go back to your kid's birthday celebration to retake the photos.
Bottom line, show me some data, some science, in stead of your boogeyman marketing. What is the PSI Impact resistance of a 77mm B+W filter? How about the Abrassion Tolerance? what is the maximum weight lens it's designed to fit?
Go find some independent measurable protective data and then we'll tack, until then, see you October 31st, I'll be giving out M&M's and hoya filters.
