' /> Tip: put your camera on a tripod so not to change position. then take the same photo with and without a good multicoated filter. Report back if you see differences. (In strong contra light you may be able to see one ADDITIONAL flare mark, caused by the filter on top of the marks produced by your lens. You will then notice that it doesnt make a differnce whether there are six or seven flare marks in your photo. When your lens doenst flare, the filter wont flare, too, because it is coated as good as your lens.)
And please stop fooling people like vieux loup, who try to learn. Only talk about what you have tried and what you know, skip the myth you read or heard from some unvarified source .

I actually give some (from a lot of) examples of problems UV filters can give with LIGHT.
If you want to go and call the serious photographer who blogged about what he encountered a liar, go ahead, I posted the link to his personal site.
If you want to call the article on luminous landscape fabricated, go ahead and tell them that.
If you want to call all the ghost lights caused by cheap and expensive UV filters a hoax, fine. Just do a google search for fun.
If you want to not believe everyone who had a broken UV filter scratch the front element, if you want to believe front elements actually break easily, fine.
And if you want to believe that everyone who experiences AF problems with certain lenses in certain light conditions, only when they had an UV filter mounted are all making things up... fine.
But stop writing as if I am spreading myths, I am not. And UV filter ghost lights are NOT flares, they are a mirrored-through-the-optical-axis reflected image, and happen with expensive multi coated filters too.
Myths are that thin slabs of glass have magical impact absorption powers, and that they will not have an impact on IQ.
I do not have to make a photo with and without multicoated filter in problem situations: They have been done many times, and can easily be found on internet. I linked to some only this week, and even today. I even linked to a funny youtube video which demonstrates just how difficult it is to actually damage a front element (when you do not have any swans picking into your lens).
But just for you, another link. Because you must be joking if you think I will actually go spend money on an expensive UV filter just to show you what others show already.

You are free to put UV filters on lenses, whenever you want.
