    Yeah that was interesting. It's about time someone had the motivation to do an in depth technical test of protective filters.

    However, I still won't use them.

    I honestly never understood why some buy really expensive lenses, like $3000 and then put a cheap $5 UV filter on it. I mean come on....

    I think they need to do more testing.

    They do more good than harm. That mid-to-high end filters don't measurably/meaningfully(that's Cicala's key finding) degrade image quality puts to rest the near-urban legend that they're a damaging factor. Can only say they've spared pricey-rare-favorite optics from harm on more than a few occasions. Cicala's especially good at debunking various "flat earth" arguments I see all too often here and elsewhere.

    Why does it bother you? Would you feel better if it were a $50 filter. A protective filter is just a flat piece of optical glass.

    Filters: handy during the springtime when trees drop thousands of minute sap particles into the air: makes for easy,quick cleaning of the lens. Same at the seashore on days when the wind blows a lot of fine,fine salt-air particles onshore...easier to wipe down that flat, exposed filter.

    Mostly, filters are sold as high-profit items for sales associates.
