    I used too, until I saw pictures of comparisons with and without. Even with cheaper lenses (assuming lower quality). A direct hit to the main lens caused very little marks on the glass (using slide hammer, I think 3# slide). But a lens with a cheap filter on the front. Would get several marks (from the broken glass of the protector hitting and marking the good lens glass). The test lenses were all MF lenses from different brands. Would have several of each one (same exact lens). One would get the filter, and other would have nothing. Believe it or not, the lens barrel / actual lens piece mount would break more often than the glass (again the cheaper lenses). So, for the most part just chips in the glass were the worst, until they used more force than just letting the slide fall on the slide hammer.

    After I saw that article. I thought to myself. How thick is that filter. They are all pretty thin actually. They actually take less abuse than the lens itself. And when they break, cause more damage than if it had not been there in terms of marks on the lens.

    I use UV filters all the time and I think they work great.

    The 72mm, while more expensive, has the necessary room to keep the condensation off your desk all day.

    I have never used a filter on my lenses.

    Until you do side by side comparisons you have no idea that it saved anything.

    I remember a similar article and it made perfect sense to me not to have an additional thing that could shatter into my expensive glass.

    Filters have saved front elements and/or lens-side filter rings on at least a half dozen of my lenses. And no, they didn't shatter. Try acquainting yourself with evidence-based discussion sometime. Cicala is pretty good at it. You're plainly not.

    For me, it was never about protecting the front element. I find the lens hood to do a good job of that. And the front element is pretty tough.

    I just found the idea of a UV filter odd on a digital camera that doesn't need one like film cameras did. People make such a fuss over "good glass", pixel peeping and comparing mtf scores... looking for the sharpest lens. then put an unnecessary piece of glass in front of it.
    Even of its an expensive filter...it just seems weird. In 25 years of shooting film and digital I've never wrecked a lens.
    Maybe I'm just lucky.

    An evidence based discussion is what was lacking in your post. I was just pointing out that if you don't do comparisons with and without a filter it is merely speculation that the filter protected anything.

    The only time I use a filter is if I am going into conditions like blowing sand or some type of condition where the lens will could easily get dirty, splashed or grit. Otherwise the lens hood does a better job of protection. If you drop or bang the lens a filter is not going to help. If something smashes the lens, the filter which is a lot thinner and less durable, has a higher possibility of cracking and scratching the lens glass. At least that is my opinion.

    I always use B+W 007's or Fuji (not tested in that article). Its purely for protection only. I have sold the odd lens and have found that advertising that a protective filter has been on the lens since purchase always gets a quick sale at a good price. I might sell them without the lens as quick but consumers always like the fact that the glass is protected, as I would do as well. I don't like hoya, and that was confirmed (to me ) in that article. I used to get B+W 010's but read an article that there is a small amount of distortion with them, whereas the 007 has none, which is fine by me.

    Er, that's why I use them, Chief. No confusion about causation when it comes to damaged-vs-undamaged front elements and absence/presence of a filter. But then this really wasn't the point of Cicala's article.
