The common advice is to put a UV filter (or other "clear" filter) on each and every lens you own to add a physical layer of protection over the front glass. Is this really a good idea? What do you do?

I had a photography instructor that joked that you should only put a UV filter on your lens if you're afraid of your camera getting skin cancer.

I personally don't use UV filters. I use a lens hood to help protect the front element (both from flare and physical contact) instead. Mostly I don't use them because the image quality tends to be worse with a UV filter. I paid a lot for nice lenses, I don't want to degrade them by throwing more glass in front of them.

It also bugs me how eager camera sales people are to sell me a UV filter. Feels too much like an "extended warranty".

I don't use them. If you take good care of your equipment, it isn't needed.

I use them, especially if I am out hiking. Murphy's Law states that if I don't, something WILL definitely end up scratching my pricey lens. It depends on how prone to "mishaps" you tend to be.

I prefer lens hoods. They've saved my lens more than once when bumping into things and people!

I use them on lenses which I don't currently own a lens hood for. Even then I only put one on when in hostile environments (visits to young niece/nephew who like to poke the camera is a key one).
