I made a visit to my local camera store in LA trying to buy a "protective" lens for my new digital camera. The salesman advised to buy "UV" over "Skylight" for digital cameras because they had some kind of advantage, although he couldn't remember exactly why. If you were in the market for a new filter for "primarily protection purposes" for a lens on a digital camera, what is the prevailing opinion on which to buy? And I assume you want to buy the best piece of glass you can get (something in the $50-$70 price range vs. $30) if you'll be leaving it on the camera all the time...any thoughts? John
