""Do you use a "protective filter" on your lens? I encourage you to take that filter off your lens and leave it off. This is, of course, one of those perpetual nit-picky arguments photographers indulge in. You know, like whether Nikon or Canon is better, whether Leica lenses are worth it, whether you should use a tripod with 35mm, and so forth. This is just my answer for it, and may not be yours. But I'll make my case. In the old days, often the objectives (front elements) of lenses were made out of glass so soft that merely by cleaning it overenthusiastically you could make tiny scratches on it. Also in past times, lenses passed UV light, which could throw off TTL (through-the-lens) light meters and/or cause film to respond in weird ways."
A nice article explaining flares from bright lights and how you can try and reduce them using filters.
Well, actually it does depend on the situation. I'm sure the top end filters from the respective companies' aren't so bad. However the flare thing does happen, so take note if you're shooting a bright object or light source.
