Absolutely for a polarizer. But as dryfly said I don't use it in low light either. I can't remember exactly but I believe it takes 2 f-stops of light down (??), which is a bit much sometimes. Great for glare, and skies especially (As dryfly's amazing skies show..) Definitely get one, or a filter of some sort as its alot cheaper to replace a broken polarizer than a broken lens if you drop, stumble with, or fall in the river with your gear as much as I do...like the village drunkard in some early Irish novel.. I am almost embarassed to post pics now but for examples why not..
