I was wondering how many of you use it and how often?
I know how it works but does it make that much of a difference?
Which ones are the better ones of the bunch?

I keep mine on all my lenses all of the time for one reason... protection. The best are B&W due to their brass ring. Hoya are fine though. Polarisers screw onto the UV just fine. They do a great job of cutting glare.

I use quantary uv filters on both of my lenses and keep them one at all times. I figure it's better to scratch a $10 filter instead of $200+ lens.

would leaving them on all the time affect the picture somehow?

I don't think the UV filter affects the photo, but I guess that the polarized filter would have the same effect that polarized sunglasses would have. All I know is that I have a red tint filter which makes all my photos red, supposed to be used for black and white photography.

I don't find that it has a negative affect. At least not as much as a scratched lens. They are designed to cut glare not tint the image.

I use high-quality UV filters on all my lenses, all the time. (See this thread for a link that shows the difference between a low-cost non-coated UV filter and a high-quality coated filter.)

Always, unless I´m using ND og pol. Mostly just to protect the lens glass.
