The idea of paying extra money for an "L" lens and then slapping a piece of plastic on the end seems paradoxical. On the other hand, paying an extra $200 for that same piece of plasic seems like a bad idea as well.

Does anybody have experience with polarizing filters for 77mm lenses (i.e. 17-40L) and whether there is a big degradation in picture sharpness with cheaper filters? I'd like one in the $50 range if possible, but don't want to spend too little for a filter that will ultimately fight against me.

I have the low profile Hoyas and a generic brand from B&H. No difference at all. It's how you use it :)

Popular PHotography reports no difference between cheap and expensive filters on images. I have cheap Hoya and a S&W CPL's. No expensive ones to compare it to.

I've been wanting to get one for awhile... Leica makes one but it's on the steep end of the spectrum. I've heard that there is a difference in quality, but I'm not sure how much, or if it really matters. I kinda wanted it for tomorrow, but it's a little late :-/

I'm not sure about this but from what I heard you loose 2 stops with cheap polorizer. If you get Nikon you loose 1 and 1/3 stops. So it is how much light they transmit that counts.

I expect canon is the same way.
