Polarizing Filter Recommendation for 45mm lens.

I am looking to get polarizer for my 67 45mm lens. Any recommendations. I am hoping for something in the $50-$60 range and am looking at linear polarizers. Will the work well for the 45mm and Velvia? Has anyone experienced and vignetting caused by polarizers on this lens?

Thanks

I've put a Pentax O2 orange filter on my 45mm all the time with no vignetting. And that filter is pretty thick. I've even stacked it with a thin profile ND filter and still no vignetting. Those thin profile filters cost more for some unknown reason. Must be because it is more useful for stacking on wide angle therefore they have to gouge you more for it.

So don't worry about vignetting and get what fits your price range. 82mm filters do tend to cost more.

Thanks Tuco. I'm hoping that the cheaper ones will work, they go fro $60 to $200 pretty quickly when you start looking at the thin/wide angle ones.

I probably have the thickest polarizer B+W ever made on my 45. It doesn't vignette.

I just had a quick look at a shot of the front of my 45/4. There is a huge expanse of steel separating the glass from the filter ring. I suspect you could come out over half an inch from the filter ring without vignetting.

The Hoya does well in its price range and I use one (a linear) on my 45mm. I don't feel they are as well built as the older Hoyas of 20 years ago. Polarizing with Velvia using the 45 is tricky because the angle of view is so large that differential polarization takes place and can ruin a shot. My suggestion is not to fully polarize the shots with this lens. Also, Velvia can be pretty rich without the polarizer, so use discretion.

I prefer Heliopan and B+W but they are probably out of your price range.

Of course the same applies to any film, not just Velvia. I agree that it is most noticeable with color slides.
The effect is particularly unpleasant in images with large expanses of blue sky, especially when cloudless.
FWIW I have observed this even with less-wide lenses, e.g. 35mm focal length lens on a 35mm camera.

Thanks for the tips desertscape.
I have read about the effects of using polarization with wide angle lenses.
One of the reasons I am trying to keep the cost pretty low is that I don't plan on using it much but would like to have one just in case.
