How much Neutral Density with a polarizer?

[Coppatop85]

Hello! I am looking to get a ND filter in order to get some cool effects while shooting ocean scenes, moving water, clouds (etc), but I plan to shoot with a circular polarizer which to my knowledge, reduces the light by 2.5 stops. I was thinking of getting a ND 10 filter after seeing some of the pictures taken with them, but if I use that WITH a CPL, do you think that will be too much? Should I get maybe a 6 stop instead? Does anyone here have any pictures taken with a CPL + ND filters? Thanks.

A polarizer will vary depending, not on the orientation, but on the make and variety. My B+Ws are around 1.5-2 stops. But the filter factors are cumulative. Bear in mind that if you want the ND effect on the photo and the polarizer's darkening of the sky relative to the clouds you're almost certain to see blurring of the clouds due to wind.

My tiffen CPL is from 3/4 to a little over 1 stop .
My Hoya CPL [ I don't like it - to hard to turn and clean ] is a little under to a little over 2 stops .
My B+W's are real close to 2 stops to a little over 2 stops . They are KSM's and I like them the best .
How many stops doesn't really change , but the a little under to a little over does change with the time of day and type of weather .
I have CPL filters on my 10-22 and 28 that only come off for cleaning and are replaced with spares . No UV filters because of vinagrating [ dark areas at the edge of shots ]
My other lenses have UV filters and add CPL's to either hi-light sky or trees [ make bluer or greener and cuts down on glare off water , leaves . reflections ]
You will see the least stops on the 50 and probably really close to 2 1/2 stops on your other lenses .
I would put a protection [ cheaper ] or a UV filter on each lenses that you take to beach or other moving water . They are a lot easier to clean than a lens and a lot easier / faster than to change than clean a lens .
You can find sets of filters on EBAY with a CPL , UV , FD fairly cheap - by that I mean sometimes the S/H is more than what you are buying .
Watch here and check out KEH - they sell used filters .

I am looking forward to getting an answer to this question too. I am currently in the hunt for ND filters too, and i already own a Hoya Pro1 CPL.

So i am wondering if i should get one B+W 1000x and use it alone, or B+W 64x and B+W 8x. Also i am wondering what happens if i stack the 64x, 8x and the CPL all together :)

Anyone?

There is also the option of the Singh-Ray Vari-ND. It is adjustable from 2-8 stops.

I have one and use it in tandem with a Hoya Pro1 CPL...I just got a month or so ago, so I am still getting used to it...but it works well.

Wow, that's amazing, and expensive... and they don't make the size I need (67mm)

I have 2 77mm lenses, but I also have 2 67mm...I just purchased a step up ring and all is well. Not sure I would recommend the standard Vari-ND, CPL and a step up ring on a ultra-wide lens...it will vignette pretty bad...:D

:confused: Vinagrating is not in the English dictionary. Vignetting is, and vignetting means illumination fallof at the peripheral areas of an image.
