Thank you for the test shots Paul. They clearly show that there is a color shift, but I guess there is some in all filters and it looks like it can be corrected several ways to achieve the (mostly) simmilar result.

Thanks

I use LEE filters 100x150mm (4"x6") with the Cokin Z-Pro holder and the combo works just fine. The Big Stopper does add a blueish cast to the images but that is easily circumvented with either Custom WB or post-processing.

This shot had a 4-stop Hoya 77mm screw-in ND filter, then the cokin holder with the Lee Big Stopper and a Lee 3-stop soft grad ND filter for the sky, all stacked for a nice 17-stop filtration. Gave me an effective f-stop of f/3983.

I much prefer the Singh Rey 10 Stop Vari Filter. Gives you a full range from 1 to 10 stops. The nice thing is you can focus and compose at 1 stop and then rotate the filter to the level of stops you want and then take your picture.

Whatever you get, variable stop filters are the way to go as your camera cant AF with a 10 stop filter on the front, and you can't see anything through the view finder. I also rarely use all 10 stops. More often I want to be at 4-5 stops. The only downside is it will cause vignetting on UWA and sometimes can add a color cast on wider then 20mm.
