ND filter with Nikon D90 - Cokin or others?

[pburness]

Hi,
Although this isn't a direct Nikon question, I am using a D90 so feel fairly justified asking it here.

My question is what is the best high density (8 - 10 stops) ND for use with my D90?
I've heard that when using the Cokin, it suffers from reflections due to light entering the space between the filter and holder. Has anybody else suffered from this?

That could be the cause of it, but it's generally reckoned that Cokin filters have a slight colour cast - (different filters, different shades). Easily fixed if shooting Raw but could be a nuisance. Lee Filters (similar kind of kit) have a good reputation but a considerably higher price.... you pays yer money, etc.

hi as for the density it depends on how what you trying to do
trying to get a misty water effect or trying to balance the bright sky to the ground
i would suggest getting a few if the pennys allow it cokin do a grad set that can usally be found between £45 and £60 i belive theres 4 filters in this set or buy them seprately about £15 each i have a 4 6 and 8 and some times use 2 together depending what im photographing and trying to get
I belive what i wrote is right im sure if not some one will put it striaght i hope this helps

I don't think "Grad ND" was mentioned.... it was the 'Big Stopper' - one dark filter.

Correct, It was a big stopper style, but importantly, I had heard that there are issues with using the Cokin style due to reflections and light speckles. So I was trying to determine if anybody on this list was using the Cokin filters and if they are experiencing similar problems.

Well there's no doubt that screw-in filters would mean reflections and light speckles wouldn't happen, but with the square filter systems (any brand) there is always the risk of light leaks behind the filter. I've never noticed these problems with my Cokin setup - but then I've never noticed these 'colour cast' problems that I keep reading about.

Why not get an ND Fader? Screws in and gives you ND4 to ND400 in one filter. Or make a cheap one by opposing to circular polarisers?
