ND Grad which type

[gavcam]

Im looking for a ND Grad for landscapes.
Im wondering which way to go Cokin type or circular, Im thinking that the Cokin type would be better as you can slide the filter up & down to suit the shot.

Any opinions & recomendations welcomed.

Using a ND8 (3stop) P121S Cokin, great results

I recently bought the Cokin holder but with Hi-tech filers. Haven't had that much of a chance to use them yet, but no complaints so far.

I've read that Cokin filters have a colour cast, but I haven't used them myself. They are cheaper, though.

I bought mine from http://www.2filter.com and found they have great service over email if you have any questions and fast international shipping; I'd recommend them.

Cheers,

I use Cokin ND filters and i have not noticed any colour cast on them. They are grey, if that's a colour. The Grad ND works well, as you say, by being able to be moved up and down to suit your composition.

The only issue i see with Cokin's is that there is overhang around the end of the lens so a backlit sun reflecting on it will cause flaring on the filter. You may need to consider some way of shading the filter if this happens. A hat works well for me.

Gavin,

I have been thinking exactly the same thing. ND grad filters for landscape work. I have seem the P holders on Ebay http://cgi.ebay.com.au/P-series-holder-58mm-ring-adapter-for-Cokin-filter-NEW_W0QQitemZ150087459263QQihZ005QQcategoryZ43479QQrdZ1QQcmdZViewItem ( Chinese knock-off's ) for about $9.00 + postage. To me that's cheap.

But I haven't seen or done enough research to know:
a) is the P series filter the one to get, what is the difference with the A?
b) how many stops ( eg no#'s ) do you need for most situations?
c) does the one holder work with multiple adapters, eg up to what size lens ( I need 58mm + 62mm currently )?

1. Not positive, but I think P = "Professional" A - "Amateur"
Basically though, the difference is the lens diameter they will adapt to. P Series work on 48-82mm. ASeries work on 36- 62mm. Thus for your lenses either woudl do, but if you think you might get larger lenses in the future, the P Series would be better.

2. I'll leave that for others

3.Cokin use a standard size filter (well two these days - A & P) These sit in a standard holder. All you do is buy an adapter ring for your size lens. You can simply keep an adapter on each lens and slide the holder on the lens as required.. They are bulky though. You may prefer the slimness of specific screw in filters.

I'm using the P121S and P121L, at the moment they are good enough for me - and I'm not so fussy about the colour cast. They are very wonderful to use and I wonder why I did not get them earlier
If I were to upgrade, I'd probably go for the Lee set
