I was given a Cokin graduated ND filter by a guy getting rid of stuff. He said he never used it as he only shot portraits. I was playinh with it the other day and realized that there was a flaw. By flaw I mean as I pass it in front of my eye something makes the view wavy. I have no intention of using the filter and since I did not pay for it I am out nothing but I was wondering if this type of flaw is normal with Cokin filters? I was going to buy a couple of their ND grads but am now hesitant. I cannot afford to buy the lee filters or other high end stuff and figured the Cokins were in my price range.

Resin filters can become distorted if they are exposed to excessive heat. Another issue with Cokin ND grads is that they're a little on the warm side of neutral in general.

If you have the Cokin P filter holder Tiffen makes an ND grad that' fits it and is of much better quality, i.e. it's glass, and, my sample at least, is free of obvious distortions.

The Cokin graduated ND's are fine - I used them for years, before switching to Lee.

Thanks folks.

John, I looked at the tiffen filters and they are out of my price range. Someday, maybe but not with a three yearold and 6 month old and only one income.

Cokin it is. You want to sell me yours, robert? At least I could say they helped someone's fantastic photos

Sure, PM me with your address and I'll send them to you. You can just pay for the shipping. I don't use these filters anymore; perhaps you will get some use out of them.

Robert's experience with Cokin filters is different than mine. All the Cokins I've tried had optical distortions.

You get what you pay for I guess. I couldn't afford the Lee Filters, so I had to make do with the Cokin. I still have Red/Green/Yellow Cokin Filters for B&W work, and they all look pretty clean.
