Nuetral Density filters OEC vs. Hoya?

[colormesilly]

I was thinking of getting a neutral density filter, or two, but was wondering if there's a quality issue when compared with OEC to Hoya brand. I would be using it for mostly landscapes.
Any help is appreciated.

There is differences in the quality of filters from one mfg. to another.
I use Shing-Ray GND filters and pd about $100 each. They are rectangular and fit into a Cokin "P" holder which screws onto the front of the lens with an adapter ring (you need a ring for each filter thread size of your lenses, they are cheap) You can get an ND filter that screws onto the lens BUT if go with a GND filter you should avoid the screw on type. They put your transition line across the middle of the filter and you cannot adjust it. With the rectangular filters, you have the flexibility to adjust it up or down and at angles, seldom,if ever, you would want it in the middle of the shot. You can also stack the filters very easily.
Good brands of rectangular filters are, Shing-Ray, Hi Tech and Lee
