Buying ND filters

I'm wanting to buy an neutral density filter(screw in) and would like to hear which are everyone's preferred brands. Does Hoya make a quality ND? Thanks for your help.

Hoya makes excellent filters. I use their ND 8X filter and it does the job with no color casts introduced.

Hoya also makes less than excellent filters. They have a pretty big range of price....and sometimes with filters you get what you pay for. I'd suggest looking for multi-coated ones to limit potential flare issues or other problems (distortion, non-neutrality, etc.)

I agree entirely with David - you get what you pay for. B&W and Singh Ray also make excellent filters.

Thanks for the help everyone! Much appreciated.

I recently bought a 6-stop B+W, and it's a fine filter, but here's an issue I didn't think of before I bought it. They're dark! :) Sometimes I have to focus first, then put the filter on. If you have the money, it seems like Singh-Ray has the best idea. You can have the filter on, do your focusing, then dial in the amount of ND you want (up to pretty darn dark). Pricey devil, though.

+1 vote to B+W. I use B+W 110 & B+W 106. They are Excellent. If you use quality glasses use quality filters in front of them.
