I cannot say enough great things about Hoya® Filters, both the company and products. You definitely need to check out the Solas Infrared ND Filters I talk about in this video.

Whether you are doing film work with a slow shutter speed or time lapse in broad daylight these are great. If you just want to slow down the wave action and get a misty mysterious look in your long exposures, again use these.
These filters have a really neutral color balance and also include an infrared filter. Modern sensors are so good that when we do really long exposures our sensors are starting to pick up infrared light and noise.  You’ll start seeing it in the purple and pink fringing in the shadows. This will induce headaches when trying to correct this in post-production. These filters will eliminate those headaches. Use them, you will love them.
