I'm on a tight budget for an ND filter. I'm often taking pictures at the beach and it's awfully bright. I also want to do some time lapse footage in day light with motion blur, therefore I need at least X8 (I hope that's enough...). If someone has experience with Hoya filter let me know if they're any good. I wish I could spend $150 on a single filter but that's out of the question. Is this any good: [ame="http://www.amazon.com/Hoya-72mm-Neutral-Density-Filter/dp/B0000AIS27/ref=sr_1_1?ie=UTF8&s=electronics&qid=1265561022&sr=8-1"]Amazon.com: Hoya 72mm NDX8 HMC Neutral Density Filter: Electronics[/ame] or multi coated: A72ND8XGB Hoya 72mm 8X (0.9) Neutral Density Multicoated Glass Filter Any info is appreciated. Thanks.
