so, I just had a chance to try and use my variable ND filter last night doing long exposures. I got this terrible cross pattern at the higher settings. I just did some research on them, and apparently this is common with variable ND filters? These things are like $150. How can they charge that much if they don't really work at all the settings?
Here's an article I found on a Tiffen ND. I have a Hoya, but they both do the same thing-http://www.ephotozine.com/article/tiffen-variable-nd-filter-review-20475
wow... unbelievable waste of money. I hope I can get a refund.
