Are these Lee filters or are they a different brand and suppose to be "like" Lee filters? I'm getting ready to buy a couple more graduated ND filters and was just curious because these seem much cheaper than what B&H or Adorama are selling the 4x6 Lee filters for.
Here's the link http://www.calumetphoto.com/item/LE51395/![]()
I didn't know if there was a difference since it says "Calumet/ Lee". Just wondering if anyone knew, Thanks
