Daaaaaannng. K Wave is the one I had success with. And With Us store on the filters.
And I 100% disagree with the statement about "just buy one from Adorama". Why exactly? Just so I can get a warranty? How about I just buy the State Farm personal articles policy for 80 bucks a year that also covers me against theft...and I'll pay for it with the $1300 dollars that I saved by buying from S. Korea. And hell, I could even buy an
Avata 2 with what I've got left. Also, Adorama is milking this for all it's worth, check the price of their ND filters...lol. So I guess if you don't like saving money and getting screwed and HAVE to get your 1 year warranty, then I guess Adorama is the one for you.
