I was looking for ND1000 for fairly long poses. I chose this one and I'm very happy. It does its job and does it well. Tip: do NOT buy variable filter (or so set it on price) as they are often of poor quality, you will have marks on your shots. Buy more a ND400 or ND1000 like this. 67mm is the size of my biggest goal. I bought a set of adapters, so I use it all :)
