Decent concept
So here is my take. I'm a little on the fence. First and foremost the good. The good is "I mean what the heck is cooler than a filter that changes density with a switch" omg right. So when it comes to light control ability the options are endless with this filter because it's dark to everything in the middle. super cool right. well the bad. the petty first you can't add or remove your lens hood using it buuuut you don't really need it. I mean it is an ND filter. the bad though. the filter spins freely on the lens once it is tightened. So it makes it very hard to adjust the switch with one hand. I guess that's a matter of what you are shooting. If it's on a tripod no problem but free hand is going to be a bit of a challenge. It fits snug and comes with a nice carrying disk style case. It feels like you are getting a quality filter material wise. It is heavy duty so I would trust my lens to a small fall to it if need be. I think it would be more than awesome for a long exposure I cant wait to try it.

Great quality!
I have been using the 58 mm ND Filter from the same brand and now I purchased the new SIGMA 77mm ND and CPL 2 in one filter. I live in Los Angeles where it’s sunny all year round and this filter is needed and beneficial when filming outside especially when shooting a video.
