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.
Really good for the price
Better than expected
Important
This is a wonderful piece of kit. I have never really played ND to much. but the CPL is freaking NIIIoCE.However this is the important part and it should be covered. The ND handles stick out LIKE A LOT. so much so that the hood no longer fits on my 24-105mm so kinda annoying. Either CPL/ND or Hood but not both at the same time
Used sold as new
I received a used non working filter! The box was already torn open and the plastic seal was cut on the sides. I’m truly disappointed in this and how the company could let this happen.

Just at the end
A
yes, , the filter could do that
A
No. It is two cross polarized filters. When they are aligned, it functions as a simple polarizing filter and has a 1 to 1.5 stop light loss. Moved out of alignment it produces up to a 5 stop reduction of light.

This one is high quality materials, and contains both a variable ND filter + a polarizing filter. Also - most variable Nd filters show and “x” pattern when they’re turned to the max, essentially making them useless at full power. This one shows no “x” pattern. I’m happy I bought it! Very high quality and sturdy.
