Cost effective/quick means to the same end
I had researched the qualities and capabilities of an ND filter. What I did not like was that each 'level' of ND effect were a separate lens and to buy a range of them would cost money and add bulk to your camera bag. When I found this variable ND filter, at a reasonable price, I ordered it. I like that, with one lens, I can change the density quickly by a simple rotation of the lens. Where as, if I had a set of ND filters, I would have to guess what effect I wanted, select a lens from the set, screw it on and hopefully not miss my shot. True, for a tripod set up and all the time in the world, you could try different lenses and compose your shot but most of my work is wildlife and at-the-moment shot. A great addition to my camera bag.

Worth the buy
Not very expensive considering what you get out of it and the protection it gives. The quality is good and seems durable...Opens up more options for hard light...

If you rotate your ND filter past the ‘Max’ mark on the filter rim, it can cause an x-pattern, so ensure you’re not over-rotating. Variable ND filters also have limited application with wide angle lenses (they can only be used to about the halfway mark of Min and Max markings because the field of view is so broad). For a wide-angle lens, we suggest using fixed ND filters or ND2-32 or ND8-128. You can also try adjusting your focal length and reducing the density (rotating back towards the ‘Min’ mark) until the colour shift disappears.

by the way, when you use a nd filter , you better not add a lend hood ,the lend hood should move.
