I bought this thinking it would save me time taking my neutral polariser off one lens and transferring to another. This was a huge mistake. The vari works well but moves too easily making adjustments and keeping the shot settings almost impossible. Autofocus spent ages hunting for the subject and could not lock on, tried manual focus with little improvement but still out of focus pictures. an other wasted purchase IMHO. The none setting on the polariser has a .2 shade to it.

Now I don't have to carry multiple filters thid one does all that I need, just be careful not to go past the minimum and maximum setting and your pics and videos will be amazing.
