Needed a FD filter for a video project.Used this on the Sony 16-35 GM lens, fits perfectly.and super easy to use, just adjust to the shade level you want, then its all ready to go.The quality of the filter is super good!!! especially for this price.I might get couple more in the future for my other lenses as well.

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.

Applied this to my lead lens and its great on those horrible sunny days while your shooting. Haven't experienced any issues, vignetting or darkness unknown. Great product.

Easily the best bang for your buck variable ND filter. Probably the best VND under $100. I like what this filter does to skin tones as well.
