Fit's and functions properly. However if you really make it dark it does cause a purple color shift. This is not an uncommon problem in all but the over $100 filters. Still a very good item.

I got this to put on a lens baby and use for IR photography. It takes beautiful pictures!

I love these filters, but I really wish you could put your lens cap on them. There is no loss of sharpness like other cheap variable NDs have. Love it. Would certainly reccomend to another cinematographer. I use them for getting the correct shutter speed with my cinematography.

I have multiple expensive FADER 2 Variable ND's and this cheap manufacturer works great, use it for jobs. But it is not as sharp as the Fader Nd's. But the fader ND's are $250-300 each. so this is a good comprise.

Did not come with cleaning cloth as advertised. Also could be cleaner on arrival. In addition the thread size is not the same, so while I can stack I would need a totally new caps/filters.
