Filtro ND2-ND400 Variável (1 a 8 2⁄3 stops), diâmetro 67mm

Well, didn't expect it to work but yea, this nd filter works with a 67mm from the Sirui Anamophic 50mm lens. and it helps a lot when outdoor. I didn't see some color shift or vineating but that's from first initial test, will be trying it more tomorrow and will update this.Update, love it so much I ordered another one :)

This thing is a must have for anyone shooting in bright light.

This immediately became a necessity for outdoor shots. One thing I have found though is that if you accidentally twist it past "MAX" when trying to set the filter density, you may wind up having the filter run a black shadow through the centre of your image. Just steer clear of "max" and you'll get great outdoor shots.

Works as expected, a much more affordable option in the market.I have not tried the darker ends of the ND spectrum (which I would also advise against regardless) to see if it causes any image degradation.It has worked well so far.
