Polaroid Optics 77mm HD Multi Coated Adjustable (ND3, ND6, ND9, ND16, ND32, ND400) ND Filter Neutral Density Filter / gray filter (Camera)
For the price, a perfectly good alternative to the expensive models. Anticipation, I movies with a 550d and a Tokina lens 11_16mm. I could not tell the color cast in the post. Caution should be exercised at the maximum filter setting. Is rotated too
