I knew as soon as I opened the envelope I had bought a quality item. Inside the gorgeous black outer box is a round acrylic container which flips open at the press of a button. The Filter rests on its foam bed. It looks like quality, it feels like quality.Anyone that shoots video using a DSLR knows about camera settings and the limitations this creates in brightly lit environments. This can become a bigger problem if, like me, you like to shoot with the aperture wide open on a fast lens. It was almost impossible to do outside scenes on brighter days. To say I’m very pleased is an understatement.Pros:High quality, no dreaded X or aberrations and it only cost £36. I expected a lens of this quality to cost much much more.Cons:To be honest, there aren’t any. No, I can’t put the lens cap on when the filter is in place, but it’s no big deal to unscrew it and place it back in its case.I am just an amateur film maker so my word counts for nought among photographers. From a film maker’s point of view, however, this is a great bit of kit to have in your bag and for the money, you can’t go wrong.
