Superb quality filter
on 19 January 2012
I've recently got into DSLR Videography and I've been wanting a way to get low depth of field shots in bright light. This is where ND filters come in. I read a ton of different reviews and articles and decided that I wanted a variable ND filter as I didn't want the hassle of changing various graded filters whilst I was out shooting video. I'd read that some cheaper filters could have a color cast so I decided to pay that little extra and get the Tiffen. This filter is a superb quality. The build quality is perfect. It turns very smoothly and is nice and solid. It is advertised as having 2-8 stops and although I've read reviews saying that anything above 6 stops will produce a color shift (basically a dark 'X' on the picture) I have been able to shoot with 7 stops without a color shift. The 8th stop does seem to be a bit too close to maximum so I'd personally not go that far. But 7 stops is still a lot of light reducing power and I have been able to shoot in midday sunlight at F.4 with a nice low shutter speed without having to over expose the image. Also, since it has a low profile I'm getting no vignetting at all. I'm shooting with a 17-40mm Canon lens and even at 17mm there is no vignetting. I am shooting on a crop sensor camera though (500D) so I can't comment on the performance on a full frame camera. And the best part is that there is no noticeable color cast that I can see at all. I've very critically examined several different bits off footage I shot using this at various stops in various light and the colors all appear natural. I can't reccomend this highly enough if you need a variable ND filter.
