more light stop blocks from the nisi 82mm one, but of great build quality. a bit heavier. good glass on this one, works greatly.

I debated for a while before I finally purchased this Variable ND filter. I knew it was important, but was always able to get by without using one for the most part unless I was shooting in broad daylight with no cloud coverage. After making this purchase, I don't know how I've gone so long without this.There are a few things to know when purchasing an ND filter. First, you want the Tiffen Variable ND. There are a few cheaper (as in $15ish), but they are extremely poorly made and will give a dark purple cast over the footage when the ND is turned up. Also, cheaper Variable ND's do not like zoom lenses, so prepare for nasty colors when zooming in. I have experienced none of those issues with the Tiffen.There's another, much more expensive Variable ND by Hoya, which in my opinion is not worth the money at all. Dave Dougdale did a very comprehensive review you should definitely check out comparing multiple ND's, and he preferred the look of the Tiffen over the Hoya which is twice as expensive.This is just personal preference, but when buying and ND, or any filter for that matter, buy the 82mm thread unless you absolutely don't want to for some odd reason. The reason for this is that they have multiple step down rigs that will allow you to change the filter thread. For example, I purchased the 82mm thread, and purchased a 82-77mm Step Down, 82-67mm Step Down, and 82-58mm Step Down ring. Now, instead of buying a new ND filter for all of my lenses and spending hundreds of extra dollars, I can buy a three dollar adapter. Yes, you'll have a much bigger filter on the end of your camera and it will look awkward, but you'll also have hundreds more in your pocket so it's all good.On a more technical term, I was able to keep 1/50 shutter at 24fps and f/4.0 with my A7s on a remotely sunny day with the ND set pretty high. I had to go up to a f/6.3 once, but without the NDI had to shoot at an f/22 and I was still +2 stops over exposed, so that just goes to show you how much range this ND gives you.If you ever plan on shooting out doors and keeping your shutter angle at 180 degrees without setting you aperture absurdly high, you need this. There's no other way to put it.

プロが使うのにとても良い商品です。モワレもなく快適に使用できます。

Reçu en temps et en heure, le Tiffen est le meilleur filtre ND variable niveau rapport qualité prix et durée de vie il n’altère pas la qualité des images

I was doubting about the quality of this but it didnt dissapointed me... in fact I am very happy with this filter... I shoot a music video this past week in the middle of the day bright and sunny and I put this in front of my lens and I was able to open wide the lens and got a nice blur barckground thanks that the filter allowed me to go wide open... previously I shoot another video and I couldnt do it wide open and get blur background cause wide open the video is super overexposed... all I could see was white in the screen so i had to shoot at close aperture which doesnt give the bokeh. Thanks!!
