Quality not compromised.

Questo è il terzo ND variabile che compro, gli altri erano filtri economici come il Fotga (che costa pochissimo). Ovviamente c'è una bella differenza: i due filtri montati sulla stessa lente (Zeiss Planar 50mm) e registrando un video a 4K sulla GH4 danno delle immagini profondamente diverse. Il Fotga fa abbassare tantissimo la nitidezza anche tutto aperto e la croce nera si forma molto prima della fine della regolazione rendendo inutile di fatto usare buone lenti, c'è da dire però che registrando video in full HD con la mia vecchia Canon 60d questa differenza sulla nitidezza non si notava così tanto. Il Tiffen invece mi sembra un ottimo compromesso: la vignettatura non mi sembra eccessiva anche su grandangolari e la nitidezza sembra non risentirne particolarmente: con il filtro al minimo sullo schermo di un Mac retina quasi non si percepisce la differenza tra avere il filtro montato e non averlo. Inoltre è possibile spingersi in avanti di diversi stop prima che la vignettatura arrivi a valori inaccettabili e questo permette di girare praticamente sempre ad 1/50 con aperture ridotte per avere meno PDC. Per adesso non ho usato tantissimo il filtro ma dai test che ho fatto mi sento di consigliarlo.

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.

great filter i live it
