Variable ND Filter Quality? Need help to decide.
 
What is the difference between brands, Tiffen and Hoya & ect.?

What do you guys use on your lenses?
I'm using a sigma 18-35 1.8.

I don't use variable NDs generally, as many can create issues (while shooting anamorphic, for example). The best ND filters I've found are from Breakthrough Photography:

As an enthusiast, there are a ton of inexpensive variable ND's out there and I think it is worth buying a cheap one to try out and see if it works for you.

The thing about variable ND's and the cheaper ones, is whether or not there will be a color shift and whether it will show an "X" or uneven filtration at maximum ND. Usually backing off the ND and stopping down the aperture will avoid it.

I assume the pricier ones will address those concerns.

The variable NDs are useful for sure as you would like the aperture to be enough to create a right DOF.

I have used Variable NDs and still use them, on wider lenses like the 12-35 i use a TIFFEN 77mm Variable ND as i found that most of these have a bit of color shift on the outer end near the edges at higher value so using a bigger ND than you need avoids it, i found it very useful when shooting mid day too.

This is a example of what i shot with the ND last year and it was around 11am onwards


its surely useful

Hoya Solas Variable NDX. No colour shift, no polarizing effect and maintains sharpness. It out perform even fixed NDs.
Never thought it is possible a variable ND can overcome these issues. This is the new gold standard for NDs variable or fixed.

I have a Hoya ND fixed filter and I made many tests, then I evaluated the quality of the image with a big monitor. I have to tell Hoya mixes the colors and degrades the definition but it is enough imperceptible. I think it's hard to say that a variable ND filter is better than a fixed one. But if you say so maybe you did the tests too. I wanted buy B&W BW1075251 Neutral density but if you say that Hoya ND variable filter is even better than the fixed one, I will think about it.

Not this one

This is the one

Only just came out a few months ago so not many around and they are not cheap.

Nice!

Great GH5 shirt by the way.
Why doesn't Panasonic send me one? ;)

Solas NDX – The Sharpest – Most Color Consistent – No Compromises

I understand, it is the best ND variable filter. Out of curiosity: do you use ithe variable ND filter with lens hood. Did you buy the filter with the same size of the lens or larger?

Have used a few but the SLR Magic is the best I have seen. No X pattern and is ultra sharp. It has a ring lever and hard stops. Google them.

No lens hood. I use a matte box if needed. I get the largest 82mm and use step up rings.
Solas are generally not available outside USA.

I have the SLR Magic MkII it is as sharp as the Solas but like most variable ND it is vulnerable to polarisation. It allows you to change the angle of polarisation but it is a pain when you shoot in field and does not completely remove it, you just move polarisation from one area to another. It also shift to warm as you dial up the density. It only goes up to 6 stops which is not enough for me. There are times when I need to shoot at ISO 1600 to get an extra stop of highlight on a Blackmagic camera and 6 stops is simply not enough.

Do you mean this one?
https://www.amazon.it/SLR-Magic-Refl...agic+ND+filter

Then .... if I have a Leica 12-60mm lens 62mm, it is better I buy a larger ND variable filter (for the problem of vignetting) or 62mm is better?
I think you don't use lens hood, right?

It is nice to use matte box, but I can't use it. I need a very practical thing when I travel.

You can buy a screw in lens hood that goes on to the front of the filter.
