I want a variable ND as it is more convenient than carrying a set of ND filters.

Looking at this variable ND (x3-400) from Hoya.

https://www.ebay.co.uk/itm/Hoya-77mm-77-mm-Variable-Density-NDx3-400-ND3-ND400-Neutral-Camera-Lens-Filter/252087175121?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649



Does anyone have experience of variable ND filters?  
My previous experience is that they cause colour casts but there are a number of different makes now.
Any suggested makes?

Not answering your question but I believe they are a pair of Polarising filters in variable opposition, that might explain the colour variation?

Yes I have an older variable ND but it is in Spain but also causes colour casts which are very difficult to remove.
I am hoping these new Hoya ND filters may be different but I dont want to blow £100+ on a filter that makes colour casts.  I can buy a set of Lee 150x170 filters which cost £250 but they come as a set 0.3, 0.6, 0.9 (1,2,3 stops).

The x3-400 effectively gives me variable 1 to 6 stops.

Simples, take a leaf out of Eric's book and buy it from somewhere like Wex, on-line, if it fails to make you smile then send it back.

I find that process works well if you live close to the store and can take it back but it irks me to have to post it back.  Not entirely logical I concede but.....

But the point is the distance selling rules mean you have a right to send it back, without stating a reason.  If you go to the shop to buy it, it's up to their goodwill if they are prepared to have an even slightly used item back in stock.

Decided that the Nikon 14-24 f2.8 needs the flat ND so that is the way to go as I have the filter holder for it.


However the Nikon 14-30 f4 Z series lens will take 82mm screw in filters but I dont have that!  So decision made.   I will continue with my 14-24 f2.8 on my Z7 using the FTZ adapter and on my D850.  Seems so much easier and lesser cost!

I Fail to Understand why the use of ND filters,..here in Europe light level is rather low, f.ex. , in summer ,100 iso at 100sec. between 2 - 4 midday usually requires f11...equally ,6400 iso at f1.4 , a difference of six f stops could be used ,which is easily overcome by today´s camera`s..and anything in between, enabling the photog to play with DOF,..and as mentioned , they`re supposedly polarizers, so why then not resorting to those, since you seem to have them already anyway..?..

Waterfalls etc. is the only reason I can think of.

I was dismayed when I discovered my D1 minimum ISO was 200, I had travelled some distance to make my first digital photographs of some brightly lit waterfalls in Yorkshire, but faced over exposure or frozen water droplets.

What about just mounting 2 polarizing filters?
