Thanks Jake - I've got it - you guys with proper video cameras have up to 6 stops and high base ISO.
You've got it made!
I'm waiting for the GH5 with built-in NDs ;-))))
With this starting point of 800 I presume you don't buy lights just candles?

I have one of those vari-ND filters I use on my DSLR's
That works great to just dial in the exact amount of reduction I need. I've shot at F1.4 outside in the blazing sun. Pretty cool.
The C300 will go to 20,000 ISO
For really low light I usually go about 11,000 without much noise. Over that it needs noise reduction.

Good suggestion, I've always steered clear of those but maybe I'll have a rethink.
There are quite a few of wildly varying prices. Can I ask which you use?

I bought some of these in different sizes to accommodate my lens.

The first I bought as a test but I don't see where it degrades the quality so I bought the other sizes.
There are more expensive one's but for 1080 these seem to do the trick.
But I guess the best test will be with the GH4 or other 4K camera. So whatever camera I end up with I'll see if these will work.

Thanks for that - very encouraging that it does OK in real world shooting and the price is right.
I remember Phillip Bloom testing out the Heliopan
http://www.amazon.co.uk/Heliopan-Variable-ND-Filter-77mm/dp/B004SSDE30
but at that price can't make any mistakes.

Yeah that price is steep. And actually who is to say the glass quality of that one is any better than the cheaper ones.
Just because it's double the price doesn't make it better.

I agree, we're after the cheapest one that does the job - not the most expensive.

I have the cheaper EBay Vari ND and it does great, the largest filter I needed was 77mm and then I bought step rings for all my lenses, so I can use it on my smallest filter thread of 46mm. They do work great and I have shot at f1.7 while using 800 ISO in bright sun. I recently bought a new lens with 82mm thread and bought the Tiffen Vari ND and can recommend it.

Thanks guys for your comments on those Vari NDs. I must say I had stayed clear because of the inherent problems of two polarizers being rotated - but if you guys are getting the results you need - plus as the GH4 is base 800iso, then I'd better reconsider.
It seems one can't go to the limits with these variND - so in reality how many stops do you reckon you can get with the Tiffen?
<<<<<The C300 will go to 20,000 ISO For really low light I usually go about 11,000 without much noise. Over that it needs noise reduction.>>>>>
That's impressive.
Suppose the next question is how high the GH4 can be pushed.

For stock shooting I wouldn't go over 1600 iso on my 5D2 and if the GH4 does the same I'll be happy. I don't use noise reduction software but it's not just iso sensitivity in lowlight it's fast lenses f1.4 on my Canon, I have f1.7 on Lumix M4/3, shooting at blue hour for night scenes, possibly dropping shutter speed depending on the subject matter and high iso.
I think 8 stops is pretty fair on the Tiffen, 2 to 8 stops, if you have a bright blue sky dominant in the shot them maybe 7 stops as you can get an uneven polarizing effect, no sky your good to 8 stops without colour shift. Got mine at B&H for a good price in comparison to Canada where availability was not good.
